Overview
PSC Jeep JL/JT Cylinder Assist Big Bore XD Steering Kits
Many late-model Jeeps are equipped with new computer controlled electro-hydraulic steering (EHPS), electronic stability control (ESC), electronic roll mitigation (ERM), and a weight-saving aluminum housing steering gearbox. PSC has taken the Jeep steering system back to the drawing board and engineered its exclusive Big Bore XD steering gearbox and a traditional belt-driven high-flow mechanical power steering pump conversion. This produces an essential upgrade to solve the undesirable factory steering performance, while efficiently handling the increased torque loads due to larger tire sizes and installing aftermarket axle assemblies.
Typical benefits:
* Eliminates excessive on-center steering wheel “play”
* Eliminates electro-hydraulic pump overheating
* Increased torque output turns tire sizes over 35 in.
* Improved turning capability when locking differentials are engaged
Depending on model, kits can contain:
* Big Bore XD steering gearbox
* High-flow mechanical pump conversion kit
* Reservoir kit
* Upgraded high-pressure hose assembly
* Upgraded return line kit
* Fluid cooler kit
* SWEPCO 715 power steering fluid
