Description
The XDP Stock+ Power Steering Gearbox (New) XD748 is an ideal replacement for the worn steering gear in your Chevy Silverado or GMC Sierra 2500HD/3500HD. The most common cause of a failing steering gearbox (also known as a
steering gear or steering box) is long-term wear and tear. Over time,
internal components such as the worm gear, sector gear, and bearings can
wear down or get damaged. Other contributing factors may include rough
road conditions, potholes, and fluid leaks.
Symptoms
of a worn steering gearbox include a leaking sector shaft seal,
excessive play in the steering wheel (loose or unresponsive steering),
or the vehicle wandering or pulling while driving. Other signs to watch
for are difficulty turning, leaking fluid, a stiff steering wheel, and
grinding or clunking noises coming from the steering system. As the
condition worsens, you may also notice that more effort is required to
steer, especially at lower speeds or when maneuvering.
New, Not Remanufactured
Built with 100% new components, the XDP Stock+ Power Steering Gearbox is designed to provide you with a long and dependable service life. Each unit features a bolt-on design and is designed to work with the factory pitman arm and steering shaft.

Great Gearbox reduced my steering play.
matthew (KS) | May 2nd, 2026
After replacing my front end, I had a lot of play left at my steering gearbox. From recommendations, I bought a Redhead gearbox however, the play was still there even after sending it back and getting a new one. This gearbox fixed the play(along with the kryptonite pitman arm) Great customer service and quick shipping.
