Adjustable Rear Upper & Lower Trailing Control Arms – Toyota LandCruiser 80 105 Series (2"+ Lift)
Fix rear axle wrap, poor handling, bump steer, tyre rub or wandering on your lifted Toyota LandCruiser 80 Series (HDJ80/HZJ80/HDJ81) or 105 Series (HZJ105) with these fully adjustable rear upper & lower trailing control arms. Designed specifically for 2" lift and above, they restore correct pinion angle, centre the axle, improve articulation and eliminate driveline vibrations – perfect for work tourers, off-road builds or 4x4s running 33–35" tyres after suspension upgrades in Australia.
Key Features
- Complete set: 2x adjustable rear upper trailing arms + 2x adjustable rear lower trailing arms
- Direct fit for Toyota LandCruiser 80 Series (1990-1997) and 105 Series (1998-2007) with 2" lift or higher
- Heavy-duty 4130 chromoly or DOM steel tubing – thick wall for maximum strength under load
- High-angle greasable heim joints or polyurethane bushings – allow full articulation without binding
- Threaded adjusters with lock nuts – fine-tune length (±2–3 inches typical) to correct pinion angle and axle centring
- Powder-coated or zinc-plated finish – corrosion-resistant for mud, salt and wet conditions
- Pre-drilled & welded end fittings – bolt-on with factory or aftermarket brackets
Benefits
- Eliminates axle wrap & driveline vibration – smoother power delivery and less U-joint stress
- Restores correct pinion angle – reduces vibrations at highway speeds and improves tyre life
- Centres rear axle under lift – prevents rubbing, improves stability and handling
- Better articulation & off-road performance – more flex on uneven tracks without binding
- Stronger than factory arms – handles heavy towing, rock crawling or high-speed corrugations
- Essential for lifted 80/105 Series – fixes common lift-related handling issues
Fitment Notes
- Suitable for Toyota LandCruiser 80 Series (HDJ80/HZJ80/HDJ81 1990-1997) and 105 Series (HZJ105 1998-2007) with 2" lift or more
- Professional installation recommended – measure pinion angle before/after, torque heim joints/bolts to spec, and re-align vehicle
- Grease joints regularly – check for play every 10,000 km
- Pair with adjustable panhard rod or track bar for full rear geometry correction on lifted rigs
- Confirm your lift height and axle setup – may require custom brackets on extreme lifts

Frequently Asked Questions
Why are adjustable rear trailing arms necessary on lifted LandCruisers?
When you install a suspension lift kit of 2 inches or higher, the increased ride height pulls the rear axle forward and alters the pinion angle. Upgrading to adjustable trailing arms allows you to correct the axle's fore-and-aft position within the wheel arch and reset the rear differential pinion angle layout. This precision realignment is vital to prevent driveline vibrations and premature universal joint wear.
Which specific LandCruiser models do these rear control arms fit?
This heavy-duty suspension upgrade is engineered specifically to suit live-axle coil-sprung wagon variations. It is a direct physical replacement for all Toyota LandCruiser 80 Series (FJ80, FZJ80, HDJ80, HZJ80) and 105 Series (FZJ105, HZJ105) models running suspension setups lifted from 2 inches up to extreme heights.
What material and structural layout are used to build these trailing arms?
These arms are constructed from thick, heavy-wall high-tensile structural steel tubing, making them vastly stronger than the easily bent factory tin-style equivalents. They feature an integrated fine-thread on-vehicle adjustment turnbuckle secured by robust locking nuts, combined with high-flexion bushes designed to maximize wheel articulation while absorbing harsh outback corrugations.
Does this kit replace both the upper and lower rear suspension links?
Yes, this comprehensive suspension kit includes both the upper adjustable trailing arms and the lower heavy-duty control arms to completely overhaul your rear axle's 5-link geometry. Overhauling both levels together guarantees total control over axle placement, straight tracking, and stable rear-end handling performance under heavy touring or towing loads.
What critical steps must be followed during installation and adjustment?
Proper execution during fitting is essential for alignment accuracy and safety. Always adjust the arms to equal lengths on both sides to prevent the axle from tracking crookedly. Final tightening of the main chassis and axle mounting bolts must be carried out while the vehicle is sitting flat on its wheels under full kerb weight—tightening them while the suspension is hanging down will bind the bushes and cause rapid premature failure.
