I would also consider Eaton Posi if you're already going to have the rear dropped for the gears... just a thought.

 

I went with a Detroit TruTrac. The factory carrier is a known weak link.

 

+1 on the TruTrac. Going to some 4.10's myself.

 

Tire are 265/70r16

 

Theoretically, that's a 30.6" tire. I would probably go with 4.10s, no lower , unless you anticipate larger tires down the road. With OD and lockup, you'll still turn reasonable RPMs on the interstate. There are calculators online to tell you what it will be. BTW, gears are by FAR the single most important thing you're doing!

 

BTW HEADHUNTER92 look at my info about those OBX headers on page 1. You should buy them you can't beat them for the price.

 

Jrmchevyman.......i most certainly will thank you for the information definatley keep that in mind. Hey folks what gonna happen to the truck when i put the gears in until i get it tunes besides increase in rpm at operating speeds and the speedo be off until that gets corrected?

 

It will screw up all the shifts. Your speedo being off will mess them up. It'll have to be tuned at the same time.

 

How would a muffler from the deisel class sound.(like the edelbrock) obx style headers with cats,duel tail pipes,one behind each tire? Think i would be loud dont wanna say huh while i talk on the cell or have to turn the radio damn near all the way up just to hear it.

 

I have a Banks Monster exhaust catback system along with the ebay headers and y-pipe and its just right for me. I had a magnaflow oval case with single 3" pipe dumped behind the rear axle and it was loud, but it gets old after a while. Stick with the 3" single systems for maximum torque. Banks, Borla, Corsa, Magnaflow are some of the best brands or have a custom system done using mandrel bends. Oh and keep in mind those ebay headers, have no converters! ie smell, air quality, dirty looks
