PSC's Exclusive Big bore XD2 Power Steering Gearbox is an essential, critical steering component for any Jeep JK with increased torque loads such as large tire sizes up to 37", locking front differentials, and larger aftermarket axles such as Currie, Dynatrac, and Teraflex.

The Big bore XD2 Power Steering Gearboxes require a high flow rate, 1650-1800 psi Power Steering Pump for the best service life.
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.

LS3 Conversions may require modification/clearancing of the alternator bra
