P/S Pump Alum with 3/8 Hex Drive Toyota

The P/S Pump Alum with 3/8 Hex Drive Toyota from SWEET is a compact, purpose-built power steering pump designed for Toyota enthusiasts and professional fabricators undertaking custom hydraulic system builds. Whether you're assembling a street rod, restoring a classic, or engineering a bespoke engine conversion, this aluminum pump delivers reliable flow in a lightweight package that minimizes underhood real estate and curb weight. Its 3/8-inch hex drive shaft interface ensures straightforward coupling to serpentine belt systems, making it an ideal choice for engine bay layouts where space and weight savings matter.

Constructed from lightweight aluminum, this pump reduces parasitic load on the engine compared to cast-iron alternatives while maintaining the structural integrity required for consistent pressure delivery. The 3/8-inch hex drive shaft is a standard interface found across aftermarket power steering solutions, allowing seamless integration with common belt-driven configurations and custom bracket arrangements. At 3.95 pounds and measuring 7.7 x 7.7 x 8.7 inches, the compact footprint makes it an excellent fit for tight engine compartments typical of vintage Toyota platforms and modified builds where traditional pump geometries prove unwieldy. Aluminum construction also resists corrosion better than bare steel, extending service life in both street and race environments.

Mechanics and fabricators building custom Toyota platforms—from 4K-series truck swaps to FJ40 restorations—will appreciate the direct application fit and simplified plumbing layout this pump enables. The 3/8-inch hex drive couples cleanly to aftermarket pulley sets and custom belt runs, eliminating the need for expensive adapter brackets or re-engineering existing mounts. Installation requires basic mechanical aptitude and standard hand tools; ensure your reservoir, hose routing, and pressure relief valve are rated for your specific application's flow demands. This pump is compatible with Toyota hydraulic systems requiring compact, aluminum-bodied solutions and pairs well with custom power steering lines and remote-mounted reservoirs in modified vehicle platforms.
