Set of 4 o-rings, standard fit tolerance, for 16mm aluminum 1/8 scale RC shock pistons.
These o-rings are the standard size installed on all of our piston sets. You should replace your piston o-rings if they become worn or damaged.
The standard fit tolerance piston o-rings are sized so the o-ring barely makes contact with the wall of the 16mm shock body, but does not have too much friction drag. This lets very little shock oil blow by the piston.
4 o-rings include in package.
Designed to the highest tolerances for the serious racers.
