Product Overview

The Pedders kit converts from the factory hydraulic and pressurised sphere AHC system to a conventional coil spring and torsion bar suspension for FZJ & UZJ100 IFS LandCruiser models. This addresses common issues with ageing hydraulic components, reducing maintenance costs and improving reliability over time.

Ride height and comfort may vary depending on the original AHC system condition. The kit includes front torsion bars, reinforcement plates, rear coil springs, shocks, and instructions for disabling the AHC system to prevent dash warnings. Variants range from standard conversion to heavy-duty kits with lift and upgraded shocks for towing and off-road use.

Technology & Materials

The kit replaces the complex hydraulic AHC system with durable conventional mechanical suspension components, including coil springs, torsion bars, and shock absorbers, designed to work together as a matched system for reliable performance.

Installation & Compatibility

The kit includes all necessary components for a full conversion and instructions to disable the AHC system. It is designed for bolt-in installation for FZJ & UZJ100 IFS models, with no mention of cutting or welding. Professional wheel alignment is recommended after installation to optimise handling and tyre wear.

This kit suits unladen or lightly loaded vehicles as a comfort-focused replacement, with other variants available for heavier loads and towing.
