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 time: 8 hours
  • Difficulty level: 4 of 5



The drop bracket kits utilize brackets to relocate the upper control arms and require brackets to relocate the steering assembly. Bracket style kits do not increase the front track width but do require a replacement front driveshaft. The knuckle kits use a new knuckle to span the distance between the upper control arm and lower control arm. The steering correction is also built into the replacement knuckles with the tie rod boss being higher versus the stock knuckle. Knuckle kits are easier to install but require aftermarket wheels due to the increased size of the knuckles. Knuckle kits do not require a replacement front drive shaft.



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.
