Drive hub SBC 1pc 2.510 x 1-1/8in

The Drive Hub SBC 1pc 2.510 x 1-1/8in from Jones Racing Products is a precision-engineered hub assembly built for high-performance marine engine applications requiring robust power transmission. Designed for small-block Chevy (SBC) configurations, this single-piece hub serves as the critical connection point between your engine's crankshaft and ancillary components—whether you're running a high-output fishing boat, performance watercraft, or specialty marine engine setup. This is the component that matters when reliability on the water is non-negotiable.

Built with the exacting tolerances Jones Racing Products is known for, this drive hub features a 2.510-inch diameter bore paired with a 1-1/8-inch shaft dimension, engineered to handle consistent torque loads and resist the vibration and thermal stress inherent to marine duty cycles. The one-piece construction eliminates joint failure points and delivers solid concentricity, which directly translates to smoother operation, reduced vibration transmission to the hull, and longer intervals between maintenance cycles. The compact footprint (4 x 1.95 x 5.7 inches) and lightweight design (0.39 lbs) make installation straightforward without compromising structural integrity—a balance only possible through professional-grade design and material selection.

This hub is ideal for boaters and marine engine builders working with SBC platforms who demand dependable performance in saltwater or freshwater environments. Whether you're upgrading an existing engine, rebuilding after hard miles on the water, or assembling a custom marine powerplant, proper hub selection directly impacts how your alternator, water pump, and other driven accessories perform. Verify compatibility with your specific crankshaft snout diameter and engine configuration before ordering; this hub's 2.510 x 1-1/8in dimensions suit standard SBC small-block applications but should always be cross-checked against your engine's existing setup.
