VALVE SPRG 1.639 DUAL W/D

LUNATI/HOLLEY 73191-1 Features:

Lunati Valve Springs are manufactured using chrome silicon valve spring wire and cutting-edge heat treatment processes. This advanced heat-set takes the load loss out of the springs during the manufacturing process, opposed to during first use, to lengthen spring life and make the break-in process easier. These springs offer excellent fatigue life and load loss characteristics ideally suited for Saturday night oval track or drag racing.
