IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers’ wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

Installation Notes:

  • Installation time: 6 hours
  • Difficulty level: 3 of 5


The kit works for the front on a dually. The primary issue with dually trucks is the rear u-bolts. We have to confirm axle tube diameter and length required and see if we have a u-bolt available, or, if they will have to be made at a shop near you.

Includes Shocks exactly as pictured
