Shock Custom Valving and Rebuilding Services

For Porsche 911, 912, 930

Shock Modification and Testing For Porsche 911/912/930

For Bilstein Shocks and Strut Inserts Only

Shock Reconditioning

For the rear, we’ll media blast the shock body, put a fresh coat of paint and replace decals to make the shocks look new.

Custom Valving and Rebuilding

Custom valve your Bilstein Shocks or inserts to match your spring rate. Choose the torision bar size or spring rate in the configuration table below.

Specific custom valving is also available. Call us at +1 408.297.2789

Service is performed by opening the shock, replacing the shim stack and sealed. Shock is then filled with fresh oil, properly sealed and charged. Each shock is dyno tested to ensure proper valving and pair consistency. Dyno charts will be included with this service.

Bump Stops

Add a new bump stop the shock.

Shock Body Shortening

Shortening shock body increases travel range. Much needed on lowered cars. Shock body is shortened by 19mm.

This is an add-on service to custom valving/rebuilding service as the shock needs to be opened for the modification.

Snap Ring Groove Machining

In order to install a coilover sleeve conversion kit, grooves need to be machined into the shock body in order to hold a snap ring in place.

Dynamometer Testing

Have your shocks tested on our dynamometer to establish a baseline before any work is perforemed. Dyno testing lets us diagnose health and function of the shock.

Bushing Replacement

Bushings on old shocks often deform. We recommend replacing these bushings alongside with shock rebuilding. Service includes new lower and upper bushings.
