CP-Carrillo SC7027-4 Forged Piston & Ring Set Honda D-Series 75mm 9.0:1

Designed for builders seeking a reliable upgrade over OEM components, this kit delivers a 75.0mm standard bore and a 9.0:1 compression ratio, making it well-suited for naturally aspirated, turbocharged, supercharged, and nitrous oxide applications.

Each piston is CNC-machined from high-strength 2618 forged aluminum and features a dish-style crown with four valve reliefs. The deep valve relief design accommodates high-lift camshafts and is compatible with +1mm oversized valves. With a compression height of 1.181 inches and a lightweight construction of approximately 240 grams per piston, these pistons reduce reciprocating mass for improved throttle response and high-RPM performance.
