Nope skids are the same, I swap mine out sometimes on accident. In all a revo is the best bang for your buck. I got about 6 gallons on a set of ends last time before replacing them, it just makes it sloppy, but I didnt notice a differnce in handleing. Ditch the Maxx and Get a real truck lol. Oh and the 2.5 is junk imho, and traxxas dosent even make it anymore, as far as a revo goes. The 2.5 chassie is fun to drive, I actually really liked my 2.5 chassie, and would weld the sucker back together if I could lol. A 2.5 with a 3.3 and a trinity pipe, I couldnt get the front end to stay on the ground lol.
