Derived from the competition, the STXA range allows a height and hardness adjustment. Height adjustment on the front and rear (for vehicles permitting) by disc located on the threaded body of the shock absorber. Very precise hardness adjustment by a progressive wheel located in the head of damper rod. For all those who need to refine their setting to have a custom "setup". Galvanization treatment + corrosion coating to ensure greater longevity.

The threaded handsets ST Suspensions are supplied in sufficient quantity to equip the vehicle. They mount in place of the original suspension, without modification. If, for example, you only have springs in the back, it will also be the case with these ST Suspension kits.

The only models sold with cups are the STXTA threaded handsets. For any other model, please think of equipping you with original fits for editing. The kits ST Suspensions are delivered naked (damper cartridges and springs if applicable), unless an accessory essential to lowering is required. The force legs are in Galvanized Steel.
