* All KPMI® retainers are designed using the latest CAD software available. Further, the retainers are tested using 昀椀nite element analysis (FEA) to ensure the
retainer can endure high stress levels during operation. By using billet aircraft alloy material, heat treating it, and then employing our high powered design software,
KPMI® is able to maximize weight saving by incorporating a series of drilled holes in the retainers. These retainers are both strong and light, allowing signi昀椀cant
reduction to overall valvetrain mass, which is known to improve performance.
