PSC 12-Up Jeep JK Extreme Duty Cylinder Assist Kit

PSC Motorsports
PSC JK D44 Hydro Kits

PSC Cylinder Assist systems are engineered to increase the turning force of a Jeep steering system by as much as 50%. If you have installed larger tires, aftermarket axles and/or locking differentials and you can no longer turn your Jeep on the trail? Then a Cylinder Assist system is the answer to your steering woes.

Kit Includes
  • 100% New Steering gear modified for cylinder assist
  • 100% New Power Steering Pump with pulley
  • Remote PS fluid reservoir with serviceable filter
  • All required hoses and fittings
  • Steering Cylinder
  • All steering cylinder mount brackets bolt straight onto the stock axle housings and tie rods with the use of a few hand tools.

The steering gearbox in this particular kit retains the stock OEM valving. This valving allows the handling to remain as close to the way the vehicle was engineered to be as possible. You will have decent road feel on the highway and no over steer. The steering input effort will remain un-altered from stock at all speeds. The steering assist will increase the actually turning force of the steering components without changing the effort of what the driver physically has put forth. This kit is highly recommended for the customer that drives their vehicle daily on public roads.

If you should choose to use a reduced effort steering gear / cylinder assist kit, the drivability at highway speeds can be adversely affected. Also a note of caution, if you vehicle has poor handling characteristics before installing light valved cylinder assist system, the handling will be even more adversely effected. For that reason light valved steering kits are recommended for vehicles that are built for the offroad and rarely driven on public roads. Cylinder assist systems will not correct poor on road steering characteristics.

PSC recommends Swepco 715 Power Steering Fluid in all PSC Systems

Don't forget to flush your system!
