Dura-Bond Bearing

Dura-Bond Camshaft Bearings & Engine Bearing Sets for Performance Rebuilds

Dura-Bond Bearing has been manufacturing engine bearings for domestic V8 engines since 1947 — and their camshaft bearings, cam plug kits, and engine bearing sets are the choice of professional engine builders who understand that bearing quality directly determines engine longevity and oil pressure consistency. For performance rebuilds and restorations where the bottom end has to be right, Dura-Bond is the correct specification.

Camshaft Bearings

Dura-Bond's camshaft bearings are their flagship product and the reason the brand has the reputation it does in the engine building community. Camshaft bearings are a critical and often overlooked component in any engine rebuild — they support the camshaft through the full range of engine operating conditions and must maintain correct oil clearance to ensure proper cam lubrication and consistent valve timing.

Dura-Bond cam bearings are manufactured from high-quality bimetal and trimetal materials with precise bore dimensions and correct wall thickness for each application. Their bearings are available in standard and undersized dimensions to accommodate camshaft journals that have been reground during the rebuild process. Correct bearing selection — material, size, and oil hole alignment — is critical for proper cam lubrication and engine longevity.

Cam Plug Kits

Dura-Bond's cam plug kits provide the expansion plugs needed to seal the camshaft gallery at the rear of the block — a component that's replaced as a matter of course during any thorough engine rebuild. Their kits include the correct plug size and material for each application, ensuring a leak-free seal that holds under the oil pressure demands of a performance engine.

Engine Bearing Sets

Dura-Bond's engine bearing sets cover main and rod bearing applications for domestic V8 engines, providing the complete bearing complement needed for a full bottom-end rebuild in a single, matched set. Their bearings are manufactured to correct dimensional specifications with appropriate crush and spread for proper installation and oil clearance in each application.

For performance rebuilds running increased oil pressure or modified oiling systems, Dura-Bond's bearing material selection provides the load capacity and wear resistance needed to survive the demands of a high-output engine. Correct bearing clearance — achieved through proper bearing selection and precision machining — is the foundation of consistent oil pressure and long engine life.

Applications

Dura-Bond bearings cover the most popular domestic V8 engine families — small block and big block Chevy, LS-series, small block and big block Ford, FE-series, and Mopar small block and big block applications. Their comprehensive application coverage makes them the go-to source for engine builders working across multiple domestic platforms.
