A Formula 4x4 N90 Hilux lift kit gives the N90 the height, control and load capacity the factory setup lacks, built for harsh Australian off road with OE comfort in mind. Choose a 2 inch ReadyStrut kit, a 2 to 3 inch adjustable remote reservoir kit, or a certified 3571kg GVM upgrade, all backed by a 5 year warranty.
The new N90 Hilux is a capable ute out of the box, until you load it. Add a bar, a winch, a canopy and touring weight and the factory springs sag, the shocks fade on corrugations and the front end wallows. Formula 4x4 builds suspension to fix exactly that. Our N90 lift kit range is engineered for real Australian conditions, from beach sand to outback corrugations, and paired with SuperPro geometry parts it keeps the ute sitting right, steering true and carrying weight without complaint.
Toyota springs the N90 for a standard weight on sealed roads. That is fine on the highway but is nowhere near enough once the ute is set up for touring or work. The rear squats under a canopy and drawers, the shocks overheat and fade on long dirt roads, and the front dives and rolls when you carry weight. You feel it as a vague, bouncy, tiring ride, and it costs you control where you need it most.
A Formula 4x4 upgrade rebuilds the way the ute behaves. Matched springs restore and hold height with your gear fitted, our shocks keep the tyres planted for grip and braking, and the ride stays composed loaded rather than crashing over bumps. You also gain clearance for larger tyres and rougher tracks. The result is a ute that tours better fully loaded than a standard N90 does empty.
The takeaway: once you add weight or leave the blacktop, a matched Formula 4x4 kit is the upgrade that changes how the N90 drives most.
The best lift kit is the one matched to your load and your terrain, not the tallest one on the shelf. Formula 4x4 covers three clear choices for the N90.
Start with a rear block spacer kit if you only need a small, low cost rear lift for towing. Step up to the 2 inch 50mm ReadyStrut kit for the sweet spot most tourers want: a 50mm lift with a height adjustable front strut so you can dial the ride height to suit your bar and winch. For maximum height, travel and heat control, the 2 inch to 3 inch adjustable kit runs remote reservoir shocks that resist fade on long corrugated tracks.
Every kit is designed as a matched system, springs and shocks tuned together, so you avoid the harsh, unbalanced ride you get from mixing parts. Match the front spring rate to your accessory load and the kit holds its height instead of sagging back down.
The takeaway: pick the lift by how you load and drive the N90, from a simple 2 inch ReadyStrut kit to a remote reservoir setup for serious touring.
A ReadyStrut is a Formula 4x4 front strut assembly that arrives ready to bolt in, with the coil and shock preassembled and set for a lift. The height adjustable versions let you fine tune the front ride height, which matters because every N90 carries a different front load. A bare ute and one running a steel bar plus a winch need different front spring preload to sit at the same height.
Height adjustability means one kit can be set correctly for your build rather than lifting a fixed amount regardless of what you have bolted on. It also makes it easy to level the ute and to correct for uneven side to side height. Fitted and set properly, a ReadyStrut front end gives you the lift you paid for and keeps it there.
The takeaway: a height adjustable ReadyStrut lets you tune the front to your exact accessory load, so the N90 sits level and holds its height.
Shocks control the springs and manage heat, and heat is what kills a shock on a long dirt road. A standard twin tube shock is more than enough for road use and light dirt. Push into sustained corrugations, sand and high speed touring and the oil heats up, the shock fades, and the ride goes vague right when you want control.
Remote reservoir shocks add a separate reservoir of oil and gas, which increases oil volume and cooling. That keeps damping consistent when a standard shock would fade. Formula 4x4's adjustable F4R rear shock kit and the 2 to 3 inch adjustable kit use this design for owners who spend real time off road. If your N90 mostly commutes and tours light, a standard kit is the sensible choice. If it lives on corrugations, the remote reservoir option is the one that stays composed.
The takeaway: standard shocks suit road and light dirt; step up to remote reservoir if your N90 sees sustained corrugations, sand or high speed touring.
If your N90 regularly runs at or over its factory GVM, yes. GVM is the legal maximum the fully loaded vehicle can weigh, and a touring or work Hilux hits it quickly once you add a bar, winch, canopy, drawers, fuel, water, passengers and a load. Overloading is illegal, hard on the ute and can affect insurance.
Formula 4x4's 3571kg GVM upgrade lifts the legal limit with an engineered spring and shock package tuned for the heavier target weight. It comes in fixed and height adjustable versions and is supplied ADR compliant with the certification and compliance plate required to keep the ute road legal. Because the kit is sprung and valved for the loaded weight, the ute also rides and controls properly loaded rather than being set up for a weight it never carries.
The takeaway: if the N90 lives near or over its limit, a certified Formula 4x4 GVM upgrade is the legal, better riding answer to carrying real weight.
Lift the front of the N90 and the geometry changes. Caster drops, camber shifts and the factory upper control arms can bind at full droop. Uncorrected, that means twitchy steering, uneven tyre wear and less articulation. This is the step people skip, and it is the one that protects your new tyres and your steering feel.
SuperPro is the engineering partner in the Formula 4x4 range for exactly this. SuperPro adjustable upper control arms restore caster and camber, add clearance for the lift and use heavy duty ball joints built for off road loads. Where a full arm is not needed, a camber bolt kit and alignment correction bushes bring the numbers back into range, and heavy duty adjustable sway bar links suit the taller ride height.
The takeaway: a lift changes your front geometry, so SuperPro caster and camber correction is part of doing an N90 lift properly.
The N90 carries its load on rear leaf springs, and that is where a loaded ute sags first. Formula 4x4 and SuperPro cover the rear with heavier constant load options and the wear parts that keep it controlled: complete heavy duty leaf spring bush kits, greasable shackle and pin kits, and rear eye bushes rated for hard use. Fresh, quality bushes keep the axle located and stop the rear feeling loose under load.
Bigger tyres and higher speeds on dirt can also introduce steering shake through the front end. A Formula 4x4 steering damper settles that down and takes the edge off corrugations transmitted to the wheel. Together these parts keep a loaded, lifted N90 feeling planted rather than nervous.
The takeaway: match the rear to your load and keep the bushes fresh, and add a steering damper if you run larger tyres on rough roads.

The takeaway: Formula 4x4 pairs a matched, adjustable kit with SuperPro geometry parts and a 5 year warranty, which is what separates a setup engineered for the load from a cheap lift.
Cost depends on the kit and whether you add geometry correction and fitment. A rear block spacer is the cheapest entry, a 2 inch ReadyStrut kit sits in the middle, and a 2 to 3 inch adjustable remote reservoir kit is the premium option. Add SuperPro upper control arms, sway bar links or a steering damper and the price rises with the capability. Every Formula 4x4 product page shows the part price and the fully installed price, so you can weigh up buying the kit alone against having it fitted.
On legality, a 2 inch lift on the N90 is generally within the rules when it is fitted and set up correctly, though the exact limits and certification requirements vary by state. Getting the kit fitted matters here for two reasons: the ute is aligned so it stays compliant and wears tyres evenly, and a fitter can advise on your state's rules before you go taller. Buying the cheapest kit and bolting it on at home is where owners get caught out on both ride quality and compliance. You can have your kit professionally installed at Fulcrum Suspensions, which fits Formula 4x4 kits through its national workshop network of over 200 partners and shows the installed price alongside each product.
The takeaway: budget for the kit plus any correction parts and fitment, and have it set up properly so the lift is both legal and correctly aligned.
