You'll also have to get custom axle shafts.
The rear is the easy part, but while I'm at it I am also considering replacing the 9 1/4 with a Dana 60. Any idea of the value of a used 9 1/4 with 3.92's and a sure grip?

Why would you want to go to a 5x4.5 rather than something more common than that?
5 x 4.5 is the standard Mopar car pattern as well as Ford and AMC. What I really want to run is a set of Autodrags but they don't make them in 6 x 4.5 or else I'd be all set.

Why a Dana 60? Your 9.25 should hold up to whatever you can throw at it, unless it was 1000rwhp or 40" tires. I assume you're planning on tearing some stuff up.

Got ya. They don't make them in something like a 5x5.5 bolt pattern? You can use a fullsize 9.25 to get a 5x5.5 pattern if they do. The you might be able to get something off of an '05 Dakota, or just use wheel adapters. I assume you'd be against using adapters for the front though.

Well, my truck is a stick and I'd like to put some sticky tires on it and not have to worry about breaking the back end at the track. As it is now I leave the line like I'm pulling away from a light running with 1.9 to 2.0 sixty foot times while running high 12's, low 13's in the 1/4.

I'll have to research the 5 on 5.5, is that what is on the '05's? That would make things easier, I'm sure.

Are there a set of hubs with 5 on 4 1/2 bolt circle that will fit the front spindles of a 98 Dakota or am I going to have to custom make something?
No Dana 60 ever came with a 5 on 4.5" bolt pattern.

I've a list of 6300 BOM's from Dana, trust me on this.
5 on 5.5" or 6 on 5.5" or 8 on 6.5" and were not talking the new metric...

Why the hell do you want to run a heavy ass dana 60 for a race truck. There are PLENTY of axles that will hold up to whatever you dish out and save you a ( literally) ton of weight. Dana 60s are HUGE. I had on ein my crew cab dually chevy and that thing was huge X large. Besides you cant run really low profiles because of the centersection.
You dont want a dana 60 bro. Leave that to the 4x4 off road crowd.
personally I would go have 2 rims custom made for the dakota bolt pattern ( seems liek the easiest and really the cheapest way to do it. youll still be $$ ahead even if the rims cost you 500$ for the set of 2. I know some companies will sell you Blank rims ( that they havent drilled) you can take it to a machine shop and have them drilled to your hub and bolt pattern but I bet if you call on eof their sales guys you can probably sweet talk them into doing it or see if they willsell you a set of blank rims in the style you want

It would be a lot easier to grab a set of axles out of a ram with a 9.25 and have them machined to the correct length for the Dakota. I see no point to running a dana 60 and dealing with the speed sensorand buying a new driveshaft (I would assume the stock driveshaft wont be the right length?).
I cant think of a single truck (drag racing oriented truck) that has swapped out the 9.25 for anything else, and that includes the guys cutting 1.5's and better 60'.

I thought the rear width was the same in dakotas and rams??? I went out and measured the axle WMS TO WMS and it was 65" or close to that... HMMMM

I'm glad this topic came up again. I've been trying to find out the same info for almost a year. I planned on doing the conversion last fall but got sidetracked with the 408 buildup and install.

For starters, I found the rear axles are 31 spline, but I don't know the length or the pitch angle. I figured the heck with it, I'm going to have axles fabbed up if I can find the correct info.

The front is a different animal entirely. I don't even know where to begin with that, other than to start looking at Grand Cherokees to see if any parts can interchange, but then I still don't have the bolt pattern I need.

This is irritating as hell. I cant even find a part number for the axle shafts. I want to run a Solid Axle in the front eventually and would like to save the rear axle if I can It may be just as simple as getting ram axles and having them shortened and resplined. few hundred bucks maybe???
