KPMI SPRING KIT, BEEHIVE,.460" LIFT, TRIUMPH, 750, 1973-198

By taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, KPMI has developed a series of ovate wire Beehive style spring kits. By coupling these material 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, and manufacture a Beehive spring that will live and perform at a high level in Triumph High Performance applications. KPMI Ovate Wire Beehive Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened. The tapered shape of the spring allows for a retainer with a small OD. This reduces the reciprocating mass of the spring and retainer to less than that of a typical dual spring assembly. The retainer is a hardened steel, tightly toleranced, FEA design. The entire assembly is located by a properly fitting hardened steel basewasher that controls lateral movement adding to the performance and durability of the valve train.
