Front End

The front suspension is designed to support the additional weight commonly added to a touring or work related accessories, such as bull bars, winches, batteries and other modifications. Heavy-duty front coil springs are matched with premium shock absorbers to improve ride quality, suspension control and wheel travel while maintaining correct ride height under load.

To maximise strength and reliability, the front suspension package also incorporates upgraded radius arms, steering correction components and extended brake lines, creating a complete system rather than just installing taller springs.

Radius Arm Options

Superior Engineering Radius Arms are designed to restore caster angle after lifting your LandCruiser while significantly increasing strength over the factory arms. Built to withstand harsh off-road conditions, they improve steering feel, directional stability and front suspension articulation.

You can also choose from a range of Superior Engineering Radius Arm options to suit your intended use, from Superior Steel Radius Arms through to Billet Radius Arms.

STEERING

Lifting a LandCruiser changes steering geometry, which can lead to bump steer, vague handling and increased component wear if left uncorrected. This kit includes a complete steering correction package featuring an upgraded drag link, tie rod, panhard rod and steering damper.

Working together, these components restore steering geometry, improve driver confidence and deliver more predictable handling both on the highway and when tackling challenging off-road terrain.

Shocks

A suspension package is only as good as its shock absorbers. Superior Engineering offers a range of premium shock options to suit different driving styles, from comfortable daily touring through to heavily loaded remote-area expeditions and serious off-road use.

Every shock option has been specifically valved to complement the supplied spring rates, providing excellent ride comfort, improved wheel control and consistent damping performance across a wide range of terrain.

Track Corrected Diamond Differential Housing & Axle Set

For customers wanting the ultimate drivetrain upgrade, this GVM package can also be paired with Superior Engineering's Track Corrected Chromoly Diamond Diff Housing. Designed to bring the rear wheel track out parallel with the front diff, this housing is the ultimate in functionality & strength - covered by a Lifetime Warranty against bending or cracking. OEM Diff Centre (Locked or Un-Locked) & OEM Brake Assembly compatible, load rated to 3,150kg and manufactured from 830MPA Chromoly Steel, this Diff Housing is the Strongest and best supported option on the market.

Diamond Diffs also come standard with 300m Axles manufactured by RCV in the United States, which are covered by a lifetime warranty against breaking. These axles are coupled with our 4340M Billet Drive Plates and topped off with Anodized Blue alloy axle caps etched with the Superior Engineering Logo.

Brakes

Increasing your vehicle's carrying capacity also places greater demands on the braking system. This kit includes extended front and rear brake lines, upgraded caliper lines, a brake booster upgrade and the Superior Engineering Handbrake Upgrade Kit.

Together, these components maintain safe braking performance throughout the increased suspension travel while improving brake pedal feel and ensuring the handbrake remains effective, even after the suspension lift. The result is a braking system engineered to match the increased capability of your upgraded LandCruiser.
