Description

PSC's JK Big Bore XD steering gear box replaces the 70mm stock piston with a larger 80mm piston, giving it more turning torque to turn up to 37 in. tall tires without the need of cylinder assist. More material was added to the case in all mounting for a sturdier base. The sector shaft diameter was increased from 35mm to 42mm for a 35 percent increase in strength. PSC JK Big Bore XD kits come with a factory drop pitman arm, nut, and washer to match the newer larger sector shaft. Anyone with a Jeep JK running larger than factory tires will want this bolt-on upgrade on their must have list!
