Product Overview

The Pedders Heavy Duty Variable Load Suspension Kit uses a rear airbag system combined with a pair of shocks while retaining the stock rear springs. This keeps the vehicle at standard height and maintains factory-like comfort during unladen driving. When carrying significant loads, the airbags can be inflated using an airline similar to that used for tyres, providing additional support and improving vehicle balance and handling under load. This kit is ideal for users who occasionally carry heavy loads but mostly drive without a load.

Technology & Materials

This kit features sintered iron piston shocks with a large 40mm bore for durability and effective damping. The airbags provide variable load support and work in conjunction with the standard rear springs to maintain standard height and ride comfort when unladen.

Installation & Compatibility

The included components replace the original rear suspension items with no additional vehicle modifications required. The kit bolts in directly and uses an airline for airbag inflation as needed. Professional wheel alignment after installation is recommended to optimise handling and tyre wear.

Suitable for occasional load carrying and towing with comfort maintained when unladen.
