Product Description
The PSC SK689R36JP3-8.0W-1.5 Cylinder Assist Steering Kit is a complete heavy-duty steering solution engineered for 2020-current Jeep Gladiator JT and Wrangler JL models equipped with the 3.6L Pentastar Non-ETorque engine. Designed specifically for vehicles running aftermarket axles and oversized tires, this kit delivers dramatically improved steering torque, reduced steering effort, and superior control in extreme off-road environments. At the heart of this system is PSC’s Big Bore XD steering gearbox, designed to eliminate factory steering issues commonly found in modern Jeep electro-hydraulic steering systems. The included 8.0-inch stroke hydraulic assist cylinder works alongside the upgraded mechanical pump system to provide the hydraulic power required to turn large tires and heavy off-road setups with ease. This weld-on steering kit is designed for aftermarket 8.0 lock-to-lock axles and 1.5-inch tie rods, making it a popular upgrade for high-performance trail rigs, rock crawlers, and serious off-road builds. By converting the factory steering system to a traditional belt-driven high-flow hydraulic steering setup, PSC eliminates the overheating and steering play often experienced with factory electro-hydraulic steering systems.

Frequently Asked Questions
What does a PSC cylinder assist steering kit do?
A cylinder assist steering kit adds a hydraulic steering cylinder that works with the steering gearbox to dramatically increase steering torque. This allows vehicles with large tires, lockers, and heavy off-road setups to steer easily in demanding terrain.
Why upgrade the factory Jeep JL or JT steering system?
Factory electro-hydraulic steering systems can struggle with larger tires and heavy off-road use. PSC’s Big Bore XD steering system converts the steering to a high-flow hydraulic system that improves steering response and durability.
Is this kit compatible with factory axles?
This specific kit is designed for vehicles running aftermarket axles with an 8.0 inch lock-to-lock measurement and a 1.5 inch tie rod system.
Will this kit work with tires larger than 35 inches?
Yes. The PSC hydraulic assist steering system is commonly used on Jeeps running 37-40 inch tires where additional steering torque is required.
Does this kit include everything needed for installation?
Yes. The PSC steering kit includes the Big Bore XD steering gearbox, steering cylinder, pump conversion components, hoses, fittings, and mounting hardware required for installation.
