right now ive got the stock 2.73 and it sucks, obviously. so anything is an imporvment. i dont need anything too big because im not towing anything. im lowering the truck soon (18s and lower profile tires)and its only going to be a daily driver to school.

whats the best place to buy a complete set?

 

OK, so now you may have a different story. If you are lowering the truck, you will probably be going to smaller tires. That tire diameter is very important in this decision.

 

PUT 3:73!!! GIVES YOU GREAT PERFORMANCE AND WORKS GREAT ON THE HIGHWAY AND ITS NOT BAD ON GAS.....4:10 ARE FOR 1/4 MILE RUNS AND BAD ON GAS AND NOT GOOD ON DA HIGHWAY. I WENT FROM 3:43 TO 3:73 AND LOVE IT

 

But again it depends on the tire size you plan to run. So what tire size?

 

well i was looking at going with 32" tires originally but thats a big jump from stock so i might go with 30-30.5" what would be a good option for me?

 

since you have an overdrive, I would go 3.73 for power, 4.10 for a ton of power ( but will hurt milage). No lower that 3.42 if you want to have decentpower. 3.23-3.42 will be a good all around for you. If it were me, I would go 3.42 I was worried about milage, 3.73 if not.

 

well with the larger tires and switching to the 3.73s think id get about the same mileage as now? i mean im not THAT worried about mileage but it would be nice wouldnt it.

 

You will probably get better mileage, since you will be back in your power band instead of below it.

 

i found a 12-bolt with posi and 3.08's for $250. good buy or not?

 

sounds like a good deal to me. is it the entire axle casing and all?
