FEULING ENDURANCE BEEHIVE valve springs allow up to 650 lift camshafts no spring seat machining required. 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.
Dont get stung by inferior valve springs!
Quicker Revving - Smoother Motion - Light Weight Ti Retainers
FEULING BEEHIVE valve spring kits are each hand measured and labeled specifically based on their coil bind / required open height. Our kits require you to measure installed height and may require use of included shims. This is so you can set up the springs specifically to your camshaft lift for quieter and smoother performance. Similar to tuning your suspension to your weight and riding style.
FEULING BEEHIVE valve springs use a much smaller and lighter weight retainer which drastically reduces the valve weight creating a much quicker revving and smoother motion than comparable dual valve springs.
FEULING Endurance springs allow up to 650 cam lift no machining or rocker box clearancing required.
Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
Available for 5/16 and 7mm valves
Kits include: FEULING ENDURACE BEEHIVE valve springs, lightweight 7 Degree Titanium heat treated 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.
