Product Description
Dura-Bond CH-25 Camshaft Bearing Set – 2004-2013 GM LS Engines
Seamless Bimetal Cam Bearings – Direct Replacement for CH-23 Applications
The Dura-Bond CH-25 camshaft bearing set is engineered specifically for 2004–2013 GM LS-based engines and can also be used in applications that originally required the discontinued CH-23 bearings (2004–2006 LS engines). Designed with seamless steel construction and precision-machined tolerances, this set provides dependable oil control, durability, and long-term reliability for both stock rebuilds and performance applications.
Built from a seamless steel tube with a thin layer of lead-based babbitt material, CH-25 bearings offer superior embeddability, conformability, and anti-seizure characteristics. This design reduces the risk of engine failure compared to harder bearing materials and ensures consistent camshaft support under high load and RPM conditions.
Key Features & Benefits
- Seamless Steel Construction: Eliminates breakage and bearing surface interruptions during installation while providing uniform strength and durability.
- Lead-Based Babbitt Layer: Offers excellent embeddability, conformability, and anti-seizure protection for reliable camshaft support in street and performance builds.
- Precision Machined Design: 100% machined surface with centerless ground OD and bored ID delivers wall variations as tight as .0004", ensuring consistent oil clearance.
- Replaces Discontinued CH-23: Suitable for 2004–2006 LS engines that originally required CH-23 bearings.
- Correct for 2nd Design Blocks: For 2004+ engines with 2nd design position 1 and 5 housing bore size of 2.3460"/2.3480".
