what a difference they made. very happy i did this. i now have my original power back. i can put truck in od from 45 and up and it will pull almost all hills without shifting down just like it used to. best 2000 i ever spent. before gears i couldnt pull 50mph flats in od it would shift down.

 

How do you like those bilstein shocks? I was thinking about getting some for my psd.

 

Much difference in mileage?
Nut

 

never had different shocks so i dont know on that one. will check mileage soon.

 

What did your RPM's end up being?

 

Kwik it looked like around 2100-2200 at 70mph. i was trying to adjust the speedo this morning setting it to my gps but i will get more accurate info. for set my computer for the 430 gears and 37 tires. and im fine tuning the speedo with my superlift tru-speed.

 

hmm, my dually with stock rears is running 2100-2200 rpm at 63 mph. Id be interested in seeing what yours is running at with the speedo calibrated for the tires, with that big of rear ends in it.

 

according to my gps i have the speedo within about 1/2 mph. its pretty close right now. with my 373 gears i was about 1700-1750 at 70mph. sure feels alot better now

 

That new gearing sounds perfect.

 

Hey MTman what was the gear ratio you took out?

 

Post 8 refers to 3.73s.....

 

yep 3.73s are what i removed

 

Awesome. I knew the 4.30's were going to be the best match for your needs. Glad you're happy with them.

 

thanks cookie im very happy

 

Where did you get your 4.30s from? Did you install them or a local 4x4 shop or the dealer? How much was the total price for front and rear including labor?
