1.282 Beehive Valve Spring Set

The 1.282 Beehive Valve Spring Set from COMP CAMS is a high-performance valve spring upgrade designed for engine builders and performance enthusiasts seeking improved valve control and reliability in modified or racing applications. This 16-piece spring set replaces factory springs that often cannot handle aggressive camshaft profiles, higher RPM limits, or forced-induction setups. Beehive-style springs compress more efficiently than traditional cylindrical designs, allowing tighter packaging and reducing valvetrain mass—critical factors when pushing an engine beyond stock parameters.

This set features an ovate (oval-shaped) cross-section geometry that delivers 386 pounds per inch of spring rate with a 1.181-inch coil bind dimension, ensuring adequate valve lift clearance without coil binding under full load. The dual-diameter design—1.077 inches inner diameter and 1.282 inches outer diameter—optimizes the contact surface and load distribution, reducing wear on valve stems and retainers during high-frequency cycling. COMP CAMS engineers these springs to maintain consistent pressure across the full valve lift range, preventing valve float and controlling spring surge even in extreme boost or nitrous applications. The beehive profile inherently generates less resonant frequency than conventional springs, translating to quieter, more stable valvetrain operation.

Mechanics and engine builders typically install this spring set when upgrading to performance camshafts rated above 0.500 inches of lift, or when converting to high-lift rocker arms in forced-induction platforms. The set of 16 springs covers both intake and exhaust valve positions on an eight-cylinder engine, or provides flexibility for four and six-cylinder applications with extras on hand. Proper installation requires precise valve seat pressures—measured when the valve is closed—to ensure optimal performance and longevity. Compatibility depends on your specific engine's bore diameter, rocker ratio, and pushrods; verify fitment against your camshaft manufacturer's recommendations before purchase for sale or review purposes.
