Pump Shaft For All KSE 3/8 Hex Direct Drive

The Pump Shaft For All KSE 3/8 Hex Direct Drive is a precision replacement component engineered for K.S.E. Racing power steering pump systems. This shaft serves as the critical connection point between your engine's drive mechanism and the pump's internal gearing, enabling consistent hydraulic pressure delivery to your steering system. Whether you're rebuilding a racing power steering pump or replacing a worn OEM shaft, this direct-drive component ensures reliable performance in high-demand steering applications.

Constructed from durable steel in natural finish, the pump shaft features a 3/8-inch hex drive interface that ensures secure coupling with compatible pump housings and drive belts. The 3/8 hex configuration is the industry standard for KSE Racing pumps, providing positive engagement that resists slip under load while maintaining alignment during operation. With compact overall dimensions and a lightweight profile of 0.49 lbs, this shaft balances structural integrity with minimal rotational mass, reducing parasitic drag on your engine while sustaining the torque demands of pressurized hydraulic systems.

This component is ideal for racing enthusiasts, fabricators, and service technicians who maintain or rebuild KSE power steering pump assemblies. Compatibility spans all KSE 3/8 hex direct-drive pump models, making it a versatile replacement for high-performance street, track, and competition vehicles. Installation requires mounting into the pump housing body and connecting to your serpentine belt or direct-drive system—a straightforward process for experienced builders. Keep a spare shaft on hand for competition events or routine maintenance to minimize downtime and ensure steering responsiveness when it matters most.
