High Load Beehive® Spring Kit

Machined from a premium grade Hi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processed thermal heat treat and super NexTex® finish to give these valve springs the needed fatigue life to exceed the high demands of V-Twin engines from stock to performance, FEULING® BEEHIVE® valve springs use a smaller lighter weight retainer which drastically reduces the valve weight creating a quicker revving and smoother motion than comparable dual or single valve springs., Valve springs are a direct bolt-in replacement, no spring seat or rocker cover machining required up to .565” lift, Springs will accommodate over .600 cam lift, but will require spring seat pocket machining on the cylinder heads to set correct spring open height, Smaller lighter weight retainers which drastically reduce the valve weight creating a quicker revving and smoother motion than comparable dual or single valve springs, Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics, Kits include: matched set of Feuling® High Load Beehive® valve springs, Ti retainers, machined spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with a spring loaded valve stem wiper system, ONLY recommended for large lift camshafts and RACE style engines as these valvesprings if not set properly will create extreme rocker arm deflection, Seat lbs./Installed Height, 151 Lbs. @ 1.475 (0.485 Lift), 144 Lbs. @ 1.498 (0.508 Lift), 143 Lbs. @ 1.501 (0.511 Lift), 140 Lbs. @ 1.511 (0.521 Lift), 124 Lbs. @ 1.562 (0.578 Lift), 120 Lbs. @ 1.582 (0.592 Lift), 304 Lbs @ 0.990 OPEN HEIGHT, Coil Bind @ .945, Recommended for .540”+ lift camshafts, Feuling® BeeHive® valve springs must be installed at the correct OPEN HEIGHT, matching max lift to the open height spec of the valve springs, Made in the U.S.A.
