If you want a copy of "Lower Forty", give Burnsville Off Road a call, they did a lot of the work on it.

 

That's an awesome rig.

 

The lower fourty is bad*** I would love to have one. I wish Jeep would produce a wider selection of more capable vehicles like they use to...now all they have for the most part is the Wrangler. Also, not trying to hijack, but what ever happened to this idea?

 

They changed it to this if I'm not mistaken. I read about it in "JP Magazine".

 

That lower forty is awesome but I would much rather have the j8
