Product Description
The PSC SK689R36JP2-8.0W-2.0 Cylinder Assist Steering Kit is a complete high-performance steering upgrade engineered for 2018-2020 Jeep Wrangler JL models equipped with the 3.6L non-eTorque engine and an aftermarket front axle. Designed for serious off-road use, this PSC Big Bore XD steering system delivers dramatically improved steering control, increased torque output, and superior reliability when running oversized tires or locking differentials. PSC designed this kit to eliminate the common steering issues experienced with factory JL steering systems, including steering play, weak steering torque, and overheating electro-hydraulic pumps. The system replaces the factory setup with a high-flow belt-driven power steering pump, Big Bore XD steering gearbox, and hydraulic assist steering cylinder, creating a steering system capable of handling extreme loads from large tires and aggressive off-road terrain. This configuration includes a weld-on cylinder assist mount designed for 8.0 inch lock-to-lock aftermarket axles and a 2.0 inch tie-rod clamp, making it ideal for heavy-duty axle swaps and high articulation suspension setups. The hydraulic assist cylinder acts as both a steering aid and dynamic stabilizer, significantly reducing stress on steering components while improving turning ability under load. Whether you're building a trail-ready JL or a dedicated rock crawler, the PSC SK689R36JP2-8.0W-2.0 steering kit provides the durability, precision, and power required to handle extreme off-road conditions.

Frequently Asked Questions
What does a cylinder assist steering kit do?
A cylinder assist steering system adds a hydraulic ram to the steering linkage that assists the steering gearbox when turning large tires or operating under heavy off-road loads.

No. This version is designed specifically for vehicles running an aftermarket front axle with approximately 8 inches of lock-to-lock steering travel.
Does this kit include everything required for installation?
Yes. The PSC kit includes the steering gearbox, hydraulic assist cylinder, high-flow pump, hoses, fittings, and mounting hardware for a complete steering system upgrade.
What tire sizes can this kit support?
