IIRC correctly when I bought my S-60 five years ago a 9" from Strange was around $2250 without brakes. My S-60 directly from Strange was $1845 without brakes.

I went through this same argument with myself when switching from an 8 3/4.

I ended up with a strange housing, Pro HD center section, 35 splines axles and the strange rear brakes. I felt the 9" is more user friendly for what I wanted to accomplish. With the aluminum center and sheetmetal housing it is probably around 25-30 lbs lighter than an S-60.

Here us what I paid.

Strange sheetmetal housing with ends welded on - $525.00
Strange Pro HD center section with a spool, 4.10 gear, and billet yoke - $1245.00
Strange axles with bearings and 5/8 studs - $515.00
Strange rear Brake kit- $580.00

Total - $2865.00

I was quoted somewhere around $2000 for an S-60 with no brakes and a spool.

So all in all I feel like the price point on both of them is right around the same if you compare apples to apples.


Here you go, right here. These are legit prices if you do NOTHING yourself, other than pick up the phone, for a rear that would likely be good to the 8 sec range. He also included the price of what the Dana was going to cost still needing brakes. And it appears, that the costs will be within a couple hundred bucks or less. But I feel certain someone will be along shortly to point out that they built one for 6 dollars and change.

But as always..........the bottom line here is choose what you WANT and what works for YOU. In the end, me nor anybody else here should care what rear you decide to use, after all it's your car. My only point is in trying to point out what some REAL WORLD pros and cons are, without all the "hype" that always appears in these type threads. So if you are a Mopar parts or die kinda guy............that's fine, follow that path, but why condemn the ones who choose NOT to follow that thinking.

Brad asked for simple pros/cons.............not a philosophical debate. Guys always feel the need to defend their choice, instead of simply answering the question

For what its worth when i ordered the rear I asked many questions about longevity and the strength in both the 9" and the s-60. I was told that while the S-60 is a very good rear, it is hindered by the factory style cast pinion support, whereas the 9" with it's removable center section is available to all types of improvements.

Also because of the pinion sitting deeper in the 9" pretty much both Strange and Moser assured me that there was no comparison of strength when comparing an aftermarket case 9" to a Dana.

really what it cam down to for me is that I don't like working on Dana's at all. The 9" is basically just like the 8 3/4 in overall design and since I was familiar with that and like the way you can set the center section up and the put it in the car it was favorable for what I wanted.

Either way unless you have a way to shorten the housing on the cheap I think you will spend in the ballpark of what a new unit costs.

When I made the swap from 8 3/4" to 9" I found a junkyard 9" from a Lincoln Versailles for $50.I scrapped the brakes,axles,and complete carrier,the only part I used was the housing.I bought the 33 spline Moser axle spool deal for $550 and got a factory "N" nodular housing from a friend for $150. I got the Summit brand 4.56 gears for somewhere around $160,Jeg's had the best deal on a setup kit with a "Daytona" pinion support for around $280.For brakes I used a "stock car" type deal with weld-on caliper brackets,GM calipers and Jeep rotors with Russell lines for about $160 in the whole brake system.Final touch was a used Moser billet yoke for $50. I did all the welding and setup myself but if I were to charge someone to do this I wouldn't do it for less than $400.
So we have an $1800 9" that will take the beating of a 3500# stick shift 11 second bracket car. I didn't backbrace the housing because the Lincoln housing is quite beefy when compared to a standard pass car housing.
So I'm pitted next to my buddy with 67 Camaro running low tens with a Dana plucked from a 66 Plymouth and he wants to trade his Dana for my 9" even up Both 4.56 gears and spools,but the Dana still had drums on it.So I said "what the hell lets do it" That was about 10 years ago and I know the housing is bent because the axles don't go in as easy as they once did
So all I had to do was bolt the Dana in and bleed the brakes but I had to pretty much build the 9" from mostly aftermarket parts
I like them both but for ease of service the 9" gets the nod

What is considered to be enough HP to bend the Dana 60 ? Is this equally true for narrowed rears with the ladder bar brackets welded to the center section?
Hard for me to imagine bending this rear with the short and heavy wall truck tubes.

Your heavy walls tubes are a help... but the distance
from the ladder bar or 4 link mounts to the end is the
important part.. thats the reason I back brace right
out to the outer bearings

Moser site is only showing a 9 rear with chromoly tubes with the floating ends.
Is this the one?
If so is seems a little over kill or I'm I wrong?
Not trying to

No they make one with normal ends.

Never fails, the comparisons ALWAYS go to this kind of ridiculous crap, instead of keeping it relevant to the topic at hand. Lets never let facts get in the way of a good loyalty questioning..........LOL!!!



I did ask in my first post to keep it to the facts... but I can't control the weather, either.

One of the problems w/ coming up w/ an apples-to-apples comparison is there are so many options for 9" stuff that I don't know what's adequate (or comparable to an S-60) for the application to price it out.

Also, I really have to approach this as buying a new assembly from a vendor, rather than piecing something together on my own. My time constraints just to get an engine back together, etc., are tight enough as it is.






Trying to figure out what I need with the ford 9

1 a nodular iron centre section.
2 Pinion support.
3 Back braced housing.
I'm I missing anything?


I have a strange iron nodular housing with big pinion support, Lenco Billet locker 4.10 gears brand new. probably one of the best street/strip set ups around. the Billet locker is over $800 bucks by it's self. I will make you a heck of a deal and maybe work out a trade for you rockers

This topic is amusing. Similar to the last post on this I am waiting for someone with experience to quote a price on a 9" or 9.5" rear with the back brace, axles, yoke, etc ready to install with a carrier that will live in a high 9-low 10 door car and still be okay on the street. When I talked to Dr. Diff about this he was adamant that the Dana 60 was a better deal due to the stronger/larger power lock internals. If I could find a reputable place to quote me on a Ford 9" it would be a consideration. Instead the guy with the good reputation is telling me different. And don't just tell me to "call a competent fab shop" because I'm not playing that game. That is how I ended up with all of the other junk that doesn't work right.


Call Currie or Moser and see what price they quote you The last comparision price I saw a long time ago in a magazine about this same debate was a Dana 60 was betwen $300.00 to $1200.00 less than the same equipted Ford nine inch type rear end, that was with no Ford parts in it, all aftermarket H.D or race parts The lastest quote I have heard of for a all out race chrome moly housing fully prep with all the mounts for a drag car was $2500.00 It ended up cracking and leaking after several races from tire shake, they had to have it welded up to repair it As far as all the race cars using nine inch type rear ends that sort of displaces the old adage about not being able to fol all the people all the time, huh I seem to remember the early Olds and Pontiac rear ends being the hot set up for drag rear ends back in the 1960 and early 1970s, before the Chrismans made up all the media hype about the Ford nine inch being so good How about we put this post to bed now I know that won't happen, will it


Cab that's the biggest bunch of bull I have ever read on one of these debates.

Yeah, it's been covered differently on other posts over time, but I'd like to hear specifically WHY people prefer the Dana 60 (or modern replacement) vs. the current Ford-type 9" differential for a stout street/strip application.

Just checked out Strange's web site and they do offer both as bolt-in assemblies for an E-body, but I didn't dig deep enough to start coming up w/ $$$ differences, or whether things like my current 8.75" drum brakes can be swapped directly to a 9" assembly, etc.

I'm not prejudiced against either, since I like the drop-out centersection design of my 8.75", and my ol' A12 Road Runner had the factory-installed Dana 60 backing up its 4-speed. I'm looking for legit stuff, not a bunch of subjective "You wouldn't put a FORD rear under your MOPAR, would ya'?" type comments, or whatever comparable would apply to a Dana.

So, please tell me the pros & cons of each. At some point I know The MoPig is going to need something better than my 8.75", so I might as well start asking now.




Brad FWIW I bought a S60 from Cass (Dr.Diff)last year great guy and great service.
It was about $600 cheaper then the 9inch at the time.
I think it will be all I need.

The focus of this thread started as a comparison between a Dana 60 and 9" for a high torque STREET/STRIP application.

These are actual prices of comparable rearends that I will sell any day:

New Strange-60 Dana 60 assy, forged steel 1350 yoke, choice of ratio, Strange-Trac differential and 35 spline axles complete with leaf spring perches installed $2225

New Strange-9" nodular iron case, aluminum pinion support, forged steel 1350 yoke, choice of ratio, Strange-Trac differential, 35 spline axles, fab housing with short back brace and leaf spring perches installed $3175

The price difference is $950.

The weight difference between these 2 assemblies is negligible, with a slight edge to the 9".

The difference in efficiency between these 2 assemblies is negligible, with a slight edge to the Dana 60.

The size of the 9" differential is dictated by the presence of the third "pocket" bearing. Because of this, 9" differential internal parts are much smaller and weaker than the Dana 60 version. This is not a concern with a spool, but it gives the Dana 60 a big advantage for a heavy/torquey street/strip car with a traction differential.

That is a SPOOL equipped 9" third member built with imported parts.

Even though this thread concerns STREET/STRIP rears, for comparison purposes, I sell COMPLETE, US made, spool equipped bolt-in Strange-60 rearends for $1795

BTW, a BARE 9" Strange-Trac 9" differential runs $995

Whats wrong with the 35 spline Detroit Locker, which can be bought for $500. Why do you need the $1000 Strange unit? It's understood you are a Strange dealer and that's fine, but they are not the only game in town. As stated, a Locker can be bought for $500 complete. A Nodular "kit" with housing, support, billet yoke, bearings and assy kit is $495. That puts a center at less than $1000 and then add you choice of gears. A street gear would seem to put a ready to rock, Locker equipped center in the $1300 range. I found those prices with about 2 minutes of search time on google. I'm sure more diligent search might find it even cheaper
