Product Description
The PSC SK689R36JP3-8.0W-1.75 Cylinder Assist Steering Kit is a complete high-performance hydraulic steering upgrade designed for 2020+ Jeep Gladiator JT and Jeep Wrangler JL/JLU equipped with the 3.6L Pentastar Non-eTorque engine. Built around PSC’s legendary Big Bore XD steering gearbox, this system eliminates the weaknesses of the factory electro-hydraulic steering system and replaces it with a robust mechanical hydraulic steering setup capable of handling aggressive off-road conditions. This kit is specifically configured for aftermarket 8.0-inch lock-to-lock axles and includes a powerful 8-inch stroke hydraulic steering assist cylinder with weld-on mounting tabs and a 1.75-inch tie rod clamp. The system dramatically improves steering control when running oversized tires, locking differentials, and high articulation suspension systems. PSC engineered this steering system to eliminate excessive steering play, prevent pump overheating, and provide the torque needed to steer vehicles equipped with 35-37 inch tires or larger. The included high-flow mechanical pump conversion replaces the factory electronic pump system, delivering reliable hydraulic power even during extreme off-road use. Whether your Jeep is built for rock crawling, overlanding, or hardcore trail use, the PSC SK689R36JP3-8.0W-1.75 steering kit provides the durability and steering precision required for demanding terrain.

Frequently Asked Questions
What does a cylinder assist steering kit do?
A cylinder assist steering system adds a hydraulic steering ram connected to the tie rod. This dramatically reduces steering effort and improves control when running large tires or heavy off-road loads.
Why upgrade the Jeep JL/JT steering system?
The factory electro-hydraulic steering system can struggle with large tires and heavy off-road use. PSC’s mechanical hydraulic pump conversion and Big Bore XD steering gearbox provide stronger and more reliable steering performance.
Does this kit work with factory axles?
This version of the kit is designed for aftermarket front axles with 8.0-inch lock-to-lock steering geometry. Additional components may be required for factory axle setups.
What tire sizes benefit from this system?
This steering system is commonly used on vehicles running 35-37 inch tires or larger, especially when combined with lockers and off-road suspension systems.
Is welding required to install this kit?
Yes. The steering assist cylinder mounts require weld-on tabs for proper installation and strength.
