"05 4WD Dbl Cab Rear end?

[jdmull]

Just put new 285/75/16's on my baby. Interested in the possability of changing rear end to get same perfomance(mpg, and all that good stuff) as stock. Any suggestions? Curently have stock Ltd slip diff. that I believe to be a 3.55. Thanks for any input.

You have the 4.10 on your DCAB. 4.30s would prob be the perfect match, but for that little of a change is it really worth it, and you might as well do 4.56s to make it cost effective. Then of course you are probably going to get worse mileage wtih the added RPMs at cruise speed, but the power will be nice

Actually the 05 DC's are back to 3.91's. I guess they don't need the 4.10's with the closer ratio'd 5spd auto.
