    Big Bore XD Steering Gear Box for JK

    The PSC Motorsports Big Bore XD Steering Gear Box is designed to provide your Jeep Wrangler JK with a direct replacement for your 70mm stock piston. This kit uses a larger 80mm piston, giving it more turning torque to turn up to 37" tall tires without the need of cylinder assist. The sector shaft diameter is increased from 35mm to 42mm for a 35% increase in strength. More material was added to the case in all mounting, providing a sturdier base. This is a must-have for anyone running bigger than factory tires.

    1. turns with one finger  star rating

      install was a pain. instructions were lacking from pcs but a quick Google search and a YouTube video later and it's not that hard to install. off-road elements has the write up on how to bleed the system. turns my 35's no problem. was actually scary at first jeep responds like a normal vehicle instead of hand over handing turns. steering feels solid now and if ya get it the pitman arm bolt is 1 5/8th massive thing. I no longer fear the steering box snapping like the one one
