Well, I thought I had everything covered for this gear instillation. Just have a couple more questions:

I've been told that the front axle on my 04 1500 4x4 is a chrysler 8.0. I also researched around a bit and found that thefront is a crysler C205F, which im showing to be a 8.25.

I need to know for sure which one I haveso I can order my instillation kit.

 

It should be an 8.25. I can get you exact info if you PM me tha last 8 digits of your vin....

 

The 205 stands for millimeters. 205mm = 8.070866142 inches. My sticker in the glove says 205MM.

You have an 8" ring gear, just like mine.

Go to ring-pinion.com and look up your truck.

 

The axle housing is considered an 8.25 and the ring gear is an 8.00 diameter

 

Im at work and cant get the vinright now.

Just so I'm clear, the gears I ordered are 8.0in.

The install kit I need will be for the 8.25in?

 

You DO NOT want to spec. an 8.25" ANYTHING!!! A Chrysler 8.25" is a REAR DIFF from older Chrysler products and can be recognized by the oval 10 bolt rear cover & 27 or 29 splines. This is most commonly found on Diplomats, Darts, New Yorkers, Fifth Avenues from the 70s & 80s, although it did find it's way into some 1/2 ton vans, trucks and Dakotas.

You want the 8.0" Chrysler which is for current IFS front diffswhich can be recognized by a distinct 10 bolt cover with eight sides and26 splines. Anything you order for your front end should be specifically for the 8.0 IFS differential... Any install kits I have ever seen are designated as C8.0-IFS...

 

Not to worry too much. There is only 1 gear set and install kit available for 1/2 04 Dodge truck front diffs. 8" Chrysler or 9.25" Dana. The install kits are the same.
