Drive Hub Crankshaft SB Ford 3-Bolt 3.5in Long

The Drive Hub Crankshaft SB Ford 3-Bolt 3.5in Long is a precision-engineered rotating assembly component designed for small-block Ford engine builds and modifications. Built by Jones Racing Products—a trusted name in high-performance racing components—this crankshaft serves both street and competition applications where reliability and consistent performance are non-negotiable. Whether you're rebuilding a classic 289, 302, or 351W variant, this 3-bolt configuration provides the foundation for balanced power delivery and extended engine life.

This crankshaft features the 3-bolt main cap design, a proven architecture for small-block Ford applications that distributes loads evenly across the engine block while maintaining structural integrity under high RPM and boost conditions. The 3.5-inch throw dimension determines your engine's stroke, directly influencing displacement, torque characteristics, and rev-ceiling potential. At 0.96 lbs, the component's optimized weight-to-strength ratio reduces reciprocating mass, which improves acceleration response and reduces parasitic losses—critical factors in both street performance and drag racing scenarios. The compact footprint (4.9 x 3.7 x 6.45 inches) ensures straightforward fitment within standard small-block Ford bellhousing assemblies without requiring custom machining or adapter plates.

Mechanics and engine builders working on carbureted or fuel-injected small-block Ford platforms will appreciate the universal compatibility of the 3-bolt design across multiple block generations. Installation requires proper balancing to match your flywheel or flexplate, along with verification that your rod and piston combination align with the 3.5-inch stroke specification. This crankshaft is ideal for enthusiasts upgrading from stock cast units to forged aftermarket alternatives, or for those rebuilding tired engines with performance-oriented internals. Pair it with quality bearings, ARP fasteners, and precision balancing for maximum durability and predictable power output in street, strip, or track environments.
