Cam Bearing Set - GM LSX Block

The Cam Bearing Set - GM LSX Block from MAHLE ORIGINAL/CLEVITE is the foundation of a bulletproof camshaft support system for LS-series engines. Whether you're rebuilding a stock 5.3L, assembling a stroker package, or going full race with a radical cam profile, this standard journal bearing set ensures proper load distribution and oil flow to critical camshaft journals. Camshaft bearings wear constantly during engine operation—especially under high-lift, aggressive cam profiles—making a quality OEM replacement essential for engine longevity and reliability.

MAHLE ORIGINAL bearings are engineered with precision-machined bores and multilayer composite construction designed to handle the specific journal geometry of GM LSX blocks. The standard journal design maintains exact OEM clearances, ensuring proper oil wedge formation and hydrodynamic film strength under all engine speeds and loads. Each bearing in this complete set is manufactured to exacting tolerances and coated with a proprietary surface treatment that resists scuffing and premature wear—critical when running increased valve spring pressures or extended RPM ranges typical of modified LS engines.

This bearing set is mandatory for any complete LS engine rebuild, whether you're replacing worn bearings in a high-mileage core or installing fresh bearings during a bottom-end refresh on a new short block. The kit is fully compatible with all GM LS-series platforms including LSX, LS1, LS2, LS3, LS6, and truck variants. Installation requires standard engine machine shop practices and torque-to-yield specifications; proper clearance verification and oil-passage inspection before assembly ensures maximum bearing life and prevents catastrophic engine damage.
