Dura-Bond camshaft bearing set for Chevy LS1 — CH-10 standard-journal kit, direct-fit OEM dimensions

The Dura-Bond CH-10 Camshaft Bearing Set is a direct-fit, standard-journal bearing kit engineered to replace the camshaft bearings in Chevy LS1 and other GM LS-series engines.

When rebuilding or refreshing an LS1 engine, correctly sized camshaft bearings are essential for smooth cam rotation and accurate oil clearance. The Dura-Bond CH-10 kit supplies the set of standard journal bearings specified for many GM LS-series builds, offered as a single packaged auto part that fits common OE dimensions. This kit helps restore factory tolerances after wear or during a camshaft upgrade, and it’s manufactured with consistent machining to suit rebuilders and performance shops.

How does this bearing set fit Chevy LS1 engines?

The CH-10 set is designed for GM LS-series blocks that use standard journal camshaft bearings. Each shell in the kit matches the OEM journal diameters so the camshaft rides within specified clearances without requiring additional machining for typical rebuilds. Fitment is straightforward for any engine assembled to factory specs.

• Direct-fit geometry for GM LS-series standard journals
• Supplied as a complete kit to cover all cam positions
• Intended for engines rebuilt to original tolerances
• Simple replacement process with common shop tools

What materials and construction can I expect?

Dura-Bond camshaft bearings are manufactured to provide consistent internal diameters and durable bearing surfaces. Though produced in China, the kit follows machining and material specifications appropriate for standard journal applications and normal engine oiling systems.

• Precision-turned bearing shells for accurate journal clearance
• Material formulation suited for cam and journal wear resistance
• Packaged as one quantity for convenience during rebuilds
• Compact packaging dimensions for safe shipping and storage

How do I install and inspect the CH-10 bearings during rebuild?

Installation involves cleaning the bores, aligning the bearing halves, and pressing or tapping them into the block using the appropriate driver. After assembly, check endplay and oil clearance with plastigage or micrometers to confirm the camshaft spins freely within spec before final assembly.

• Clean block bores and oil passages before installing
• Use a correct-size driver to seat bearing shells squarely
• Verify oil clearance and camshaft endplay with measurement tools
• Replace bearings whenever you fit a new or reground camshaft

Who is this for: The Dura-Bond CH-10 Camshaft Bearing Set is aimed at DIY mechanics, professional engine builders, and repair shops working on GM LS-series engines—especially Chevy LS1 owners restoring stock geometry or installing a like-for-like cam. It’s appropriate for routine rebuilds, engine refreshes, and projects that require standard journal replacement bearings supplied as a single, ready-to-install kit.
