It's a Mopar. Put a Dana under it.




Since when is a Dana a Mopar part? Both my Dana's came out of 1 ton Ford trucks. If I was starting from scratch I would put a 9" under the car to save weight.

And that just about sums it up. Monte's post was right on as well.

You can front brace a Dana, but the shorter it gets the stronger it gets which you have to do for bigger slicks(more hooking ability). I guess the other item is how far out the bars or springs are at the fulcrum point, most are buildin them now on the inside of the tubs close to tires. The only Dana I saw bent was a heavy 4 speed car that wasn't welded around tubes to housing. But I agree the 9 inch is preferred because of the gear avaliblity and easy to change at the track. If your are running some type of class that's fine but we are just bracket racers in the end so why, trick of the week? Put a dana in it then check it every ten years and worry about all the other stuff that matters. This is my opinion and does not reflect the managements.

You can spin the Mopar part bs to no end. The 9" rears I see have no Ford parts. If you choose to run a torqueflite or 833 for the same reason you would probable want to run a dana.

If you are building a serious et car choose a 9. Unless you desire less drag and a higher pinion.

The guys who usually ask the question as to what they should run actually should choose the Dana 60. 9-11 second full body cars with a well prepped Dana will never hurt it. Some rare cases where the guy wants to slam the car on the ground with big wheels and tires should choose the 9 to keep the driveshaft out of the tunnel.

Call it a pet peeve just get tired of the everybody should run a 9" just because someone else said so.


Career best 8.02 @ 169 at 3050# and 10" tires small block power.

I agree ,
But,, I'm not a fan of running 9" Ford's over the 8 3/4 wr have ran deep in the 9 s with basic stock gears in an 83/4 with no issue's. But some.have I'm sure it has to do with leaving at such high rpm s something going to break!
A Dana maybe heavier but it is.not robbing as.much hp as those.of the 9" and 8 3/4 do so even tho you change to it most cars do not lose et. Some may gain .




Several guys have got by running an 8 3/4, I didn't. Mine broke the second time my 408 hooked up. It had maybe 30 7.30 1/8 mile passes and 1000 street miles behind my 340. The Dana is worth the $$ for the piece of mind.




No disrespect but power didn`t break it cos I`m pretty sure I`m making more than you and mine`s fine so far w/stock caps BUT set up properly.............

Yes.. like Monty said.. weight creates more friction/load
on the tires and that creates more deflection on the
pinion to try and flex out of the ring gear

Thumper, great car but I think you'rs is flexing to absorb the shock load kinda like falling on a bed or the floor, whitch one more likely to break something?

I know you're making way more power than I am. It made no noise on the highway, no vibration and the wear pattern was good. Maybe I just got a bad set of gears. To ME it was not worth taking the chance again, so I fixed and sold it. The Dana is not much heavier and I have peace of mind now. I know a Dana is not a fix all end all and may not be right for everyone, but it's right for me now.

BTW Thumper, please explain "set up properly".

still has nothing to with set up, we ran for over a year with a 9" slick and had 0 problems. put an 11.5 slick on it and boom first pass and only running a little faster than him. there is a lot more to it than set up. you are not the only one on the planet that can set up a rear. put them slicks on and hook for us

Maybe but it`s back braced and I did twist one and roll the perches before they were fully welded on. Justin, again we hear all of these stories of broken 8 3/4`s in slower cars then myself and other way faster guys make em live...........

It runs 6.50's-70's with the 408, 1.38 60' at 3260#. Not up to your standards I know, but it's just a pump gas small block.

We've had a Dana in some fairly powerful and heavy cars without issue.

Starting from scratch, I wouldn't waste the money on a 9in housing, but instead go right to a fabricated deal. The stock 9in is no big deal. It only becomes the "rear of choice" when it's heavily supported aftermarket is exploited and in my opinion, that includes a huge selection of housings.

You can brace a 9in housing, both inside and out, but if you are starting with nothing.....why bother??? Just get one of the good 8 million fabricated housings and fill it with the good stuff.

An S-60 is less expensive than a really good 9in and will last just fine in numerous combinations and it's slightly more efficient albeit somewhat heavier depending on the set-up.

Why dick around with either and run the 70, its a 10.5" ring gear and has the same outer dimensions as a 60. I found one that has 1/2" thick 3.5" diameter tubes that weighed 58# when cut down to size. The 9" pinion is smaller than a dana 44, it only has a 3rd bearing to reduce flex. Nines are just puny compared to a real axle..Tim

I'd say my S-60 is the same way. Probably nothing Dana but the design and Strange even changed that by adding adjusters on the sides.
