4"-6" Lift Front Caster 5° Castor Plate – Toyota LandCruiser 80 105 Series (1991-ON)
Correct dangerous negative caster, vague steering, tramlining, wandering and poor return-to-centre feel on your lifted Toyota LandCruiser 80 Series (FZJ80/HDJ80/HZJ80/HDJ81 1991-1997) or 105 Series (HZJ105 1998-2007) with this 5° positive caster correction plate from Machter Auto Parts. Designed specifically for 4"-6" lift kits, these plates restore factory-like steering geometry, sharpen turn-in, improve high-speed stability and reduce tyre wear – essential for lifted rigs running 33–35" tyres, towing or driving fast dirt/gravel in Australia.
Key Features
- Sold as a pair (left + right front caster plates) – adds ~5° positive caster correction
- Direct fit for Toyota LandCruiser 80 Series (1991-1997) and 105 Series (1998-2007) with solid front axle and 4"-6" lift
- High-strength 10mm steel plates – laser-cut, fully welded gussets and powder-coated black
- Pre-drilled & slotted holes – bolts between upper control arm and chassis bracket (no drilling required)
- Reinforced design – handles heavy loads, rock crawling and high-speed corrugations without flex
- Compatible with factory or aftermarket upper control arms, shocks and coil springs
Benefits
- Restores positive caster – eliminates vague steering & tramlining, improves self-centring
- Sharper turn-in & stability – better high-speed confidence and reduced driver fatigue
- Reduces tyre wear – even contact patch and correct alignment angles
- Fixes lift-related handling issues – common complaint on 4"+ lifted 80/105 Series
- Stronger than stock setup – built for real off-road abuse and heavy towing
- Essential mod for lifted Cruisers – keeps your 80/105 Series driving straight and safe
Fitment Notes
- Suitable for Toyota LandCruiser 80 Series (1991-1997) and 105 Series (1998-2007) with 4"-6" lift kits
- Professional installation recommended – torque bolts to spec, re-align vehicle (caster/camber/toe) and test drive
- Check your lift height & control arm type – plates suit most 4-6" coil lift setups
- Pair with adjustable upper control arms or panhard rod for full geometry correction
- Alignment required after install – critical for safety and tyre life

Frequently Asked Questions
What does a castor plate kit do for a lifted 80/105 Series?
When you lift an 80 or 105 Series, the front axle rotates, reducing the caster angle. This makes the steering feel "twitchy" or "light" and causes the vehicle to wander on the road. Castor plates rotate the axle housing back to the correct angle, restoring the factory steering geometry, tracking stability, and self-centering feel.
Why choose plates over offset bushings?
While offset radius arm bushings are a common solution, they can restrict suspension articulation by binding up inside the radius arm. Castor plates are a more robust, "hard" mounting solution that maintains the correct geometry without compromising the range of motion of your radius arms, ensuring your off-road articulation isn't affected.
Is this kit suitable for my 4 to 6-inch lift?
Yes, these plates are engineered specifically for the 4 to 6-inch lift range. At these heights, the loss of caster is significant, and a 5-degree correction is essential to bring your steering performance back into a safe and comfortable range for highway driving.
How is the installation performed?
Installation requires removing the front radius arms at the chassis side. The plates are then fitted to the chassis mounting points to change the arm angle. Because this involves steering and suspension components, we strongly recommend having these installed by a professional, followed by a professional wheel alignment to ensure your toe-in and camber are also set correctly for the new geometry.
Will this affect my pinion angle?
Correcting caster by rotating the axle housing *does* slightly tilt the front pinion angle. For most 4–6 inch lifts, this correction is necessary for steering safety. However, if you experience new drivetrain vibrations after installation, you may need to look into a double-cardan front driveshaft to accommodate the new pinion angle.
