Upgrade and Repair Kits
STX Upgrade Kit
Upgrade your ST model strut to a high-performance STX strut. Kit includes all items shown to add:
- High-flow oil return
- Tunable, velocity-sensitive compression damping
- Ability to set ride height anywhere within stroke of piston shaft; no more mid-stroke setting to achieve smooth ride
STX Lower Mount Rebound Assembly Upgrade
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.
Struts shipped prior to January 2013 will require machining modification to piston or new piston.
STX Seal Kit
All seals and O-rings needed to completely renew your STX strut. (Oil sold separately)
STX Rebuild Kit
Fork Fluid 5w
For all STX struts upper chamber and for STX struts lower chamber with 2016 and newer version rebound damping.
Fork Oil 10w
For bottom chamber of STX struts 2015 and older.
It is recommended to use Spectro Golden Cartridge Fluid 5w in both the top and bottom strut chambers for best seal compatibility. If using 5w fluid in the bottom chamber of a 2015 or older strut, recalibrate the rebound damping to a 0.005” clearance gap (see manual). It is also highly recommended to upgrade the rebound assembly to 2016 or newer for best performance
