Shock Rebuilds

Just like most race car parts, a damper's internal moving parts are consumable items and need to be replaced at regular intervals to maintain its long-term life and maximise its performance. The shock shaft is coated with a microscopic layer of oil and this attracts dust. Over time some of this dust will get dragged inside the shock. This acts like thin grinding paste.

So although we use the very best quality oil available to minimise the effects of wear, it still degrades with increased usage, so regular oil changes are required.

The oil seals and O-rings are also of the highest quality but should be replaced with the oil along with the main piston shims, which also lose performance with fatigue and wear.

The oil and valve shims are the fundamental requirements for the creation of damping forces/ resistance and are constantly being cycled with every damper movement.

Often, the result of this wear is shown up as having to increase the dampers adjustments as the season progresses.

The importance of damper maintenance and servicing is critical and to get the best performance out of your damper receiving regular check ups is a must.

Listed below is exactly what the damper maintenance and servicing includes:-

Complete strip, thorough clean, and inspection for damage of the dampers main components.

Replacement of main piston valve shims and compression adjuster shims as necessary.

Replacement of all O-rings and oil seals with genuine factory items.

Fresh Fox JM92 Extreme Duty 400º F Oil.

Fresh Nitrogen gas charge.

Then they will be checked and damper will be reassembled using new components where necessary.

Should customers require any extra work done (new platforms, reservoirs, etc) this should be expressed when sending the shocks in for service.

A note about Shock Oil: The oil is the most important ingredient in a shock absorber. A shock absorber is a thermal device that converts kinetic energy into heat. The oil dictates how the shock feels and how it responds with the temperature increase.

We feel the oil is a vital component and only use genuine JM92 as this is the best oil Fox have found in 30 years of testing and evaluation.

Please clean shocks and remove springs prior to sending them to us. The will be a service charge if this is not done.
