Air Spring

Each air spring comprises a top cap assembly, an air bag and a base piston. The air bag is attached to the top cap and the piston with crimp rings. The air bag is made from a flexible rubber material which allows the sleeve to roll up and down the air spring piston as the vehicle changes height. The top cap assembly comprises the plastic top cap with a spigot which protrudes through a hole in the subframe. This spigot includes a timing feature to ensure the air spring is in the correct orientation and is attached to the subframe with a spring clip. On the side of the top cap is a connector which allows for the attachment of the air pipe from the valve block. The piston is made from plastic and is shaped to allow the air bag to roll over its outer diameter. The base of the piston has a spigot with an integral clip to locate into the lower wishbone.

The air springs are located inboard of the shock absorbers and are retained between the subframe and the lower wishbone.

Coil Spring 

Coil springs and dampers have been selected to deliver comfort in both on and off road driving conditions. The rear suspension design has been optimised with a specially developed secondary spring, which helps to deliver optimum ride and stability when the vehicle is heavily laden. Mounted inside the coil spring at the top of the damper strut, the rubber spring aid has a complex design which acts as a supplementary spring/damper as the coil spring approaches the limit of its travel.
