Product Description
Upgrade your Jeep’s steering strength and control with the PSC SG061R BIG BORE XD Cylinder Assist Steering Gear. Designed specifically for 1987-2002 Jeep YJ and XJ platforms, this heavy-duty steering gearbox features PSC’s BIG BORE XD internal design with a larger piston diameter to dramatically increase steering torque output. This upgrade allows vehicles running oversized tires, locking differentials, and extreme off-road setups to maintain precise steering control even under heavy load. Unlike stock steering boxes that struggle with modern off-road builds, the SG061R is engineered with billet aluminum top and end caps, reinforced internal components, and precision machined assist ports to support hydraulic steering assist systems. The assist ports are threaded directly into the housing for secure -6AN hose connections, eliminating weak welded fittings and improving long-term durability for aggressive trail use. With a variable turning ratio and improved hydraulic efficiency, the PSC SG061R delivers smoother steering response, reduced steering effort, and improved vehicle control whether you are rock crawling, trail riding, or driving on the street.

Frequently Asked Questions
What makes the PSC SG061R steering gear different from stock?
The SG061R uses a larger internal piston and upgraded components to increase steering torque output. This allows vehicles with large tires or locking differentials to steer much easier than with a factory steering box.
Does the PSC SG061R support hydraulic steering assist?
Yes. The gearbox includes integrated assist ports that allow direct connection to PSC hydraulic steering assist cylinders using -6AN fittings.
Is this steering box a direct replacement?
Yes. The PSC SG061R installs in the factory steering box location and uses the factory mounting pattern, making it a direct replacement for stock steering gears on compatible Jeep models.
What tire sizes benefit from this upgrade?
Vehicles running 33-40 inch tires, locking differentials, or heavy off-road builds benefit significantly from the increased steering torque provided by the BIG BORE XD design.
Can this be used without a steering assist cylinder?
Yes. The gearbox will function as a standalone heavy-duty steering gear, but it is designed to work optimally when paired with a PSC hydraulic steering assist cylinder system.
