I am going to start by saying I am a bit new to doing engine mods. Ive been reading up, and it looks like 456 gears are the way to go. Got it. Which is the brand to get? And what is this nonsense about 8.25", 9", or 10"? Can someone tell me exactly what I need to get?

Quicker acceleration.(win) Less strain on our not so strong trans.(win) More power for towing.(win) Faster down the track.(win) Better in town gas mileage.(win)

I would say it's a win, win, win win, win situation.


PS. Get a Sonnex Line Pressure Booster for your trans. It will make it last longer.

FYI... if you do the gears your pumpkin might need to be grinded on the inside for them to fit,i had to do it to my truck..if i am not mistaken i believe the 06's and some 07's have that problem..also if your truck is a 4x4 you need to do the front also.it's a mod you will be happy with.
