This is an optional ST Racing Concepts Heat Treated Steel Driveshaft Kit, and is intended for use with the Traxxas Slash, as well as the Nitro Slash. Carrying over design and material selection from the HPI Blitz and Associated SC10 universal kits, the ST Racing Slash 2wd universal kit features a large diameter universal driveshaft bone for more durability against the power of today's Lipo battery and Brushless motors, as well as the heavier weight of short course trucks and the larger diameter of the tires.
ST Racing also used the same carbon steel material for the axles, which features two sets of universal pin holes so you can get twice the life out of the same set of axles. The universal joints and joint pins are of carbon steel material as well and the pins features a "step" for the setscrew to have a flat spot to more securely hold the universal driveshafts together. Lastly, even the universal shaft roll pin at the end was not over looked. Carbon steel at the pin although strong will unfortunately add excessive wear to the diff outdrives, thus a different material was selected just for the shaft pin for durability and ease of wear on the diff outdrives.
SPTST1953X components are NOT compatible with the previous ST1953 universals.
