unit and to prevent the ingress of dirt and moisture. The seal also incorporates a wiper to keep the rod clean.
Air Spring
The air spring comprises an aluminium restraining cylinder, top mount, spring aid, air sleeve and an inner support sleeve.
The air sleeve 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 air sleeve is attached to the restraining cylinder and support sleeve by crimp rings which
provide an air tight seal. The support sleeve contains a seal carrier which has two O-rings sealing the support sleeve and
two O-rings sealing to the damper body. The top of the air sleeve is crimped to the top mount which attaches to the body
inner wing with 3 integral studs and self-locking nuts.
A spring aid is fitted to the damper rod and prevents the top mount contacting the top of the damper during full
suspension compression and assists the suspension tune. The lower end of the air spring is located over the damper
body and seats on a fabricated seat on the damper body. The air sleeve is positively attached to the seat with a retaining
pin. The damper rod is located through a central hole in the top mount. The rod is threaded at its outer end. A self-locking
nut secures the air spring to the damper rod.
The top mount is an integral part of the air spring and is fitted with a bush and rebound washer which are located between
the top mount plate and the damper rod. The top mount is secured to the damper rod with a self-locking nut. The top
mount attaches to a housing on the chassis with 3 integral studs and self-locking nuts. The top mount also incorporates a
6 mm Voss air fitting which allows for the attachment of the air harness.
A gaitor is available as a dealer fit component. The gaitor is similar to the one fitted to the rear air damper module and is
available if a customer experiences dirt and debris becoming trapped between the air sleeve and the restraining cylinder
under certain terrain conditions.
