I have a 4.7 so i added 4.56 gears to compensate.....now i have no problem with hills!

 

Mileage looks ok, maybe just a tune-up.

Good luck...

 

Dunno, but I was up at KRC Performance just shootin' the chit one day, talking cam and custom tune and whatnot and Marty said "you really need the tranny tunes that your SC gives you with about 7k pounds" and I was like, "no way this thing is 1200# heavier than stock"...

Got my curiosity up, so I went to the county landfill and weighed it on the scales and sure enough, with my toolbox loaded up and my fat a$$ (about 280 lbs) inside I was just over 7k pounds!

Now I don't know which is heavier, a SFA or a ISA with a full box sub-frame? Unlike most suspension lifts which have a single or dual crossmember, the Rancho kit has a full boxed sub-frame. Big strength advantage, but also big time weight adder...

 

Are you ever gonna use that cam of yours Hammer?

Maybe something in a recall? I was looking for things about my truck, and I came across this link. One of the recalls had to do with improved speed up hills and in reverse.....or check here
