A common limitation of modern independent front suspension (IFS) 4WD vehicles is the narrow alignment adjustment range, which becomes critical when the vehicle is lifted more than 1 inch. Lifting often leads to insufficient caster and camber, ball joint binding, and contact between the upper control arm and the coilover strut. The Whiteline KTA301 fixed offset Upper Control Arm (UCA) set is engineered as a comprehensive solution for vehicles with 30mm to 70mm (1.2" to 2.75") of lift.

These arms utilize Whiteline’s proprietary GIIRO bushing technology, providing a maintenance-free, grease-free pivot point that offers superior articulation without the noise or harshness of traditional poly bushings. The fixed geometry corrects suspension sweep and restores essential alignment specs for improved high-speed stability and tire wear.

Vehicle Fitment

Fits 1991-1997 Toyota Land Cruiser Base models.

The ICON 4.6 Degree Caster Correction Kit is engineered to restore steering geometry and handling stability on lifted 80 Series Land Cruisers. When installing a suspension lift on a solid front axle vehicle, the axle housing rotates forward, which reduces positive caster. This often results in "wandering" steering, poor tracking, and a lack of return-to-center feel.

This kit provides 4.6 degrees of correction to rotate the axle back to a proper alignment specification, significantly improving high-speed stability and driver feedback. It is a necessary upgrade for any lifted Cruiser to ensure the vehicle remains predictable and safe on and off-road.

• Specifically designed for 1991-1997 Toyota Land Cruiser
• Provides 4.6 degrees of positive caster correction
• Restores factory-like steering tracking and stability
• Compensates for geometry changes caused by suspension lifts
• Manufacturer Part Number: 53008
