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.
*Heavy Duty Case. All mounting areas of the BIG BORE XD are beefed up significantly. The BIG BORE XD weighs in 15 pounds heavier than the OE steering gear.
*Improved on road ability is achieved by changing to a slower 16:1 turning ratio.
