Part Description
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 0.565" lift.
- Springs will accommodate over 0.600 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.
- Kit includes: 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.
- Seat lb/Installed Height.
- 151 lb @ 1.475" (0.485" Lift).

- 143 lb @ 1.501" (0.511" Lift).
- 140 lb @ 1.511" (0.521" Lift).
- 124 lb @ 1.562" (0.578" Lift).
- 120 lb @ 1.582" (0.592" Lift).
- 304 lb @ 0.990" open height.
- Coil Bind @ 0.945".
- Recommended for +0.540" 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 USA.
- Only recommended for large lift camshafts and race style engines as these valvesprings if not set properly will create extreme rocker arm deflection..
