Feuling Parts 1101 - Feuling Parts Endurance Beehive Valve Spring Kit for Screamin Eagle Heads For

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.
