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.

WHAT IS THE DIFFERENCE BETWEEN SUPERLIFT  AND BILSTEIN SHOCKS?

Superlift shocks are twin tube, velocity sensitive hydraulic shocks. Bilstein shocks are a mono-tube gas pressurized shock. The Superlift shocks are coated with a white paint; the Bilstein shocks are a brushed steel body with a nickel and clear zinc finish. Bilstein shocks are more tuned for the application and offer more precise valving.

 

DOES IT WORK ON A DUALLY?

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.
