Product Description
The PSC SK689R36JP2-6.75W-2.0 Cylinder Assist Steering Kit is a complete high-performance steering upgrade designed specifically for the 2018-2020 Jeep Wrangler JL 3.6L Non-eTorque platform running aftermarket front axles and larger tire setups. This advanced steering package combines PSC’s legendary Big Bore XD steering gearbox with a high-flow mechanical pump conversion and hydraulic cylinder assist system to dramatically improve steering control in demanding off-road environments. Factory Jeep JL steering systems struggle when vehicles are equipped with oversized tires, locking differentials, and heavy aftermarket axle assemblies. PSC engineered this kit to eliminate excessive steering effort, improve steering response, and increase torque output while reducing stress on the steering gearbox and frame mounts. The kit features a 6.75-inch stroke hydraulic assist cylinder and a 2.0-inch tie rod clamp, making it ideal for Jeeps equipped with heavy-duty tie rods and aftermarket Dana 44 or Dana 60 style axles. By upgrading the factory steering system with PSC’s Big Bore XD technology, drivers gain improved turning capability, smoother steering feel, and significantly greater durability for extreme trail conditions.

Frequently Asked Questions
What does a cylinder assist steering kit do?
A hydraulic cylinder assist system adds a steering ram connected to the steering linkage. This dramatically reduces steering effort and allows vehicles with oversized tires and locking differentials to steer more easily during off-road driving.
Is this kit required for large tires?
While not mandatory, hydraulic assist steering is highly recommended for Jeeps running 37-inch or larger tires, heavy beadlock wheels, or aftermarket axles because it reduces stress on the steering gearbox and improves turning capability.
Does this kit replace the factory electric steering pump?
Yes. This PSC system replaces the factory electro-hydraulic pump with a belt-driven mechanical pump designed to provide consistent hydraulic pressure and eliminate overheating issues.
Does the kit include everything needed for installation?
The PSC kit includes the Big Bore XD steering gearbox, pump conversion kit, cylinder assist axle kit, tie rod clamp, hoses, fittings, cooler, and fluid required to install the system.
Will this work with a stock JL axle?
This specific configuration is designed for aftermarket axle setups with a 6.75-inch lock-to-lock steering geometry and a 2.0-inch tie rod clamp. Vehicles with stock axles may require different cylinder assist kits.
