Product Description
Dura-Bond CHP-25 High Performance Camshaft Bearing Set – 2007-2013 GM LS Engines
High Load-Capacity Cam Bearings for 2nd Design LS Blocks
The Dura-Bond CHP-25 camshaft bearing set is a high performance, higher load-capacity upgrade over the standard CH-25 bearing, engineered specifically for 2007–2013 LS engine blocks. Designed for engines running increased valve spring pressures and more aggressive camshaft profiles, the CHP-25 offers improved durability while maintaining the excellent surface characteristics of traditional Babbitt bearings.
Built using Dura-Bond’s seamless steel construction and precision machining processes, these bearings deliver tight tolerances, superior conformability, and long-term reliability for both street performance and race applications.
Key Features & Benefits
- High Load-Capacity Upgrade: Performance version of the CH-25 bearing designed to withstand higher spring pressures and increased valvetrain loads.
- Fits 2nd Design LS Blocks: Designed for 2007 and up LS blocks where cam bearing positions 1 and 5 housing bores measure 2.3460" to 2.3480".
- CH-23 Compatibility: Can also be used in certain 2003–2006 LS engine applications that call for CH-23 cam bearings.
- Seamless Steel Construction: Eliminates bearing surface interruptions and reduces installation damage risk for improved reliability.
- Lead-Based Babbitt Layer: Provides superior embeddability, conformability, and anti-seizure protection compared to harder bearing materials.
- Precision Machined Tolerances: 100% machined surface with centerless ground OD and bored ID for wall variations under .0004" and consistent oil clearance control.
Fitment Requirements
Fits 2007 and newer GM LS engine blocks where cam bearing positions 1 and 5 housing bores measure 2.3460" to 2.3480".
May also be used in certain 2003–2006 LS engine applications requiring CH-23 cam bearings (verify block bore measurements prior to installation).
