Description
If you’re running a ’99-’06 Harley-Davidson Twin Cam with a mechanical spring tensioner, you’re operating with outdated cam chain technology that limits reliability and performance. This Feuling conversion kit upgrades your engine to the superior late-model hydraulic tensioner system—eliminating spring wear, reducing noise, and delivering consistent valve timing under sustained high RPM operation. It’s a comprehensive solution that transforms your powertrain without requiring a complete engine rebuild.
The kit includes everything needed for the conversion: a Race Series billet oil pump with high-flow camplate, full-travel lifters, hydraulic tensioner housings, cam chains, sprockets, and all fasteners and gaskets. All components are engineered to work together as a system, and the inclusion of a rocker box gasket kit means you can reuse your factory one-piece pushrods, keeping costs down while maximizing reliability.
