XDP STOCK+ POWER STEERING GEARBOX (NEW) XD748 | 2011-2021 6.6L DURAMAX

Restore precise steering control in your Chevrolet Silverado or GMC Sierra 2500HD/3500HD with the XDP Stock+ Power Steering Gearbox XD748. Designed as a direct-fit replacement for a worn or damaged factory steering gearbox, this upgraded unit helps restore steering responsiveness, control, and dependable operation.

Over time, internal steering gearbox components such as the worm gear, sector gear, and bearings can wear due to normal use, rough road conditions, and fluid leaks. Common symptoms of a failing steering gearbox include excessive steering wheel play, vehicle wandering, difficulty turning, fluid leaks, and unusual grinding or clunking noises.

Unlike remanufactured steering gearboxes, the XDP Stock+ Power Steering Gearbox is manufactured using 100% new components for dependable performance and long service life. Its direct-fit, bolt-on design maintains compatibility with the factory pitman arm and steering shaft, simplifying installation without requiring custom modifications.

Each gearbox is completely new and requires no core charge, eliminating the need to return your original steering gearbox.
