Experience enhanced performance with our Endurance Beehive® Valve Springs, meticulously crafted from premium-grade hi-tensile chrome silicon single-conical ovate wire. These springs are shot-peened and treated with a special thermal heat process and super NexTex® finish, ensuring exceptional fatigue life that meets the rigorous demands of V-Twin engines.
Designed with a smaller and lighter weight retainer, our springs reduce valve weight, allowing for quicker revs and smoother motion. This kit is a direct bolt-in replacement for up to 650" cam lift, eliminating the need for machining or rocker box clearancing.
The complete kit includes: Endurance Beehive® valve springs, lightweight 7° super Titanium heat-treated retainers, machined spring seats, seat shims, valve locks, and a set of premium Viton® valve seals, all equipped with a spring-loaded valve stem wiper system.
Specifications for seat lbs./installed height are as follows: 198 lbs. at 1.685" (.535" lift), 194 lbs. at 1.703" (.553" lift), 190 lbs. at 1.724" (.574" lift), 187 lbs. at 1.754" (.604" lift), 185 lbs. at 1.780" (.630" lift), 160 lbs. at 1.800" (.650" lift), and 375 lbs. at 1.150" (open height) with coil bind at 1.100".
It is crucial that Feuling® BeeHive® valve springs are installed at the correct OPEN HEIGHT, matching the maximum lift to the specified open height of the valve springs. Proudly made in the U.S.A.
Note: Feuling® BeeHive® valve spring kits are direct replacements with no machining or rocker box clearance required up to .574" lift for 84-04 Big Twin and 86-03 XL, and up to .650" lift for 05-17 Twin Cam. Larger camshafts may require valve guide machining for seal to retainer clearance.
