I just placed an order for a Posi unit and some 3.73:1 gears. I went with Auburn high performance series mainly because I have heard so many good things from it. I was thinking of going with the Auburn Pro series but I was told its only for hard core off roading or extreme horsepower applications. I think I got a very good deal. I only paid $515 for the posi unit, gears and installation kit. Oh shipping was free if your order exceeds $500. This shop that specializes in building engine, trans and rearends will intall everything for $190. So overall I think I got a pretty good deal. With my current setup, I ran my best time of 16.2(with traction problems). Now with the 3.73 and the posi unit, what do you all think I should be running?

 

is the install hard or have you done it before?
i would love to have a posi and 373s but dont know about installing it, etc. much less which posi to get.

btw where did you get it at?

 

yeah i'd like to know where you got it at. that sounds like a dang good price for a posi and 373 gears. can all you guys that already have the posi and gears tell me if i'm right on the pricing?

 

Actually, I got it at nationaldrivetrain.com

 

What 60' did you run and at what MPH did you finish the 16.2?

I really do not know my time for the 60ft or the mph at finish. At the time, I was only concerned about my 1/4m time. After I intall everything and go to the speedway, I will post my time.

 

Your 60' and MPH are the two factor which whould most change/effect ET with traction problems...having these numbers would give you a better idea truely how much you stand to benefit.

I had them install a detroit locker rearend. I traded my original chevy rearend I paid 450 for everything including a set of 4.10 gears.

 

Congrats! I just sold my 3.73 and factory locker since i just got some 4.56's and an Auburn Pro Series!!

Damn, i can spin the tires again <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

How are those 4.56 gears. I really like my 4.10s they seem to free the motor up and kill the bog down effect these trucks have. Does it zip through the gears pretty quick and how is highway driving 5 Grand on the tach or is it decent?
