Description

NOT SURE WHICH OPTIONS TO CHOOSE? CALL US AT 608-481-2789 OR EMAIL SALES@BOSCHMASSPEEDSHOP.COM BEFORE ORDERING.

Run a true drag radial setup on your 2024-2026 S650 Mustang GT. We modify your existing knuckles to clear wheels up to 15x11, so you can get a 15" wheel and tire combo under your car.

Choose your setup

  1. Select your Knuckles option: send us your existing knuckles, have us source used knuckles, or choose brand new S550 knuckles with bearings.
  2. Select your GT500 parts option. Choose None if you do not need GT500 parts, an individual part, a two-part combination, or All three for the axle conversion, used stock axles and new axle bearings.
  3. The displayed price is the total for your selected combination. Add your complete selection to the cart once. Shipping is additional.

GT500 parts are optional, not required for every Mustang. Please inquire about your exact combination before ordering, especially for GT500, GT350 and Performance Pack cars.
