Description

Weight: 1.28
  • The centerpiece of both kits are the advanced COMP® Beehive™ Valve Springs, which deliver a host of well documented benefits over conventional valve springs
  • With the limited valve spring installed height of the Harley V-Twin engine, small spring pocket and today's higher lift cams, the VThunder engineers faced a challenge in designing an all-inclusive kit that would provide proper installation fo the Beehive™ Valve Springs
  • After extensive testing and research, the proper combination of parts has been identified and is now available
  • Both kits utilize the Beehive™ Valve Springs, but the 61378 kit allows for use of the stock 7mm valves and stock locks and the 61377 kit is designed for 5/16" valves and includes high performance 10° Super Locks™ for added strength
