Description

The CP Pistons SC7427 is a set of forged aluminum pistons designed for high-performance racing engines. They feature anti-detonation grooves to protect the top ring and a V-shaped accumulator groove to manage blow-by and enhance ring seal. The pistons are fully CNC machined and balanced to +/- 1 gram, with a 100mm bore size and a 9.0:1 compression ratio.

These pistons include piston rings, wrist pins, and circlips. They are constructed from high-strength aluminum forgings and are designed with super lightweight characteristics. Additional features include pin lock grooves for easier lock removal and double pin oilers for improved wrist pin lubrication.
