Product Description
The PSC SK688R38JP1-OE-2.0 Cylinder Assist Steering Kit is a complete hydraulic steering upgrade engineered for the 2007-2011 Jeep Wrangler JK/JKU equipped with the 3.8L engine and OE front axle. Designed for serious off-road performance, this system combines PSC’s legendary Big Bore XD steering gearbox, high-flow steering pump, and hydraulic assist cylinder to dramatically improve steering power and control. Oversized tires, locking differentials, and extreme terrain can overwhelm the factory steering system. The PSC SK688R38JP1-OE-2.0 system solves those issues by increasing steering torque output while reducing steering effort. The kit includes a 6.75-inch stroke hydraulic assist cylinder and a 2.0-inch tie rod clamp, providing the strength required for Jeeps running 35-44 inch tires. PSC engineered this kit as a complete bolt-on solution that includes everything required for installation. The upgraded pump, cooler, and high-pressure hoses ensure consistent hydraulic pressure and reduced fluid temperatures during demanding off-road conditions. Whether you're rock crawling, trail riding, or building a high-performance Jeep JK, this PSC steering kit delivers precise control and unmatched durability.
