Valve Spring Kit - Steel Retainers - For 7.00 mm Valve Stem - Twin Cam

Upgrade your motorcycle's valve train with the FEULING PARTS Valve Spring Kit designed specifically for Twin Cam models. Constructed from heat-treated chromoly conical ovate wire, these springs are meticulously hand-measured and labeled to ensure precise open height and optimal performance. The kit features lightweight 7° steel retainers that significantly reduce valve weight, resulting in quicker revs and smoother valve motion. Dyno proven and track tested, this kit provides reliable performance under demanding conditions.

The kit includes Econo BeeHive® valve springs, machined heat-treated chromoly spring seats, seat shims, high-quality Viton® valve seals with spring-loaded stem wipers, and lightweight retainers made from steel or titanium options. These components work together to support valve lifts up to 0.585 inches, with seat pressure ranging from 163 to 183 pounds depending on open height. The design ensures compatibility with cams up to 0.574 inches lift for Harley-Davidson models from 1984 through 2004 and up to 0.585 inches lift for models from 2005 to 2017.

Installation is straightforward, as the Econo BeeHive® kit is a direct replacement requiring no machining or rocker box clearance adjustments. Proper installation of these springs at the specified open height and maximum lift is essential for optimal performance and longevity. Made in the USA, this valve spring kit is an excellent choice for riders seeking enhanced engine response, smoother operation, and increased durability in their Harley-Davidson Twin Cam engines.
