Product Description
Upgrade the steering system on your Jeep with the PSC SK689R36JP3-6.75W-1.5 Cylinder Assist Steering Kit, engineered specifically for the 2020-current Jeep Gladiator JT and Jeep Wrangler JL equipped with the 3.6L Pentastar non-eTorque engine. This complete PSC Big Bore XD steering system is designed to dramatically improve steering authority and reliability on vehicles running oversized tires, aftermarket axles, or extreme off-road setups. The PSC Big Bore XD system increases steering power by upgrading the steering gearbox, pump, and assist cylinder to handle the additional load created by large tires and locking differentials. A larger internal piston and upgraded sector shaft design deliver significantly greater steering torque while maintaining smooth steering response and predictable road feel. This complete system includes the PSC Big Bore steering gear, high-output power steering pump, hydraulic assist cylinder, and all necessary hoses and fittings for installation. The weld-on axle clamp system is designed for aftermarket front axles with a 6.75-inch stroke cylinder and 1.5-inch tie rod clamp, making it an ideal solution for serious trail rigs, rock crawlers, and high-performance off-road Jeep builds. When running 37-40 inch tires or locking differentials, steering load increases dramatically. The PSC cylinder assist steering system distributes that load across the steering gear and hydraulic cylinder, reducing stress on the steering box and improving steering precision in the most demanding off-road conditions.
