Description

If you’ve got a JL 392 and big tires, you already know the factory steering just doesn’t cut it. Whether you’re running stock axles or a full aftermarket setup, PSC’s Cylinder Assist Steering Kits are built to handle the power of the HEMI and the punishment of off-road driving.

These kits come fully assembled with all the hoses, fittings, brackets, and hardware you need for a clean install. You’ll get our specially valved High Performance Steering Gear with PSC’s High Flow Tower and custom spool valve, plus an upgraded pump designed to keep up with the demands of the cylinder assist system.

We also include a high-capacity remote reservoir, high-flow heat sink cooler, anti-splash valve, and PSC 715 High-Performance Power Steering Fluid. It’s everything you need to upgrade your steering and keep it rock-solid on the trail and smooth on the street.
