Each piston is forged from 2618-T6 aluminum to ensure maximum strength, durability and performance under extreme applications. Each piston has been developed, tested and raced by championship winning professionals, enabling CP Pistons to offer the best available part on the market while exceeding your expectations. Full-radius crown designs maximize quench while eliminating hot spots. CPK Kits come with a piston, proprietary treated wrist pin, circlips, rings and Cometic top end gasket kit. Proprietary treated wrist pins eliminate pin galling while reducing friction and increasing durability. CPKX Kits feature CP's latest Project X technology, which incorporates a fully boxed style piston which ensures a high-strength, lightweight assembly. CPKX Kits also includes a DLC pin ($60.00 value); this technology has been proven and used in the highest forms of motorsports because of its high resistance to abrasive wear, which extends the service life and reliability under extreme conditions. CPKX Kits include a Project X piston (coated), DLC pin, circlips, rings and Cometic top end gasket kit.
