About this product
The Feuling HP+ Chain Drive Conversion Kit converts a '99-'06 Twin Cam to hydraulic chain tensioners using the HP+ oiling package rather than Race Series.
This is the same conversion as the Race Series kit and a different tier of hardware. HP+ uses a high volume oil pump and high flow billet cam plate, which delivers the temperature and pressure gains without the billet 7075 Race Series pump. For a street Twin Cam that needs the tensioner problem solved and a healthy oiling system, it is the sensible spend.
What the HP+ Conversion Kit Includes
Conversion camshafts update the early mechanical style tensioner system to the late style hydraulic chain drive. Around them sit a Feuling HP+ high volume oil pump, a high flow billet cam plate, REAPER series camshafts, HP+ hydraulic roller lifters and Timken bearings. Fast Install adjustable pushrods can be fitted without removing the top rocker covers, which saves hours on installation and on any future adjustment.
