Shock Therapy Silent Cross Over Ring Replacement O-ring

Replacement O-rings for Silent Cross Over Rings

The O-rings we use are the same material NASA uses to seal compartments in satellites. Even though they are very tough, with time you may be able to wear one out or cut one by running through bushes. If this happens you can run your car without the O-rings on the cross over with no negative affects other than the clicking noise that can be heard without the O-ring. If you need extra or replacement O-rings you can purchase them here. They are not only specific to the shock diameter but also the manufacture of shock so be sure you are ordering the correct one for your car.
