Product Overview

The Pedders conversion kit provides a reliable alternative to the complex and aging hydraulic AHC suspension system by using traditional coil springs, torsion bars and shocks. This results in a more predictable ride quality and eases maintenance and repairs.

Available in multiple variants, the kit accommodates unladen vehicles, light to moderate towing, and heavy-duty load carrying with options for rear lift springs and heavy-duty shocks. This makes it suitable for a range of use cases from daily driving to demanding load and towing conditions.

Technology & Materials

The kit includes front torsion bars, reinforced torsion bar mounts, rear coil springs and matching shock absorbers for front and rear. It is designed as a fully integrated system optimised to replace the AHC components.

Installation & Compatibility

The kit contains all necessary components including torsion bars, reinforcement plates, coil springs and shocks. Instructions are provided to disable the AHC system to prevent dashboard warnings. The bolt-in nature of the kit simplifies installation. A professional wheel alignment is recommended after fitting.

Options are provided to suit comfort-focused standard use, lifted fitments and heavy-duty towing or load carrying applications.
