Valve Spring Kit - TI Retainers - For 5/16" Valve Stem - EVO | Twin Cam

Upgrade your engine's performance with the FEULING PARTS Valve Spring Kit designed specifically for 5/16" valve stems in EVO and Twin Cam models. Crafted from heat-treated chromoly conical ovate wire, these springs are hand-measured and labeled to ensure precise open heights, optimizing valve operation. The kit features lightweight 7° steel or titanium retainers that significantly reduce valve weight, enabling quicker revs and smoother engine motion. These components are dyno proven and track tested to meet high-performance standards for demanding applications.

Included in this comprehensive kit are Econo BeeHive® valve springs, machined heat-treated chromoly spring seats, seat shims, valve locks, and a set of premium Viton® valve seals with a spring-loaded valve stem wiper system. The springs support up to 0.585" lift with an impressive seat load of 183 lb at 1.760" installed height, ensuring durability and reliable operation across a range of valve lifts. The design allows installation without machining or rocker box clearance modifications for cams up to 0.574" lift in '84-'04 Big Twin and '86-'03 XL models, and up to 0.585" lift in '05-'17 Twin Cam models.

Manufactured in the USA, these valve springs require correct open height matching to maximum lift for optimal performance and longevity. Whether upgrading for increased horsepower or smoother throttle response, the FEULING PARTS Valve Spring Kit offers a reliable and efficient solution for high-performance motorcycle engines.
