With this kit, you'll be able to convert a Hustler, Bandit, Stampede or Slash 2wd chassis to a solid rear axle platform to use on any build that benefits on this type of suspension, like a drag racer, desert truck, rat/hot rod, and many more! Besides your Traxxas 2wd chassis, you'll need a suitable rear axle for your application (Axial SCX10 for narrow rear ends, AX10 or RR10 for wider ones), a assortment of screws, many can be used from the unused chassis parts of your donor car, and a LOT of patience to print and build it.
