For LS enthusiasts who prefer a “Beehive” valve spring Lunati’s Ovate Beehive Valve Spring Kit (Pt. No. 74818K1) is available. These kits feature precision wound, 1.290” O.D., Ovate shaped, Beehive springs. Lunati Ovate Beehive springs are CAD designed with a unique ovate shape that places more of the material outboard of its center, concentrating more steel where it’s most needed. Each spring is precision wound to reduce stress and coil surge during operation, micro-peened, to reduce stress-risers, heat set, to increase longevity and reduce tension loss. Lunati Ovate Beehive valve springs should be assembled to yield 130 lbs., seat pressure (measured @ 1.800”) and 318 lbs., open-load pressure (measured @ 1.200”). They are engineered for today’s latest aggressive LS cam designs with valve lifts of up to .600”. Lunati Pt. No. 74818K1 Ovate Beehive Valve Spring Kits come with machined, heat treated 4140 Steel Valve Spring Retainers made from finest 4140 steel. Precision machined, 7-degree steel valve locks are also provided, for superior valve stem clamping force. The 74818K1 Beehive kit uses stock GM LS valve stem seals. These new Lunati kits provide maximum strength and durability for drag racing, circle track, off road, road course, marine or serious street performance applications.
