Product Description
The PSC SK689R36JP2-6.75W-1.5 Cylinder Assist Steering Kit is a complete high-performance steering solution engineered for the 2018-2020 Jeep Wrangler JL and JLU equipped with the 3.6L Pentastar Non-ETorque engine. Built around PSC’s proven Big Bore XD steering gearbox, this kit transforms the JL steering system by replacing the factory electro-hydraulic pump with a reliable mechanical pump while adding hydraulic assist to handle the demands of oversized tires and aftermarket axles. Designed specifically for aftermarket axles with 6.75 inch lock-to-lock travel and a 1.5 inch tie rod clamp, this weld-on steering assist system dramatically improves steering torque and control when running 35-inch or larger tires. The included hydraulic steering cylinder reduces stress on the steering box, frame mounts, and steering linkage while acting as a dynamic steering stabilizer during extreme off-road driving. PSC engineered this kit to eliminate common Jeep JL steering problems including steering play and overheating factory pumps. The upgraded 80mm piston steering gear and 45mm sector shaft provide significantly more strength and steering force than factory components, making this system ideal for rock crawling, overlanding, and aggressive trail builds.
