Drive Hub SBC 1pc 2.410 x 1-1/8in

The Drive Hub SBC 1pc 2.410 x 1-1/8in from Jones Racing Products is a precision-engineered crankshaft drive hub built for Small Block Chevrolet engines demanding high-RPM reliability and consistent power delivery. This single-piece hub assembly is purpose-built for enthusiasts and professional engine builders who require OEM-quality performance in naturally aspirated, supercharged, or turbocharged SBC applications. Whether you're restoring a classic muscle car, building a race engine, or upgrading a daily driver, a quality drive hub is critical to maintaining proper ignition timing, accessory drive synchronization, and overall engine longevity.

The 2.410-inch outer diameter combined with the 1-1/8-inch bore specification delivers the precise geometry required for tight tolerances and minimal runout, essential for high-RPM stability above 7,000 RPM where harmonic imbalance becomes critical. Jones Racing Products' single-piece construction eliminates press-fit joint failures common in multi-piece designs, ensuring the hub maintains concentricity under extreme stress and thermal cycling. The precisely machined surfaces accept OEM-style dampers and pulleys while providing superior load distribution across the crankshaft snout, reducing the risk of fatigue cracking during extended track sessions or forced-induction operation.

This hub is ideal for SBC engine swaps, pro-street builds, circle track racing, and any application where crankshaft reliability cannot be compromised. Installation is straightforward for experienced mechanics: the hub slides onto the crankshaft snout and seats against the snout shoulder, then is secured with the factory bolt. Verify your damper and pulley compatibility before ordering—this hub accepts standard Small Block Chevrolet accessories and is compatible with both factory and aftermarket dampers designed for the 2.410-inch hub diameter. Lightweight at just 0.39 lbs, it contributes minimal rotational mass while maintaining the structural integrity required for dependable engine performance in demanding conditions.
