PSC Jeep Wrangler JK 3.8L Power Steering Pump Kit 2007-2011
PK38JP1
The PSC Jeep Wrangler JK 3.8L Power Steering Pump Kit 2007-2011 upgrades the hydraulic supply on 2007–2011 Wrangler JK 3.8L builds used for larger tires, locked axles, and demanding trail driving. The performance pump, remote filtered reservoir, and heat-sink cooler address the fluid supply and temperature demands created by repeated steering inputs under load.
Cylinder-assist and full hydraulic options let builders select a pump package for the steering system being installed. The product page lists a pulley-equipped pump, reservoir bracket, hose assemblies, anti-splash valve, cooler, serpentine belt, and PSC 715 fluid. PSC publishes one shared component list rather than a separate bill of materials for each option, so confirm option-specific pump and plumbing details before mixing components. This application is for the 3.8L JK accessory drive, not the later 3.6L engine.
Includes:
- Variant-specific high-flow pump with pulley
- Remote reservoir and mounting bracket
- Hoses, fittings, and anti-splash valve
- Fluid cooler kit and serpentine belt
- PSC 715 power steering fluid

What is included with this SKU?
The Includes section identifies the listed package contents. Where options are offered, choose the matching model year or steering system; do not assume components listed for a different SKU are supplied.
How should the hydraulic system be prepared?
Follow PSC’s installation procedure for system flushing, approved fluid, and thorough bleeding. Confirm hose connections and inspect for leaks before loading the steering system.
Why does steering fluid cooling matter on the trail?
Repeated high-load steering inputs generate heat in the hydraulic circuit. Install the supplied cooler where specified, or plan suitable cooling according to PSC’s recommendations for the complete system.
