RE: center diff lock?
Wild doogie.. Abso-freakin-lutely!!!!! You have no Idea how bad I want to do something like that here in AZ!!!! I loaded a bucket up with rocks I had laying around an pulled it with my nemesis awhile back and it was no problem!!!! couldn't tell you how heavy it was for sure but damn it was fun!!!! So I went looking for other things to do and saw a few videos several months ago and realized I live in the desert nobody out here does this stuff!! I am so envious of you boys back east that have organized events of this nature. the whole purpose of these trucks is to beat on. And beat the snot out of my Nemi and she keeps coming back for more!!! I would love to see how yours does please keep me posted!! there are some other mod I would suggest you do to get the full power of the nx76 to the ground without breaking. I strongly believe you easily pull 200# with it setup right!! the first I suggest is to stablize the fuel pressure in the tank with my OFNA check valve mod.. PM me if you would like to know more about my mods!!!
Thank you for posting your website and letting us know you are here!!!
