“Power means nothing until the rest of the car can use it.”

Generic nitrile seals degrade faster under sustained heat and react poorly with full-synthetic lubricants, leading to oil consumption that creeps up quietly until the damage is done. The Viton compound in these COMP Cams seals maintains its sealing integrity at higher temperatures and resists chemical breakdown, making them the sensible choice for any built engine or car that sees regular track use.
