Product Overview

This heavy-duty suspension conversion provides a robust, cost-effective alternative to the factory AHC hydraulic system which is prone to wear and expensive to repair. The kit suits demanding use such as towing, off-road and commercial payloads by offering improved vehicle control and stability under load. While the unladen ride may feel firmer due to the upgraded components, the enhanced durability and resistance to failure provide lasting value.

Technology & Materials

The kit uses traditional mechanical suspension components including torsion bars and coil springs combined with heavy-duty shock absorbers designed to withstand rigorous load conditions. Reinforced torsion bar mounting plates increase strength and durability to meet heavy load demands.

Installation & Compatibility

The kit includes all necessary components to fully replace the factory AHC suspension system, including instructions to disable AHC warning lights. Components bolt into existing mounting points, and no cutting or welding is stated. Professional wheel alignment after installation is recommended.

This kit is optimised for heavy-duty use such as towing and carrying constant loads rather than comfort-focused use.
