Product Description
The PSC SK689R36JP2-OE Cylinder Assist Steering Kit is a complete hydraulic steering upgrade engineered for the 2018-2020 Jeep Wrangler JL equipped with the 3.6L Pentastar Non-eTorque engine. Designed specifically for vehicles running OE front axles and factory tie rods, this PSC system dramatically improves steering strength, reliability, and control for Jeeps running oversized tires or tackling demanding off-road terrain. PSC developed the Jeep JL Big Bore XD steering system to solve the steering limitations found in the factory electro-hydraulic steering system. This kit replaces the factory pump with a high-flow mechanical power steering pump while adding a hydraulic assist cylinder and PSC Big Bore XD steering gearbox to dramatically increase steering torque and control. With a 6.75-inch stroke steering cylinder, upgraded hoses, remote reservoir, and fluid cooler, the SK689R36JP2-OE kit delivers exceptional steering authority when running larger tires, locking differentials, or tackling difficult rock crawling environments. The bolt-on cylinder mounts allow installation without tie-rod clamps, making this one of the most complete and reliable steering upgrades available for the Jeep JL platform.
