## Description

Spring and retainer kits are key for maximizing reliability and performance on high output engines. Designed for demanding conditions, they ensure controlled valve closing at high RPM and reduce wear and failure risk within the valvetrain. With retainers in steel, aluminum or titanium and matched uprated springs, these kits improve engine efficiency and durability for intensive use.
