This is a shock rebuild seal kit from Schmidty Racing Suspensions for CST 2.0" coilover or smooth body shocks with non reservoir or reservoirs. These are for 2.0" shock bodies with 5/8" shafts. These are for Offroad series shocks. These kits will not have the clicker o-rings for UTV shocks, and will not have the o-rings for the bodies/reservoir to the piggyback cap; that are in those kits as well.
