The Michigan Motorsports 3-Bolt LS Cam Sprocket is a direct-replacement timing gear designed for early GM LS engines utilizing a 24X (1X) cam signal and three-bolt camshaft configuration. Commonly required during timing chain service, camshaft upgrades, or engine rebuilds, this sprocket restores correct camshaft indexing and cam/crank signal synchronization. Built to OEM-style specifications, it replaces GM part numbers 12552953 and 12576407 and delivers reliable performance for stock rebuilds and mild performance applications.
