Product Description
Upgrade your Jeep’s steering system with the PSC PK38JP1 Power Steering Pump Reservoir and Cooler Kit, engineered specifically for 2007-2011 Jeep Wrangler JK 3.8L engines running PSC SG688/R Big Bore XD steering gearboxes. This complete steering pump system provides the increased pressure and fluid flow required for demanding off-road conditions, oversized tires, and hydraulic assist steering systems. PSC designed the PK38JP1 kit to deliver improved steering performance under extreme loads where factory steering pumps struggle to keep up. The high-flow performance pump combined with a remote reservoir, fluid cooler, and high-quality hoses ensures stable steering pressure while preventing overheating during aggressive off-road use. This complete kit includes everything needed to support high-performance steering systems including pre-assembled hoses, mounting brackets, pulley, hardware, and SWEPCO 715 power steering fluid. The large-capacity reservoir helps maintain proper fluid levels during rapid steering cycles commonly seen in rock crawling, trail riding, and heavy off-road driving.
