Thinking about a 2–3.5″ lift on your American pickup – RAM 1500/2500, Chevrolet Silverado 1500/2500 HD, GMC Sierra 1500/2500 HD, Ford F-150, Super Duty (F-250/F-350/F-450) or Toyota Tundra in Australia?
The safe, legal and warranty-friendly path is to:
- Choose springs, shocks and geometry correction (UCAs, radius arms, etc.) for your actual load and tyres
- Recover correct steering geometry with a proper alignment
- Verify and adjust ADAS (radar, camera, parking sensors) and headlight aim
- Document everything at handover
Australia uses VSB 14 / NCOP as the national engineering baseline, and then each state applies its own rules. Many guides treat ~50 mm suspension as the common “road-legal” benchmark, with some jurisdictions allowing ~75 mm combined (for example 50 mm suspension + 25 mm tyre radius increase) on certain vehicles. You must confirm the current rules in your home state before booking.
We build and document lift, tyre, towing and touring setups for these US full-size trucks — including Silverado 2500 HD and Sierra 2500 HD heavy tow rigs — for customers Australia-wide. We supply alignment sheets and ADAS checks with every build.
Why lift kits change how your truck behaves
A lift is not “just some springs”. On big American pickups it changes how the whole vehicle behaves at highway speed, with a caravan or trailer behind it.
- Steering geometry:
Caster, camber and toe all move when the front comes up. Too little caster = vague on-centre feel and tramlining. This is especially noticeable on F-150 and RAM 1500 when towing. - Roll centre & weight transfer:
Higher centre of gravity changes braking stability and cornering balance — important when you’re hauling a caravan or fifth-wheel with a Silverado 2500 HD / Sierra 2500 HD. - Driveline angles:
IFS and heavy-duty platforms push CV and propshaft angles steeper with height. Poor angles = vibration, heat and premature wear. - Headlight aim & ADAS:
Lifting alters headlight aim and sensor “view”. Front radar, cameras and park sensors (common on Silverado/Sierra and Super Duty) may now “look” at bull bars, pre-runner bars or light bars instead of the road. You must verify and adjust. - Tyre clearance:
Bigger diameter and different offset affect bump and lock-to-lock clearance, and how much tyre sticks out past the guards. On RAM 1500 and Silverado 1500 you’re often trimming liners / crash-bar areas if you’re chasing 35s.
What’s legal (use this to triage, then confirm locally)
National baseline: Australia relies on VSB 14 / NCOP for light-vehicle modifications. Use it with the current state process when considering that you will do your pickup truck. Infrastructure & Transport Dept.
State quick-reference (always check the latest page before making a decision):
You always pair that with the current state process before saying “you’re legal”.
Queensland (TMR / QCOP):
Queensland runs LS codes under QCOP. LS9 (design) and LS10 (certification) are what you fall into for higher lifts. TMR guidance and QCOP documents spell out when ~50 mm suspension can be treated as a basic (no-cert) mod and when combinations (suspension + tyres + blocks) need certification. There’s also an LS9 “High Lift” pathway (up to 150 mm) that’s design-certified. Industry summaries often quote ~75 mm combined on certain ESC-equipped vehicles.
New South Wales (TfNSW):
NSW publishes the Light Vehicle Modifications Manual – Suspension & Ride Height. That manual says what changes require VSCCS certification and what’s considered basic. You have to refer to the latest version because this is where NSW gets very specific.
Victoria (VicRoads / DoT):
VSI 8 – Guide to modification for motor vehicles – says you must maintain ADR compliance. It also explains when you need an engineering sign-off. For anything beyond mild height/tyre changes, you treat it as case-by-case with VSI 8 plus VSB 14.
South Australia (DIT):
Bigger suspension/ride height changes usually trigger an engineer signatory. DIT may require a Certificate of Exemption (COE) and a Statement of Requirements (SOR).
Western Australia (DoT):
WA groups mods into Minor / Simple / Complex. “Complex” lifts (significant height, tyre diameter jumps, steering geometry changes) need engineering approval through Vehicle Safety & Standards.
Tasmania (Transport Services):
Significant suspension/tyre mods are inspected and signed off by an Approved Vehicle Certifier through AVCAIS.
Northern Territory (MVR):
In the NT, MVR approval is required for major modifications. Big lifts or tyre changes can be referred to the Technical Advisory Committee (TAC). NT relies on VSB 14 for the underlying technical standard.
Important:
Transport ministers agreed in 2024 to update VSB 14 and work toward more consistent national rules. That means the “what’s allowed” numbers can shift.
Warranty & insurance: how we protect your position
A lift kit does change the engineering and geometry of a pickup truck so it is vital that the organisation fitting the lift kit truly understands the engineering of the vehicle and how the vehicle was converted. A key strength of Autogroup International is that we actually convert vehicles to right hand drive and have a team of over 30+ engineers – so we truly understand the impact.
This is where we separate ourselves from backyard lift installs and “4-inch Insta builds”.
- Causation, not automatic cancellation:
A lift kit doesn’t instantly void your warranty. The real question is: did something fail because of the lift, or because it was fitted badly? We build in a way that’s defensible. - Handover pack (Australia-wide):
Every RAM, Silverado 1500, Silverado 2500 HD, Sierra 1500, Sierra 2500 HD, F-150, Super Duty, and Tundra we build gets a documented pack:- Parts list
- Torque card
- Alignment sheet (before/after numbers + our target ranges)
- Headlight aim check
- ADAS / radar / camera functional check
- Re-torque / inspection schedule
- Insurance comfort:
Insurers care about two things: Is it roadworthy and compliant in your home state, and can you prove it was installed professionally and safely? Our documentation answers both.
If someone asks for a 4–6″ daily-driven “show truck” with 37s and no paperwork, we’ll either map out an engineered pathway or we’ll say “no”. That protects them and protects us.
Platform watch-outs (US full-size trucks in Australia)
Here’s what consistently comes up on real customer vehicles. This applies whether you’re in Victoria, Queensland, WA, NSW, SA, TAS or NT – people transport these trucks to us from all over Australia.
RAM 1500 (DT) / RAM 2500+
- Past ~2–2.5″, upper control arms and knuckle geometry matter to recover caster and ball-joint angles.
- Many owners chase ~35″ tyres, but 35s are not “bolt-on”. You’re often trimming inner liners and managing crash-bar clearance (especially on RAM 1500).
- RAM HD / RAM 2500-style platforms start moving into heavy towing and load-carriage, so you’re thinking about driveline angles and rear spring rate, not just front height.
Chevrolet Silverado 1500 / GMC Sierra 1500
- Lift + tyres + a front bar changes radar, parking sensors and camera visibility.
- After fitting a pre-runner bar or bull bar plus suspension, we re-check ADAS, parking sensors and front camera views.
- Offset and poke matter: extreme negative offset might look “tough” but it can ruin steering feel and push tread outside the guards.
Chevrolet Silverado 2500 HD / GMC Sierra 2500 HD
- These heavy-duty (HD) trucks are serious tow rigs for caravans, goosenecks, toolbodies and heavy touring setups.
- Geometry correction (radius arms, track bar brackets, steering correction, etc.) is usually built into proper HD kits rather than a simple bolt-on UCA.
- Owners often aim for 35–37″ LT load-rated tyres. Bigger rolling mass = different braking demand, steering load, and sometimes cooling considerations for long-distance towing.
- On a Silverado 2500 HD / Sierra 2500 HD, the lift conversation is never just “stance”. It’s towing stability at 100–110 km/h, brake control under load, and how that package will be viewed by police/inspectors when you cross into another state.
Ford F-150
- The F-150 is extremely sensitive to caster. “In spec” caster is not always “nice to drive”.
- We tune caster for highway stability and return-to-centre, especially with boats, jet skis or enclosed trailers.
Ford Super Duty (F-250 / F-350 / F-450)
- Similar story to Silverado/Sierra 2500 HD: this platform is built for towing and heavy work.
- We are managing driveline angles, steering geometry, brake demand and ADAS calibration — not only height.
Toyota Tundra (’22+)
- Tundra’s hybrid packaging puts heat, wiring looms and sensors in tight spots.
- When you lift it and add a bull bar or pre-runner bar, you have to think about loom routing, heat management and radar/camera angles.
- We test ADAS and camera views before handover.
Brand ecosystem (broad and practical) — how to choose well
There is no single “best brand”. We pick the system that fits how you actually use your truck and how it will be interpreted by compliance in your home state.
Here’s how we frame the main families for Australia-wide customers:
- FOX
2.0 through 2.5 Performance / Performance Elite / Factory Race. Strong control and heat management on corrugations and towing. Good match for Silverado 1500, RAM 1500, F-150, Tundra, and also higher-spec towing setups on Silverado 2500 HD, Sierra 2500 HD and Super Duty. - ICON Vehicle Dynamics
2.5 CDCV coilovers with billet UCAs (Delta Joint), popular on GM 1500 and late F-150. Adjustable compression gives you fine control for daily vs loaded touring. - King Shocks
Rebuildable 2.0 / 2.5 / 3.0 coilover and bypass options. Ideal for people who actually punish their trucks, run heavy constant loads, or spend long stretches on corrugated roads. - Bilstein
6112 (big-bore front) + 5160 (remote-res rear). A proven daily/touring combination for people who tow and road-trip but aren’t chasing a hardcore desert setup. - Carli Suspension
Built specifically for RAM HD and Ford Super Duty platforms. These aren’t cosmetic spacers; they’re engineered ride/handling packages for big towing, heavy front axles and long-distance comfort. - Zone Offroad
Lift/level kits covering RAM, Silverado/Sierra 1500, F-150, Tundra and so on. Useful entry point where budget matters but you still want a matched system instead of a random stack of spacers. - Lovells (GVM)
Certified GVM upgrades (pre- and post-reg pathways). This matters when the story is payload and legally towing heavy — e.g. Silverado 2500 HD / Sierra 2500 HD / Super Duty / RAM 2500+ doing serious caravan or work duty. GVM is its own engineered pathway, not just “a lift”.
Quick chooser
- Daily / Touring: Bilstein 6112/5160; FOX 2.0 / 2.5
- Towing / Corrugations: FOX 2.5 / Performance Elite; ICON 2.5 CDCV; King 2.5 with reservoir
- Heavy-Duty (RAM HD, Silverado 2500 HD, Sierra 2500 HD, Super Duty): Carli; high-spec FOX or King
- Budget / Entry: Zone Offroad (still needs ESC/ADR and tyre/track checks)
- Payload / GVM: Lovells GVM + tuned shocks/springs around that new legal payload
We always match damping, travel, spring rate and heat capacity to what you actually do, not just what “looks tall on Instagram.”
Lift Kit Selection Table (for Australia-wide customers)
This table is a planning tool, not a guarantee. We use it with owners from Victoria, Queensland, Western Australia, New South Wales, South Australia, Tasmania and the Northern Territory.
Before we lock in a package, we confirm:
- The legal/mod pathway in your home state
- Tyre/offset/track so it’s safe, roadworthy and insurable — not just “looks tough”
- Steering geometry and driveline angles so it tows straight at highway speed with a van on the back
- ADAS, headlights and radar/camera performance so you keep safety systems and towing aids working
| Platform | Typical Use Case | Target Lift Range | UCA / Front Geometry Correction Needed? | Shock / Suspension Families to Shortlist | Tyre Sizes Commonly Attempted | Track / Offset Notes |
|---|---|---|---|---|---|---|
| RAM 1500 (DT) | Daily driver + towing (caravan / boat) | +2.0″ to +3.0–3.5″ | Often yes at ~2.5″+ to recover caster | FOX 2.0 / 2.5; Bilstein 6112/5160; ICON 2.5; Zone Offroad; Carli (mainly HD on 2500/3500) | 33–35″ LT all-terrain / mud-terrain | 35s usually need inner clearance work and correct offset to keep tread under guards |
| Chevrolet Silverado 1500 / GMC Sierra 1500 | Touring + light off-road + front protection (bull bar / pre-runner / winch) | +2.0″ to +3.0–3.5″ | Commonly yes above ~2.5″ | FOX 2.5 / Performance Elite; ICON 2.5 CDCV (billet UCAs); King 2.5; Zone Offroad | 33–35″ A/T or hybrid terrain | Aggressive offset can block radar/camera and upset parking sensors — must be checked |
| Chevrolet Silverado 2500 / GMC Sierra 2500 (HD) | Heavy towing, fifth-wheel / caravan / work use | +2.0″ to +3.0–3.5″+ (HD-style kits with corrected steering/geometry) | Usually addressed in the HD kit rather than bolt-on UCAs | FOX 2.5 / heavy-duty reservoir shocks; King 2.5+; heavy-rate coil/leaf or coilover upgrade sets | 35–37″ LT load-rated towing tyres | Heavier tyres add rotating mass and braking load — match tow setup and brake controller |
| Ford F-150 | Daily + towing + boat / toy hauling | +2.0″ to +2.5–3.0″ | Often yes above ~2.5″ (caster sensitive) | FOX 2.0 / 2.5; Bilstein 6112/5160; ICON 2.5 CDCV; Zone Offroad | 33–34.5″ A/T or highway-terrain towing tyre | Too much poke (big negative offset) hurts steering feel and can stick tyres past guards |
| Ford Super Duty (F-250 / F-350 / F-450) | Heavy towing, highway stability, mining / remote work | +2.0″ to +3.0–3.5″+ (HD kits incl. radius arms / 4-link options) | Usually built into proper HD kits | Carli Suspension (Pintop / Commuter etc.); FOX 2.5 / Factory Race; King 2.5+ | 35–37″ LT load-rated towing tyres | Big tyres = more brake demand; confirm braking, GVM, tow control, and cooling |
| Toyota Tundra (’22+) | Touring + canopy / RTT + weekend towing | +2.0″ to +2.5–3.0″ | Often yes above ~2.0–2.5″ (loom / sensor angles) | FOX 2.0 / 2.5; ICON 2.5 CDCV; King 2.5; Zone Offroad | 33–34″ load-rated A/T | Watch radar / camera angle and loom heat near the front bar — test ADAS after fitment |
Installation checklist (used for every Australia-wide job)
We follow the same structured process whether you’re local or you’ve come to us from interstate.
- Baseline:
Measure ride height, read alignment, check headlight aim, scan for any DTCs. - Install:
Fit springs/shocks/UCAs or HD link/radius arm components per the kit. Torque everything at ride height (not hanging). - Clearance:
Full bump travel and lock-to-lock with your actual wheels/tyres (including 35s / 37s on Silverado 2500 HD, Sierra 2500 HD, Super Duty etc.). - Alignment:
Set caster/camber/toe to target values and road-test for stability and return-to-centre. - Headlight aim:
Adjust after lift so you’re not dazzling traffic. - ADAS:
Check radar, camera, parking sensors. Re-aim or calibrate if required, then road-test. This step is critical for Silverado/Sierra, Super Duty, and Tundra. - Handover pack:
Alignment sheet, ADAS/headlight notes, torque card, re-torque schedule, tyre pressure / towing pressure guidance.
That pack protects you if you’re pulled over, questioned by an insurer, or challenged by a dealer.

How high can I go without engineering?
It depends on your state. Queensland’s QCOP and LS codes outline what’s considered a “basic” lift and when you fall into LS9/LS10 certification (including an LS9 High Lift design path). New South Wales uses the Suspension & Ride Height manual and VSCCS sign-off. Those thresholds can change, so we confirm them the day we book you.
Will a lift kit void my warranty?
Not automatically. The test is causation. If a failure is caused by bad geometry, wrong parts or poor install, YES. If we’ve engineered it, aligned it, verified ADAS and lights, and documented it, you’re in a much stronger position.
Do I need UCAs for a 2–3.5″ IFS lift?
On most IFS trucks (RAM 1500 DT, Silverado 1500, Sierra 1500, F-150, Tundra), yes once you’re past ~2–2.5″. UCAs help recover caster and ball-joint angles so it actually drives properly. On HD platforms like Silverado 2500 HD / Sierra 2500 HD / Super Duty, correction is usually built into the heavy-duty kit (radius arms, track bar brackets, etc.) rather than bolt-on UCAs
Can I run 35s or 37s?
35s are common targets on RAM 1500, Silverado 1500, Sierra 1500 and F-150 at around the ~3″ lift mark, but they usually need offset control and trimming.
35s and even 37s show up on Silverado 2500 HD, Sierra 2500 HD and Super Duty builds used for towing and remote work — but that’s now a full package: brake demand, gearing feel, steering load, cooling, plus compliance. We’ll walk you through that before we say yes.
Do you work with interstate customers?
Yes. Our clients work with Autogroup International direclty – no ‘partners or dealers’. We build and document RAM, Silverado 1500/2500 HD, Sierra 1500/2500 HD, F-150, Super Duty and Tundra packages for customers Australia-wide. People travel to us from Victoria, Queensland, WA, NSW, SA, TAS and NT because they want it done once, properly, with proof.
