ST Racing Concepts MIP C-CVD Kit. Are you ready to throw in some serious horsepower in your Traxxas Slash? If you're ready to toss that kit motor and move out of the spec class, be sure your Traxxas Slashs transmission is ready for it by replacing the kit plastic driveshaft with a set of ST Racing Concepts new MIP C-CVD Kit. ST Racing Concepts has teamed up with one of the best manufacture in the business and MIPs multiple World Championships and National Championship winning design CVD can now be part of an important upgrade to your Traxxas Slash. The new C-CVD style design eliminates the original set-screw over drive pin design and instead utilizes a unique screw-on outer C-Ring that captures the drive pin in place. The CVD bones are also constructed of larger diameter (more material) for even more durability. Comes complete with a pair of beefy steel diff outdrives as well. Also works on Nitro Stampede and Nitro Rustler (not applicable to electric versions).
