Precision Machining NEW Evo/TwinCam Valve Kit

Valve spring kit for Evo / Twin Cam

KIBBLEWHITE Precision Machining has taken advantage of the latest developments in valve spring wire chemistry and manufacturing techniques to develop ovate wire Beehive style springs for H-D applications.


The company has not only explored new manufacturing techniques in the development of the high performance valve springs, it also used simulation and FEA analysis software to overcome the torsional stresses unique to ovate wire springs, which in the past had limited the parameters within which they could be used.


The new Beehive valve springs, which are available for use in '84-'11 Evolution and Twin Cam engines, are progressively wound using heat treated and shot peened Kobe 'Super-Clean' chrome silicon based wire. To insure correct assembly height and resist keeper pull through, the accompanying Posi-Loc style retainers are designed with FEA software and made from hardened steel. Also included are hardened steel base washers to locate the spring and control lateral movement.
