The H-Grind Camshaft is an OEM-spec hydraulic replacement that reproduces the original H-grind profile used in 1948–1984 Big Twins. Ideal for repair and restoration of 74" and 80" engines, it preserves the factory timing characteristics with unique front and rear timing specifications. 🔧⚙️
It is available for generator engines with either inner cam bushings or inner cam bearings, and for early and late alternator applications with differing cam gear pitch diameters. Designed for direct fitment in restoration projects where authenticity and correct timing are required.
