Product Description
Upgrade the steering system in your Jeep with the PSC SK689R36JP3-8.0W-1.25 Cylinder Assist Steering Kit. This high-performance steering system is engineered for 2020+ Jeep Gladiator JT and Jeep Wrangler JL/JLU equipped with the 3.6L Pentastar Non-ETorque engine running aftermarket axles and crossover steering setups. PSC developed this system to address the limitations of the factory electro-hydraulic steering system found in modern Jeeps. The kit replaces the factory steering configuration with PSC’s proven Big Bore XD steering gearbox and high-flow hydraulic steering system, delivering dramatically improved steering torque, enhanced control, and superior reliability when running oversized tires and heavy off-road setups. The included 8.0-inch stroke hydraulic assist cylinder and weld-on axle tabs allow this system to handle the increased loads created by aftermarket axles and large off-road tires. With improved steering authority and reduced strain on steering components, this PSC steering kit is ideal for rock crawling, overland builds, and high-performance off-road vehicles. Each kit includes a steering gearbox, hydraulic assist cylinder, steering pump, reservoir, hoses, fittings, and installation hardware to provide a complete hydraulic steering upgrade system.
