Valve Spring Kit - High Load Beehive® with TI Retainers - Twin Cam | XL | XR
Designed for high-performance engines, the FEULING PARTS Valve Spring Kit (Part 1205) features premium components engineered to handle aggressive camshaft profiles and high-lift applications. Crafted from stress-relieved conical ovate wire with nitrided surface heat treatment, shot-peened surface enhancements, and Nano Peen™ polish, these springs offer exceptional durability and fatigue life. The kit includes lightweight 10° Titanium retainers made from Ti-17 alloy, 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, ensuring reliable sealing and performance under demanding conditions. The use of a smaller, lighter retainer reduces valve weight, enabling quicker revs and smoother engine motion, ideal for high-lift, steep-ramped camshafts without requiring rocker box clearance. These valve springs are designed to accommodate up to 0.750 inch lift cams, with specific installed and open height specifications to optimize performance and longevity.
The springs have been dyno tested and track proven, providing confidence in their ability to withstand high stress and extended use in performance applications. The kit is a direct replacement for OEM components, requiring no machining or additional modifications for installation on compatible models. It is suitable for a variety of Harley-Davidson® engines, including '84-'04 Big Twin, '86-'03 XL, and '05-'17 Twin Cam models, with the capacity to handle larger camshafts when valve guide machining is performed. Proper installation of the springs at the correct open height is crucial to ensure maximum lift capacity and optimal engine operation. Made in the USA, this kit combines advanced materials and engineering to deliver improved engine responsiveness and durability in demanding riding conditions.
