Hex Shaft

The Hex Shaft from K.S.E. Racing is a precision power steering pump drive shaft engineered for high-performance racing and street applications requiring reliable belt-to-pump power transfer. Designed for builders and technicians who demand consistent steering response under extreme conditions, this component serves as the critical mechanical link between engine rotation and steering system pressurization. Whether you're upgrading a race car or maintaining a performance vehicle, the Hex Shaft ensures smooth power delivery to your steering pump without slippage or premature wear.

Manufactured from durable steel in natural finish, the Hex Shaft features a 3/8-inch hex drive interface that meshes directly with compatible K.S.E. power steering pump designs. The hex geometry provides superior torque transmission and prevents rotational slipping compared to conventional round shafts, critical when dealing with high pump pressures or aggressive serpentine belt tension. At just 0.28 lbs and measuring 2.8 x 0.9 x 5.5 inches, this compact drive shaft integrates seamlessly into engine compartments with space constraints while maintaining the structural integrity required for sustained performance duty.

This shaft is essential for anyone rebuilding or upgrading a K.S.E. Racing power steering system, particularly in drag racing, circle track, or street rod applications where steering precision matters. Installation requires confirmation of pump hex pocket compatibility and proper belt tension verification post-installation. The natural steel finish resists corrosion in typical engine environments, though builders in salt-exposed regions may consider protective coating for extended longevity.
