FEULING HIGH LOAD premium performance BEEHIVE valve springs handle up to 750 lift camshafts. Designed for steep ramped large lift camshafts - These Feuling valve springs are made from premium stress relieved conical ovate wire with a nitrided surface heat treatment, shot-peened surface enhancements along with a Nano Peen polish. They have an extremely high level of fatigue life and are designed to handle the highest demands of performance engines with high lift, steep ramped camshafts. Dyno proven and track tested.
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 HIGH LOAD springs allow up to 750 lift cams, no rocker box clearancing required.
Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
Available for 5/16 and 7mm valves
FEULING BEEHIVE valve springs must be installed at the correct OPEN HEIGHT, matching max lift to the open height spec of the valve springs.
Kits include: FEULING HIGH LOAD BEEHIVE valve springs, lightweight 10 DegreeTitanium retainers manufactured from Ti-17 alloy and micropolished for enhanced fatigue life, machined heat treated chrome moly spring seats, seat shims and valve locks and a set of premium Viton valve seals equipped with a spring loaded valve stem wiper system.
Dont get stung by inferior valve springs!
