As for mods and such. It is pretty much stock. I just keep replacing the parts I break. Everything for twisted CV axles, to ripping off my rear axle on a trail, I should not of been on. lol. On one trip out it caught fire in the engine compartment. I wad it rewired and running in less that a day. I finally got around to to putting 5.29 gears in the rear axle, but I think it was cut wrong from the factory. The pinion wont seat all the way down. Just need to get a hold of the manufacture. That is all I can think of for the moment. As soon as I figure out this site, I'll upload pics starting with the day I bought it, to where it is now.
