HP Cam Bearing Set - BBM

The HP Cam Bearing Set - BBM (Model PDP-17) from DURA-BOND is a precision-engineered camshaft bearing kit engineered for high-performance Mopar B-Series and RB-Series engines, including the legendary 426 Hemi platform. This bearing set is an essential component for engine builders and mechanics seeking to maintain peak valve-train geometry and engine reliability under demanding conditions. Whether you're restoring a classic muscle car, building a competition engine, or maintaining fleet vehicles, proper camshaft bearing selection directly impacts engine longevity and performance consistency.

DURA-BOND's HP Cam Bearing Set utilizes standard journal sizing optimized for compatibility with OEM and aftermarket camshaft profiles across Mopar B and RB platforms. The bearing kit is manufactured to precise tolerances to ensure proper oil clearance, reduce friction losses, and distribute thermal load evenly across the journal surface. Compact at 2.75 x 2.6 x 5.25 inches and weighing just 0.48 lbs, this bearing set maintains the weight characteristics critical for high-rpm applications while delivering the durability required for sustained performance. The standardized journal design ensures drop-in compatibility with existing engine blocks without requiring machine work.

Engine builders, machine shops, and enthusiasts restoring Mopar B/RB-Series engines—including 426 Hemi variants—depend on reliable bearing sets to maintain OEM specifications and performance targets. Installation is straightforward during engine assembly or rebuild: position the bearing set into the cylinder block's journal bores, verify proper seating, and verify oil supply ports are unobstructed. This bearing set is ideal for stock rebuilds, mild performance builds, and high-rpm competition engines where precision bearing clearance is non-negotiable. Always consult engine assembly specifications and use proper installation procedures to achieve optimal bearing life and engine performance.
