OEM pistons are not designed for high horsepower applications, especially in forced induction engines. We've partnered with JE pistons to create what we think are the best line of Viper pistons available today. Capable of handling 1,700+ hp, these pistons are the keystone for the majority of our twin-turbo Viper or Paxton supercharged builds.
They feature high strength aluminum alloys, race critical manufacturing, double pin oilers, accumulator groove, valve reliefs, thick wall 93C wrist pins and wire locks. These pistons are desinged to deliver reliable performance in boost applications exceeding 20 psi. EED specs a matching ring package to fit your individual application.Availiable in standard and oversize bores.
Requires machine honing of the cylinder block.
