Product Description
Dura-Bond CHP-25T High Performance Camshaft Bearing Set – 2004-2013 GM LS Engines
Dry-Film Coated, High Load-Capacity Cam Bearings for 2nd Design LS Blocks
The Dura-Bond CHP-25T camshaft bearing set is a high performance, higher load-capacity upgrade over the standard CH-25 bearing, engineered specifically for 2004–2013 LS engine blocks. Designed for engines running higher-than-stock valve spring pressures, aggressive camshaft profiles, or racing-style valvetrain setups, the CHP-25T delivers exceptional fatigue strength and long-term durability.
In addition to its reinforced construction, the CHP-25T features a secondary dry film lubricant coating for added protection during cold starts and potential oil starvation conditions. This added layer of defense makes it an ideal choice for performance street builds and high RPM race engines alike.
Key Features & Benefits
- High Load-Capacity Design: Performance upgrade over CH-25 bearings, engineered to handle increased spring pressures and aggressive camshaft profiles.
- Dry Film Lubricant Coating (“T” Series): Secondary coating provides added protection against oil starvation and startup wear.
- Fits 2nd Design LS Blocks: Designed for 2004+ blocks where bearing positions 1 and 5 housing bores measure 2.3460" to 2.3480".
- CH-23/CHP-23 Compatibility: Can be used in applications calling for CH-23, CHP-23, or CHP-23T bearings (certain 2004–2006 LS engines).
- Seamless Steel Construction: Eliminates bearing surface interruptions and reduces installation damage risk for improved reliability.
- Lead-Based Babbitt Layer: Superior embeddability, conformability, and anti-seizure properties 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.
- Enhanced Fatigue Strength: More than double the fatigue strength of conventional bearings while maintaining excellent Babbitt surface characteristics.
Fitment Requirements
Fits 2004–2013 GM LS engine blocks where cam bearing positions 1 and 5 housing bores measure 2.3460" to 2.3480".
Also compatible with applications that require CH-23, CHP-23, or CHP-23T cam bearings in certain 2004–2006 LS engines.
