Please note: The effective price increase a result of sweeping increases in GM pricing and has nothing to do with us.

The W Bodies have an inherent issue with bouncing after lowering springs have been installed. This problem is not the fault of the springs or the struts, but rather the result of an incorrect strut rod retainer.

The stock retainer is too deep to be used with lowering springs and does not securely hold the end of the strut rod against the strut mount. For this reason, there is a point where the vehicle is riding on just the springs and getting no dampening effect from the struts. These shallower washers allow the spring to, once again, constantly be held in compression.

These will almost always eliminate pogo altogether but at worst will greatly reduce the affect and the knocking associated with it.
