I'm planning out my Dakota project right now, but this is my first Dodge as a project and my second Dodge ever. As such, I'm out of my comfort zone. I'm thinking about building up a Chevy 12 bolt with a C-clip eliminator kit to go in the back of my truck. Choosing it over a Ford 9 inch due to the 12 bolt is lighter and more efficient than the 9 inch while being just as strong. I tried looking into what Dodge makes, but there just isn't that much information out there on Dodge performance rear ends.

What I'd like to know is, does Dodge have a live axle with comparable strength to the Chevy 12 bolt?

 

out of all the dodge trucks ive owned i always had an 8 3/4 rear had one in my drag truck never broke. same truck killed a 9 inch ford (but that diff was out of a dirt track car possibly why it broke lol)

 

The Chrysler 9.25 is a pretty tough axle.

 

the 9.25 is a 1/2 ton axle, Chry 8.75 or Dana 60 are good and offer C clip elimination (pressed bearing)

 

Thanks. Still not finding much on the internet about them, although I kinda like the looks of that 8 3/4 rear. With the power I intend under the hood, I'm probably going to have to go aftermarket for the assembly. Does anyone know how efficient the 8 3/4 and 9 1/4 are compared to the Chevy 12 bolt? The Ford 9 inch is 2-3 less efficient than the 12 bolt, and I don't want to be wasting any engine power on overcoming gear angles in the rear.

 

i dont know efecient wise an 8 3/4 is ...i do know i had one in my 65 d100 behind a 40 over 440 with a racer brown ssh44 cam and ported heads and it held up for about 6 years and ran a 29 inch slick it was the smaller pinnion bearing model with 3.91 gears witch i beleave is the weaker of the 2 sises

 

I am going full float ford 9" myself, but I am overbuilding the truck.

The 8.75 and dana 60 are very similar to eachother and basically use the same outers. Only the .75 is front-load like a F9" and the 60 is rear-load.

A couple percent of loss is not really measurable in HP terms. You'll lose a whole lot more than 5% in the transmission unless you go with a manual.

 

OK, so is the Ford 9" and I believe the Chrysler 8.75 was used in 1/2 tons as well.

 

Actually the 9" IIRC is considered a 3/4 ton axle, but aftermarket housings like I'll be using can go all the way to 5/4 ton rating.

 

The 9" came in f150s and Broncos.
