Key Features

• Complete kit for AHC removal and conversion
• Cost-effective alternative to AHC system repairs
• All components engineered to work together as a system
• Variants available to suit different usage requirements
• Backed by a 2-Year / 25,000-Mile Warranty

Product Overview

The Pedders conversion kit disables the ageing hydraulic AHC spheres and replaces them with conventional suspension components, including front torsion bars and rear coil springs. This results in a system that is less prone to expensive failures while sustaining vehicle height and performance. Different variants cater to typical unladen use, moderate towing, and heavy-duty load carrying, ensuring the suspension is optimised for the driver's needs.

The kit fitted with raised rear springs adds approximately 2 inches of lift, improving clearance and load capacity. Ride comfort may be firmer than the original AHC comfort mode and can vary due to the condition of the original system and vehicle load. The kit suits both daily driving and off-road applications where simplicity and durability are priorities.

Technology & Materials

The kit uses conventional coil springs and torsion bars to replace the hydraulic AHC system. Front torsion bars come with reinforcing plates for durability. The rear coil springs are selected to cope with load variations and maintain vehicle stance. Heavy-duty variants include specialised shock absorbers designed to handle increased weight and towing demands.

Installation & Compatibility

The kit includes all necessary components for a full replacement of the AHC system, with instructions for disabling the AHC to avoid dashboard warnings. It fits LandCruiser HD FZJ & UZJ100 IFS variants and is compatible with all wheel sizes. Vehicle height measurements are based on 16-inch wheels. Professional wheel alignment is recommended post-installation to ensure proper setup.

The kit is suitable for drivers seeking a durable, maintenance-friendly suspension setup with options tailored for light or heavy-duty use including towing and load carrying.
