It does have the 6mm Rear suspension mounts (the ones used on both front and rear) the Diffs are stock..never had any problems with them, Diff fluids are 5K front.. 20K..center..3K..rear. Motor has 12 tanks of fuel through it, the hubs have fresh bearings..This hellfire has not been abused, I also have the stock pipe, I also have the stock hubs and the wide set, i also have the full sway bar set. This Hellfire started out life as an RTR but as you can see it's basically an SS now..for $450 I'll toss in the brand new werks clutch ($100 clutch).
