• All KPMI® retainers are tested using finite element analysis (FEA) to ensure theretainer can endure high stress levels during operation.
• Constructed of heat treated billet aircraft alloy material with drilling a series of holes in the retainers maximizes the weight savings.
• These retainers are both strong and light to improve reduction to overall valvetrain mass, which is known to improve performance.
• Retainer offset 0.070” for taller installed height. Basewashers counter-bored to accept a 0.720” OD seal. Basewasher fits over 0.625” guide top.
