OE+ Hydraulic Chain Conversion Camchest Kit / Early Twin Cam

The Feuling OE+ Hydraulic Chain Conversion Camchest Kit updates a '99-'06 Twin Cam to hydraulic tensioners using the OE+ tier of Feuling hardware.

Feuling offers this conversion at three levels, and OE+ is the entry point. It solves the same problem the Race Series and HP+ kits solve, replacing the early mechanical cam chain tensioner system with the later hydraulic one, at the lowest cost of the three. For a street Twin Cam where the goal is reliability rather than a horsepower target, that is often the right call.

What the OE+ Kit Includes

Conversion camshafts are the heart of it, using '99-'06 inner cam journals with '07-'16 outer journals so the later chain drive components fit an early motor. Sprockets, hydraulic tensioners, chains and spacers all ship with the kit. Around them sit a Feuling High Volume oil pump, a High Flow camplate, Reaper series camshafts, hydraulic roller lifters, adjustable pushrods and Timken bearings. Feuling designed the cam profiles to widen the torque band and improve fuel economy rather than chase peak numbers.
