Dura-Bond CHP-25 Camshaft Bearing Set | Fits 2007-2013 4.8L 5.3L 5.7L 6.0L 6.2L GM LS Engines | for High-Performance Engine Builds

CHP‑25 High‑Load Fatigue Design – Engineered with enhanced fatigue strength for camshafts running aggressive spring pressures and performance profiles. Seamless Steel Core with Lead Babbitt – Single-piece shell prevents seizing and ensures uniform contact; babbitt lining reduces risk of scoring during start-up and torque loading. Drop-In Fit for 2007–2013 LS Blocks – Main and cam bearing housings sized for LS Gen III/IV blocks; measures 2.3460″–2.3480″ in positions 1 and 5. Replacement for CH‑23 Bearings – Fully backward-compatible—ideal for rebuilds where CH‑23 has been superseded in late LS blocks. Performance Embedability & Anti‑Seize – Babbitt material captures debris and conforms to journals, minimizing risk of cam damage in high-stress or contaminated oil conditions. Protect your LS camshaft with the Dura-Bond CHP‑25 high-performance cam bearing set—designed for GM small‑block engines from 2007–2013 (4.8, 5.3, 6.0, 6.2 L). These bimetal, seamless-steel bearings feature a lead-based babbitt lining known for superior embeddability, conformability, and anti-seize protection—ideal for performance builds or high-mileage engines. The CH‑25 spec also replaces the discontinued ‘CH‑23’ bearing for proper fit in later LS blocks. Engineered to resist fatigue from high spring loads, this set gives your camshaft the elite protection it deserves for reliable engine performance.
