RECOMMENDED INSTALLATION NOTES:
The BIG BORE XD2 Steering Gearbox was designed to be used with a power steering pump capable of 1800 PSI.
PSC highly recommends the use of their HIGH FLOW/HIGH-PRESSURE Pump Kits to ensure system efficiency and extend component life. These pumps operate at approximately 1800 PSI and produce 50% more volume than the OEM pump. Vehicle steering performance will be diminished if a high mileage or remanufactured component is used.
PSC recommends the use of a power steering fluid cooler and SWEPCO 715 Power Steering Fluid.
The larger size of the BIG BORE XD2 Steering Gearbox may prohibit the use of some aftermarket track bars.
Pitman Arm Retaining Nut Size: 46MM
HEMI Engine Conversions: If the AC compressor or power steering pump is located on the bottom driver side of the engine, there may be clearance issues.
