that's the hotbodies truck; that is really a truggy platform and the best upgrades you could make would be lipo receiver pack, faster steering servo, tires, and other things that make it more durable or handle better. if the diffs don't have oil in them (as they sometimes just have grease from the factory) set-up your diffs with oil in them which will help your overall handling on the track. otherwise check out online forums for that truck if you can find any and see what other people are doing or saying about/with that truck.
www.truggyracers.com used to be a good forum, but i'm not sure it's still up..
too many toys; too little time..
put out what you want back....
