Description
The Dura-Bond CH-10 Camshaft Bearing Set is engineered for 1997–2003 GM LS-Series engines, including LS1, LS6, LQ4, LQ9, LM7, L59, and LR4 models. Constructed from seamless steel tubing with a thin layer of lead-based babbitt material, these bearings provide exceptional embeddability, conformability, and anti-seizure properties. The seamless design ensures easy installation without breakage or surface interruptions, while precision machining delivers industry-leading tolerances with wall variations as tight as 0.0004 inches. Ideal for performance rebuilds and OEM replacement applications.
