Tech:
The Big Bore XD2 Power Steering Gearboxes require a high flow rate, 1650 PSI Power Steering Pump for the best service life.

• PSC PN PK1853 for 2007-11 Jeep JK 3.8L EGH
• PSC PN PK1858 for 2012-2018 Jeep JK 3.6L Pentastar

High Mileage or Aftermarket Remanufactured OEM power steering pumps DO NOT meet the required flow rate specifications which may result in premature failure of the steering gearbox.

PSC recommends the use of a fluid cooler to prevent catastrophic damage to the power steering pump.

The dimensionally larger size of the Big Bore XD2 series may interfere with some aftermarket track bars.

HEMI Conversions may present tight clearance tolerances if the air conditioning or OEM power steering pump is located on the bottom driver side of the engine.

LS3 Conversions may require modification/clearancing of the alternator bracket.
