Feuling Beehive Valve Spring Kit w Titanium Retainers

Feuling Hi Load Beehive Spring Kit valve springs are a direct bolt in replacement, no spring seat or rocker cover machining required up to 0.565 lift. These springs will accommodate over 0.600 cam lift but will require spring seat pocket machining on the cylinder heads to set correct spring open height. Milwaukee Eight HIGH LOAD springs are machined from a premium grade Hi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processed thermal heat treat and super NexTex finish to give these valve springs the needed fatigue life to exceed the high demands of V-Twin engines from stock to performance.
