Camshaft Break-In Lube

The Camshaft Break-In Lube by HOWARDS RACING COMPONENTS is a specialized assembly lubricant formulated to protect freshly machined camshaft and lifter surfaces during engine break-in. This product is essential for anyone rebuilding or servicing high-performance engines, whether for racing, law enforcement pursuit vehicles, or tactical operations where engine reliability is non-negotiable. The 4 oz bottle delivers concentrated lubrication where it matters most—at the point of initial contact between cam lobes and lifters, where conventional oil alone cannot provide adequate boundary protection.

This conventional-formula break-in lube contains a proprietary blend of extreme pressure additives and zinc-based anti-wear compounds (ZPM chemistry) designed to prevent scuffing, spalling, and premature wear during the critical first operating hours. Unlike standard motor oil, this assembly lubricant clings to vertical cam surfaces and provides a sacrificial film that absorbs shock loads when lifters first contact aggressive cam profiles. The formulation is compatible with both flat-tappet and roller camshaft systems, allowing mechanics to apply it directly to cam lobes, lifter faces, and valve train components prior to engine startup without risk of viscosity breakdown or additive separation.

Professionals in engine rebuild shops, performance tuning facilities, and military vehicle maintenance teams rely on Camshaft Break-In Lube during initial assembly of any engine featuring a new or remanufactured camshaft. The compact 4 oz bottle is ideal for single-engine jobs and fits easily in any mechanic's toolkit. Apply generously to all cam lobes and lifter faces before installing the cylinder head, then allow the engine to idle gently during the first 500–1000 miles of operation while continuing with conventional break-in procedures. This product is not a substitute for proper break-in oil changes; rather, it complements standard lubrication protocols by providing localized protection where wear is most severe.
