This is an optional Team Integy Traxxas 2wd Front Sled Ski Conversion Set. If you drive your Traxxas Slash, Stampede, Rustler or Bandit in the sand or snow, you owe it to yourself to bolt on this Front Sled Conversion. The sleds feature spring-loaded, anodized legs, combined with molded ski's with replaceable front braces and retainers that simply bolt onto your front axles. Combine these with the Integy Snowmobile & Sandmobile Conversion Kit (INTT8633) for the ultimate sand and snow rig.
