Cam Bearing Set - GM LS 08-10

The DURA-BOND Cam Bearing Set for GM LS 08-10 engines (MPN CH-25) is a precision camshaft bearing kit designed for standard journal applications in LS-series engine builds. This set provides OEM-specification bearing surfaces engineered to maintain critical oil clearances and camshaft alignment throughout engine operation, whether in stock rebuild scenarios or performance modifications.

Camshaft bearings are load-critical components that support rotating shaft geometry under continuous lubrication. DURA-BOND cam bearing sets are manufactured to hold tight tolerances on bore diameter and journal seating, ensuring proper oil film formation between bearing surface and shaft. The standard journal configuration in this kit matches OEM specifications for LS engines from 2008–2010 model years, making it suitable for complete engine rebuilds, long-block assembly, or bearing replacement during performance work. Proper bearing sizing is essential—undersized or oversized bearings create inadequate oil clearance, leading to bearing wear, metal transfer, and eventual seizure.

This bearing set is specified for LS engine builders, machine shops performing complete rebuilds, performance enthusiasts undertaking cam upgrades, and rebuilders restoring stock long-blocks. The GM LS platform spans multiple displacements (5.3L to 7.0L) and years; verifying exact engine code and year ensures correct bearing fit. Bearing selection is non-negotiable in engine assembly—choosing the correct part number prevents costly reassembly and protects against internal damage during operation.
