stock it cannot climb very well at all but with just a few easy mods it climbs like you wouldn't believe. what you have to do is lock the diffs, flip the axles, switch the tires side to side so the tread is backwards and extend the links and drive shafts. It is very easy and strait forward. I just got mine and I've done all these mods except extend the wb but I'll be doing that this weekend. Good luck with yours.
