Product Description
The PSC SK689R36JP2-6.75W-1.625 Cylinder Assist Steering Kit is a complete high-performance hydraulic steering upgrade engineered specifically for the 2018-2020 Jeep Wrangler JL/JLU equipped with the 3.6L Pentastar Non-ETorque engine. Designed to eliminate factory steering limitations when running oversized tires and aftermarket axles, this system dramatically increases steering torque, control, and durability. At the core of the system is the PSC Big Bore XD steering gearbox, featuring an upgraded 80mm piston and a larger 45mm sector shaft for increased strength and steering power. This allows drivers to confidently turn larger tires, even when differential lockers are engaged or during extreme off-road articulation. The kit also replaces the factory electric steering pump with a reliable belt-driven hydraulic pump system, delivering consistent steering performance under demanding trail conditions. A 6.75-inch stroke hydraulic assist cylinder with weld-on tabs provides additional steering force to handle vehicles equipped with aftermarket axles and large tires exceeding 35 inches. Complete with hoses, fittings, cooler, reservoir system, and SWEPCO power steering fluid, the PSC SK689R36JP2 steering kit delivers one of the most advanced steering solutions available for Jeep JL builds focused on rock crawling, overlanding, and high-performance off-road driving.
