i have a 99 1500 2wd i am looking to do a gear change. i am looking for more acceleration. i have 3.55 in it know. i have a shuperchip tunner, headers and cat back dual exaust. what would you guy recommend going to.

 

Probably 4.10s but I'm not a gearing expert. What size of tires do you have?

 

i have 275/75/16 i just dont wount to run high rpm on the freeway

 

4.10 or if you really want a new beast 4.56 the 10s are a little better on gas if you do a lot of highway driving the 56s puts all power to the ground and there are even a few guy that have really gone big with 4.88s but that's now a highway friendly gear

 

I have 33x12.50s and I'm still running stock 3.55s. Hopefully after it comes back from the shop with everything I'm doing to it, it'll run like a champ. I'll probably change my gears to 4.10s in Spring anyway.

 

do you know what rpm you would run at 70mph with 4.56

 

Depends entirely on tire size

 

This is the best gear/tire ratio change calculator...ever.

All the others are posers or wannabes.
