The Jones Racing Products Pulley Mounting Kit with Bolts & Bushings (Model WP-6104-MK) is a precision engine accessory designed for Small Block Chevy applications. This complete mounting solution delivers the hardware necessary for secure, reliable pulley installation in high-performance and street engine builds where belt drive integrity directly impacts overall engine reliability and longevity.
The kit includes all critical fastening components: grade-specification bolts engineered to withstand engine vibration and thermal cycling, plus precision bushings that reduce wear and vibration transmission to the block. Bushings are essential in pulley assemblies because they isolate the rotating load from direct metal-to-metal contact, preventing fretting corrosion and extending the service life of both the pulley and mounting surface. The compact package (3.6 x 1.1 x 4.15 inches, 0.15 lbs) contains everything needed for installation without requiring separate hardware sourcing—a practical consideration for engine builders and performance technicians managing multiple components.
This pulley mounting kit is intended for engine builders, restoration specialists, and performance enthusiasts working on Small Block Chevy platforms. Whether assembling a street engine, classic car restoration, or performance build, proper pulley mounting prevents belt slippage, accessory drive misalignment, and belt-off failures that compromise alternator output and water pump circulation. Jones Racing Products' reputation in the engine accessory market reflects their focus on fit and functional reliability rather than decorative appeal.
Small Block Chevy pulley mounting systems must accommodate standard bolt patterns established across decades of engine production. This kit maintains those specifications while providing the upgrade-grade bushings and bolts that address common wear points. The inclusion of both fasteners and isolation components in one kit reduces installation friction and ensures the mount functions as designed from the first startup.
