I had the pleasure I going to Augusta and test driving/ meeting w/ the engineers on the 110, 4x20 and the 5x25.
I wanted the factory armor kit and was told by the engineers they only sold 70+- for all the 4x10's from the factory so it was not being offered on the new 4X20's. That was March of 2005.
The armor kit we talked about was only protection for the rams on the loaders- no belly pans??
They suggested I talk w/GR Manufacturing in AL, I did and they do not have a armor kit so I had a full length belly pan made. Great coverage except for the hyro ram used for the steering. It even protects the filter under the right side tire.
I would post pictures but fail, if you want to see it send me a PM with your email address and I will try to send.
