where do i buy them? is there anything else i need to get with it? or is it just a straight up swap of the gear and nothing else?

 

www.moparpartsamerica.com

 

www.ringpinion.com has much better prices then Mopar. You can just swap the gears over, just replace the seals and crush sleeve if your axle has one. You can get a full bearing kit that has everything but unneeded if yours is in good shape.

 

thx for the links guys, just looking for some more input, the only mods im going to prob be doing to my truck are the fastman/(or)hipotek tb, tuner, and exhaust. just unsure of which gear to get with that setup. i remember someone saying at a certain point your mpg will start to suffer as the gear size goes up. right now currently im looking at 3.92/4.10 gears. any input?

edit: also what brand should i be looking at for the gears? i see there is a few different manufacturers like us gear/yukon/usa standard/etc

 

if your 4x2 Id get the 4.10s
youll prolly lovem

 

So will your local gas station !

 

A guy reported a few months ago that he went to 4.10s and actually got 2mpg better with his city driving. On the highway, they probably arent the best option

 

Yeah, no joking around...you will loose about 3mpg on the highway..but it will be fun doing it!

 

Actually It really depends on tire size. They can be win win

 

so would 3.92 be the best option?
