Serpent introduces for the Spyder range of offroad cars / shocks, these special pre-oiled shock x-rings.
The special compounds silicone x-rings which are part of the shockseal package for the Spyder race-cars , are pre-soaked in high quality silicone oil for a minimum of 48 hours, which will ensure they have the right size when you assemble the shocks and no leaking will occur.
