Dura-Bond CH-10 Camshaft Bearing Set – 1st Gen LS Engine Block (1997–2003)
Fits LS1, LS6, LQ4, LQ9, LM7, L59, LR4 Engines
The Dura-Bond CH-10 Camshaft Bearing Set is designed for 1st generation LS engine blocks (1997–2003) and delivers unmatched precision, durability, and performance. Constructed from seamless steel tubing with a thin layer of lead-based babbitt material, these bearings provide superior embeddability, conformability, and anti-seizure protection—reducing engine wear and preventing failures that can occur with harder bearing materials. The seamless construction allows for easier installation, while the centerless ground outer diameter and bored inner diameter result in wall variations of just .0004", offering exceptional tolerance and system design flexibility.

For later 2003–2007 engines with the 2nd design (Positions 1 and 5 housing bores 2.3460"/2.3480"), see Dura-Bond part CH-25.
