Eliminate spring powered chain adjusters
Engines converted to 2007 type cams and chain drives will have higher output due to less power loss from older spring powered chain tensioners. Instead of the original spring adjusters, new roller cam chains use engine oil pressure to maintain proper chain tension
Camshafts on all 99-06 Twin Cam 88 engines (exc. 2006 Dyna) can be updated to new style roller chain drives
Designed for use with stock H/D hydraulic lifters
Installing 2007 roller cam chains on earlier engines requires series N Andrews camshafts Stock H-D parts are required: 2007 cam support plate, 2007 or later oil pump, cam sprockets and chains and both hydraulic chain adjusters
Matching EZ-install pushrods kits are sold separately. EZ-install pushrods do not require removal of gas tanks or rocker boxes when installing bolt-in camshafts
