This past weekend I installed the Eaton Posi I purchased from Randys Ring & Pinnion (good guys to deal with), this little upgrade makes the truck run totally different, no more one wheel peel out on wet grass, and just the way it puts power too the wheels is a great improvement!

I recomend this upgrade for sure!

 

Cool - any impact on fuel economy? How much did it run you??

 

about $600 and a couple new carrier bearings, and good to go! not sure about fuel economy? not too worried about that with this update. just glad it doesnt allways spin out on one wheel.

 

How hard was it to install?

 

What lube did you use? I used royal purple 75/140 syn in mine, but the install notes said to use 80w90 dino. I get some chattering. I figured the lube was more a function of the gears/bearings than the LS, but I didn't research it much.
