KIBBLEWHITE Beehive Spring Kit - 0.660" Lift - Twin Cam | XL | XR1200

By taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, KPMI has developed ovate wire Beehive style springs that will live and Perform at a high level in Harley Davidson applications. By coupling hese developments with strict KPMI design protocols and employing multiple design, simulation, and FEA analysis software, we were we able to overcome the torsional stresses unique to ovate wire springs that previously severely limited their operating prameters. This was critical, as there are nearly 100 camshaft part numbers available, these applications. KPMI Beehive Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened. The hardened seel basewashers included in these kits are designed to locate the spring and control lateral movement. KPMI made OEM replacement seals are included for a more complete performance valvetrain solution.
