Product Description
The PSC SK689R36JP2-6.75W-1.75 Cylinder Assist Steering Kit is a complete hydraulic steering upgrade engineered specifically for 2018-2020 Jeep Wrangler JL/JLU models equipped with the 3.6L Pentastar Non-ETorque engine. Built around PSC’s legendary Big Bore XD steering gear, this system dramatically increases steering torque and eliminates the weak points found in the factory JL electro-hydraulic steering system. Designed for rigs running aftermarket 6.75-inch lock-to-lock axles and large off-road tires over 35 inches, this kit includes a heavy-duty 6.75-inch stroke steering assist cylinder, weld-on mounting tabs, reinforced hydraulic lines, and a robust 1.75-inch tie rod clamp. The hydraulic assist cylinder reduces steering effort while simultaneously acting as a dynamic stabilizer, providing improved control in rocks, mud, sand, and extreme trail conditions. PSC engineered this system to withstand the extreme loads created by oversized tires, locking differentials, and aftermarket axle upgrades. By increasing piston size and sector shaft strength inside the steering gear, the Big Bore XD system provides significantly improved steering feel, durability, and reliability compared to the factory JL steering system. Whether you're building a hardcore rock crawler, overland Jeep, or high-performance trail rig, the PSC SK689R36JP2-6.75W-1.75 steering system delivers the torque, precision, and durability required for serious off-road performance.
