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 designed for Small Block Chevrolet engines that require high-RPM reliability and consistent power delivery. This single-piece hub assembly is ideal for both enthusiasts and professional engine builders who demand OEM-quality performance in naturally aspirated, supercharged, or turbocharged SBC applications.

The 2.410-inch outer diameter and 1-1/8-inch bore specification ensure the precise geometry necessary for tight tolerances and minimal runout, which is essential for maintaining high-RPM stability. The single-piece construction eliminates the risk of press-fit joint failures common in multi-piece designs, ensuring the hub maintains concentricity under extreme stress and thermal cycling. This design allows for superior load distribution across the crankshaft snout, reducing the risk of fatigue cracking during extended track sessions or forced-induction operation.

This hub is perfect for SBC engine swaps, pro-street builds, circle track racing, and any application where crankshaft reliability is paramount. It is compatible with OEM-style dampers and pulleys, making it a versatile choice for various performance applications. With its robust design, the Drive Hub SBC ensures that your engine maintains proper ignition timing and accessory drive synchronization for optimal performance.
