Valve Spring Kit - Endurance Beehive with TI Retainers - TC with SE Heads

Highlights

• 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 are a direct bolt-in replacement (Up to 650 cam lift and doesn't require machining or rocker box clearancing).
• Eliminates valve spring separation, maximizes stability, reduces valve-train noise and harmonics.
• FEULING BEEHIVE valve springs must be installed at the correct open height, matching max lift to the open height spec of the valve springs.
• Machined from a premium grade Hi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processed thermal heat treatment and super finish.
• Kit includes FEULING ENDURACE BEEHIVE valve springs, lightweight 7 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.
