Hey guys, whats the most fuel efficient diff i can put in my 2wd 5.2? (alternately , most efficient tire sizes)

Thanks

 

Well what are you gonna use the truck for? The factory 3.55 with 235/75r15 would be alright. If you really wanted to push it 3.21 could work but it would be gutless and I wouldn't want to tow with it at that point.

 

Case of beer and some friends pushing it down hill. Or a non suv.

 

k, thanx guys!

Just tossin around some ideas in my head and wondering. Dunno how much towing i'll be doing, but its not gonna be a house or the space shuttle or anything like that for sure, so if i went with 3.21 i'm guessing i'll be alright?

Got the 2wd, so I guess i consider it more of a station wagon than an suv (plan on lowering it, after all) so more mpgs would be cool.

BUT would it be worth it?

 

Realistically...no. But to each their own.
