Fits: 2001 thru 2007 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ Duramax Diesel GM has discontinued steering boxes for a lot of these Duramax trucks. This left everyone with low quality aftermarket replacements that either leaked or had play right out of the box. DmaxStore now has a solution for this with our 100% BRAND NEW steering box with NO CORE CHARGE ! These high quality steering boxes are designed off of the OEM steering box while using ALL brand new parts. They include the latest updated revisions to ensure reliability and longevity. Each individual steering box is bench tested to confirm optimal performance and reliability before it is boxed up, test results are included. These steering boxes still utilize the factory style 3-spline pitman arm, unlike some aftermarket options which will require you to switch to a 4 spline. We have tested many aftermarket options only to come up with dismal results and premature failures. This is the best replacement steering box on the market and we are proud to offer a 3 year warranty for extra peace of mind. Features: 100% BRAND NEW, NO CORE CHARGE! 3 Year Warranty Utilizes factory 3-spline pitman arm Updated OE design with latest revisions available All steering boxes are bench tested with test results Includes: Brand New Steering Gear Sector Shaft Nut and Lock Washer Installation Instructions Optional: GM Pitman Arm Moog XD Pitman Arm Kryptonite Death Grip Pitman Arm DmaxStore Steering Box Hardware Kit DmaxStore Notes: We HIGHLY recommend completely flushing the power steering/hydroboost system before installing ANY new hard parts to prevent contamination failure.

We have had many issues with the redheads leaking shortly after install and that is ultimately what drove us to provide you with this reasonably priced alternative steering gear box.
