Description

Add the Driven Diesel DD-DMX-PS-KIT Power Steering Line Kit from XDP and upgrade your 2001-2010 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax (With Hydroboost Braking System). The factory power steering hoses in the hydroboost equipped 2001-2010 Chevy/GMC Duramax trucks are notorious for leaks. Many of the available replacements for these hoses have not been improved, with some of of them starting to leak again not long after installation. Driven Diesel decided to produce a completely new set of replacement power steering hoses that addresses the problems with the OEM parts. 

The Driven Diesel power steering hose assemblies are not only manufactured from superior materials, but were also designed to be easier to install and serviceable in the unlikely event of a leak. Unlike the factory design, the hydraulic hose is no longer permanently attached to the tubing sections, one of the major downfalls of the stock lines. Instead, the Driven Diesel tubing sections have been fitted with AN fittings, making the hydraulic hose portion of the line removeable and replaceable. This aids installation by allowing the tubing sections to be installed independently of the hose and allows replacement of the hydraulic hose without having to purchase the expensive tubing sections again. Featuring Stainless Steel tubing sections, these hoses are rated for 4,000 psi working pressure. Best of all, the hose bends are patterned after the OEM hoses providing a factory fit.

Features:
  • Hose is Made in USA
  • Flame Resistant Outer Jacket
  • Tubing Sections are Stainless Steel
  • Rated for 4,000 psi Working Pressure
  • Will Not Make Power Steering Pump Louder
  • 100% Brand New CNC Bent Tubing Sections
  • Patterned After OEM Bends for a Factory Fit
  • No Reused Factory Parts & No Cores to Return
  • Manufactured with Standard 37-degree AN Fittings
  • Kit Replaces Only the 2 Pressure Hose Assemblies
  • All Bending, Flaring and Assembly Performed in USA
Note:
This kit does not include low-pressure return hoses.
Trucks with a 3” or more of body lift will require custom hoses.
Please check your hoses carefully during installation, as the warranty does NOT cover damage from being improperly installed. If the lines have too much tension, it will eventually damage one of the hoses.

Nice kit
Burke (Lincoln, Ne) | September 21st, 2025
This is a very nice kit. Gets rid of the factory leak prone lines. Went together very nice. Build quality is great. The lost star is because I think the rubber parts are about an inch too long to work nicely with the hard pieces. I had to kind of force them into place if they were both about an inch shorter they would have lined up perfectly without fighting with them to not push on stuff around them.

Good lines but not a complete set!
Brandon (Boston, MA) | June 8th, 2023
When purchasing I failed to read that it did not include the low pressure return line on the steering box. Did not realize this mistake until I went to install.
