Need a more responsive feeling when you turn the wheel? Steering components over time wear down like anything else in your truck which can give you excessive play in your steering wheel or require more effort when you try to turn. Whether you are planning on upgrading or you want to steer with confidence, PSC's BIG BORE XD is the steering gear built to take what the road throws at it. Engineered to handle the increased torque loads of performance and off-road vehicles, the PSC XD shaft is fully updated with a larger diameter sector shaft so you won't get oversteer but instead get a familiar feel of the road. Fix your steering and prepare for future PSC upgrades with the BIG BORE XD that gives you greater value and peace of mind over re-manufactured components. This version of BIG BORE XD comes with Cylinder Assist functionality so if you're planning on upgrading to a PSC Steering Assist Cylinder this is the one for you!
