STX Lower Mount Rebound Assembly

Includes all parts and oil (1 bottle oil for each 2
kits purchased) 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.
Struts shipped prior to January 2013 will require
machining modification to piston or new piston.
