Product Description
Upgrade your early Jeep YJ steering system with the PSC SK210 Cylinder Assist Steering Kit, engineered for 1987-1989 Jeep YJ applications running oversized 32 to 38 inch tires. This complete PSC hydraulic assist package is built to reduce steering effort, increase turning force, and relieve stress on the steering gearbox and frame mounts when larger tires, trail obstacles, upgraded axles, and locking differentials push the factory steering system past its limits. The included BIG BORE steering gear delivers improved torque output while maintaining stable road manners and a familiar steering feel, making this kit ideal for trail-driven and street-driven YJ builds alike. The assist cylinder also works like a dynamic steering stabilizer to help control harsh feedback through rough terrain and technical off-road conditions.
This kit includes the major PSC components needed for a serious steering upgrade: a BIG BORE cylinder assist steering gear, high-performance pump kit, 1.75-inch x 6-inch steering assist cylinder kit with mounting hardware, cylinder assist hose kit, and PSC power steering fluid. PSC notes that welding is required for assist cylinder installation, and the factory high-pressure hose or PSC HK2024 universal pump-to-steering-gear hose kit is required but not included. This system is commonly used on 1987-1989 Jeep Wrangler YJ models with AMC 4.2L (258ci), 2.5L (150ci), and related early YJ steering setups depending on build configuration and front axle combination.
