Product Description
The PSC SK689R36JP3-6.75W-2.0 Cylinder Assist Steering Kit is a complete high-performance hydraulic steering upgrade engineered specifically for 2020-Present Jeep Gladiator JT and Wrangler JL models equipped with the 3.6L Pentastar non-eTorque engine. Designed to address the limitations of the factory electro-hydraulic steering system, this PSC Big Bore XD kit delivers dramatically increased steering torque, improved control with oversized tires, and superior durability for demanding off-road conditions. PSC designed the Big Bore XD steering system from the ground up using a traditional belt-driven mechanical power steering pump paired with a heavy-duty steering gearbox and hydraulic assist cylinder. This setup eliminates common factory steering issues such as pump overheating, steering play, and inconsistent steering feel when larger tires or locking differentials are installed. This specific configuration includes a 6.75-inch stroke hydraulic assist cylinder and a 2.0-inch tie rod clamp for vehicles running heavy-duty aftermarket front axles and steering components. The weld-on mounting configuration allows for maximum steering assist strength and precise control when crawling rocks, navigating technical terrain, or handling aggressive off-road builds. For Jeep owners running 37-inch or larger tires, aftermarket axles, or high-performance off-road suspensions, the PSC SK689R36JP3 steering kit delivers the steering torque and reliability needed to maintain precise vehicle control in extreme environments.

Frequently Asked Questions
What does the PSC cylinder assist steering kit do?
A cylinder assist steering kit adds a hydraulic steering ram to help the steering gearbox turn large tires and heavy off-road setups. This significantly reduces steering effort and improves steering control during rock crawling or aggressive off-road driving.
Why upgrade the factory Jeep JL / JT steering system?
The factory electro-hydraulic steering system can struggle with oversized tires and aftermarket axles. The PSC Big Bore XD system replaces the factory pump and steering components with a stronger mechanical steering system that produces significantly higher steering torque.
Does this kit work with aftermarket axles?
Yes. This specific kit is designed for vehicles running aftermarket front axles and heavy-duty steering components using a 2.0 inch tie rod configuration.
Is welding required for installation?
Yes. This kit uses a weld-on cylinder assist mount that must be installed on the axle housing for proper alignment and steering performance.
What tire sizes benefit most from hydraulic assist steering?
Hydraulic assist steering is commonly recommended for vehicles running 37-inch or larger tires, locking differentials, beadlock wheels, and heavy off-road suspension systems.
