Upgrade your Jeep Wrangler JL’s steering performance with this heavy-duty PSC Cylinder Assist Steering Kit, engineered specifically for 2018–2023 3.6L Pentastar models. Factory electro-hydraulic systems on the JL often struggle under the stress of big tires, off-road abuse, and aftermarket axles. PSC’s solution enhances power and precision where it matters most.
Key Features & Benefits:
-
Big Bore XD Steering Gearbox: Replaces the weak OE unit (42 mm) with a reinforced 45 mm sector shaft and 80 mm (70→80 mm) piston for dramatically increased torque capacity
-
Belt‑Driven High‑Flow Pump Conversion: Replaces stock electric pump to prevent overheating and deliver consistent hydraulic pressure
-
6.75″ Stroke Assist Cylinder: Mounted on the axle, this ram dramatically lowers steering effort, enhances on-center control, and improves locked-diff turning
-
Complete Hardware Package: Includes upgraded hoses, cooler, reservoir, SWEPCO fluid, pitman arm, tie‑rod clamp options, and mounting brackets tailored for OEM or aftermarket axles.
Whether tackling technical trails, rock crawls, or daily highway driving with oversized tires, this kit eliminates steering “play,” prevents pump burnout, and delivers predictable control—even when lockers are engaged. A Tazer JL or similar programmer is required to override OE EHPS functions and enable the belt-driven pump setup
