Product Description
The PSC SK689R36JP2-6.75W-1.5OS Cylinder Assist Steering Kit is a complete high-performance steering upgrade designed for the 2018-2020 Jeep Wrangler JL equipped with the 3.6L Pentastar Non-ETorque engine. Engineered for serious off-road builds, this PSC system replaces the factory electro-hydraulic steering system with a traditional high-flow hydraulic steering setup capable of handling oversized tires, heavy axle loads, and aggressive terrain. At the heart of this system is PSC’s Big Bore XD-JL steering gearbox, which increases piston size and sector shaft strength to dramatically improve steering torque and durability. This upgrade eliminates the weak factory steering feel common in JL models and provides precise steering control even when running lockers, large tires, or aftermarket axles. This kit includes a 6.75-inch stroke hydraulic assist cylinder, weld-on mounting tabs, and a 1.5-inch offset tie rod clamp designed specifically for aftermarket axles with 6.75 inches lock-to-lock travel. The system also converts the factory electro-hydraulic steering pump to a high-flow belt-driven mechanical pump, eliminating overheating issues while increasing steering power. For Jeep builders running Dana 44 or Dana 60 aftermarket front axles, this PSC cylinder assist system delivers the reliability and steering authority required for large tires and extreme trail environments.
