• Made from premium stress-relieved conical ovate wire with nitrided surface heat treatment, shot-peened surface enhancements and Nano Peen™ polish.
• Uses a much smaller, lighter retainer to reduce valve weight and improve response.
• Dyno proven and track tested for extreme fatigue life and reliability.

Key specifications:

• Seat loads: 170 lb at 1.935" (0.720" lift), 185 lb at 1.900" (0.685" lift), 200 lb at 1.845" (0.630" lift), 208 lb at 1.819" (0.604" lift), 215 lb at 1.800" (0.585" lift), 217 lb at 1.789" (0.574" lift).

Installation notes: valve springs must be installed at the correct open height, matching the cam max lift to the spring open height spec. Feuling® BeeHive® kits are direct replacements with no rocker box clearing required for many applications; larger camshafts may require valve guide machining for seal-to-retainer clearance.
