Features & Product Details

The New BIG BORE XD JK steering gear is the most powerful and strongest replacement Jeep JK steering gear on the market. Anyone with a Jeep JK running large tires and/or has a locking front differential will want this bolt on upgrade on there must have list.

*The BIG BORE XD produces up to 35% more turning force than the OE steering gear. By replacing the stock 70mm piston assembly to a larger 80mm piston, output torque is increased significantly. This is the same piston assembly found in all new Ram 2500/3500 diesel trucks. The increased turning torque will turn up 37" tall tires without the need of cylinder assist.

*Changed also is the sector shaft diameter. This has been increased from 35mm to 45mm to handle the extra torque output. Included in the kit is a new pitman arm that mates to the larger sector shaft. Note the pitman arm is a OE replacement and has no extra drop to it.

Recommended Installation notes.

The BIG BORE XD was engineered for use of a high-pressure pump-1800 PSI. PSC highly recommends the use of their HIGH FLOW/PRESUURE pump kits designed for BIG BORE XD applications. These pumps operate at 1800 psi and produce 50% more volume per revolution than the OE pump. The factory OE steering pump operates at 1500 PSI and will operate the system, however you will not be benefiting from the full potential of the steering gear. Steering could feel worse if your OE steering pump has been overheated or has high mileage. Always use a power steering fluid cooler and PSC recommended power steering fluid.

The larger size of the BIG BORE XD may interfere with some aftermarket track bars.

Hemi engine conversions-if your AC or power steering pump is on the bottom drivers side of the engine,there might be some clearance issues.

LS3 Conversions-the alternator will need to modified for clearance

Even though this gear is huge next to the stock one, it truly does just drop right in. Performance is right on; easy steering with 35's yet does not oversteer or take away from steering feedback. The price is also great when you consider a replacement O.E.M. is only $100 less. For a little extra, it is well worth the comfort of having something much stronger than the original.

QUESTIONS & ANSWERS

  • Q: What is the difference between this and the PSCSG688R?  2 days ago

    I am looking at this and comparing it to the PSCSG688R and I am unable to tell the difference. What is the difference between the two? Also, can I just run the PSCSG688 and wait to upgrade the steering pump and add a cooler or am I asking for trouble?
    • 0 of 0 people found the following answer helpful

      A:  The SG688R is the ported box, for use with hydro assist. The SG688 "can" be installed by itself, but it is highly recommended not to do so. From PSC: "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."
