STX Lower Mount Rebound Assembly

STX Lower Mount Rebound Assembly

Includes all parts to completely replace any STX lower mount rebound damping assembly. This upgrade provides much stronger, positive rebound response to tackle the wheel bounce and chassis bounce experienced with heavy axles and heavy sprung weight.

All STX struts shipped beginning January 2016 come with this upgrade.

Note : Struts shipped prior to January 2013 will require machining modification to piston or new piston.
