This is a trailing arm champ sled built by Wahl Brothers Racing. This was pretty much stripped of all the components when I purchased the chassis so all the replacement parts are new, never run. It has a new tunnel, "R" track, new Wahl champ suspension with upgrades, new champ skis, new drive axle with anti slip drivers, new hood and windshield, updated steering pitman and idler arms, 440 pro x motor with a reprogrammed CDI (10,000 rpm), etc. This sled needs to be finished assembling with the new items. Would make a nice low cost champ sled that could be setup for numerous classes.
