Where to find Ford 9"?

[mattausten23]

I want a better rear end for my 67 camaro so that I can build my 3 link! I know I can get 12 bolts all day from the junk yard but I see people running Ford 9s. I was just wondering why are Ford 9in rears used more? Are they a lot better? Also would it even be a good idea to pull one from the junk yard and re build myself to keep the $$$ down? Thanks for the help!

Maybe truck 12 bolts. And they suck.

From what I've seen a used 9" is always cheaper then a passenger car 12 bolt. Since they made a bazzillion more 9" rears.

There are many reasons why the Ford 9" became so popular. One of them being that the center section can be changed out very easily with very lttle knowledge required. Guys who would run quarter mile once a month but use the car for a daily driver the rest of the time would just swap could swap out the center in a matter of minutes.

Both axles can be built very strong but I think that the 9" has much more versatility and can be easily built to withstand whatever hp you want to throw at it. It's kind of like the original small block Chevy where you could make it do whatever you wanted - depending on your checkbook!!!!

I think I'm going to go with a 9"... but would it be cheaper to get one from a junk yard and rebuild it, or just get one from moser?

Well, if you get one from a boneyard you have to do your homework first. First you would need to figure out what width you need flange to flange. If you are staying with stock wheel spacing, offset, tire size and rim width then you can measure your stock axle and try to find a 9" the same width but if you plan on changing anything you'll have to find one to your calculated width. Even if you pic one up to have it narrowed, talk with the shop that will narrow it for you first. They need the housing/axles to be at a certain length range in order to do the job correctly.

Next, the center section and axles. You need to consider what gear ratio you'll want, posi or not and so on. If you plan on running more than 300 hp, you will want to stay away from 28 spline axles. Finding the exact combo that you need can be tough.

Finally axle mounts. Fabricating the mounts yourself to fit you car can be a time consuming challange. I'm not sure but someone may sell an after market mounting bracket set for a 9".

All that being said, there is a huge advantage in ordering the complete set up from a supplier once you determine what your needs are. With the 9" being as popular as it is, there are quite a few suppliers that can set you up. The one I ordered for my Skylark will hopefully be here tomorrow!!

Good luck.

Thanks for the run down! Sounds like it will be pretty much the same price then? I'm a 19 year old college student so I'm trying to get the best bang for my buck because $ is tight! Good luck with your build! Thanks

More versatile - yes...the same price???....what's cheaper??? That answer very much depends on what you exactly need. Ordering a complete 9" axle set up is not cheap by any means. If you can find a boneyard 12 bolt with correct brackets that meets your needs, or just change the internals of your stock axle, it will be your cheapest route by far.

Let's get some specifics; What hp will you run? Will the wheel and tire combo that you will run require you to change your axle width from the stock width? Does the axle ratio need to change from stock? Do you need posi? Will the use be for the street or strip?

My car is a driver already but I kind of want to start building it for the future as my street/autocross so definitely limited slip(herd thats best for autox).. My dream would be to have about 500-600hp to the rear wheels from an LSX..want to run a 6 speed. I want the rear tires to be 18x12s not sure on the offset yet but I don't want to run a huge lip..these are my goals over time..I want to swap the rear get brakes and rear suspension done and put my car back on the road for a bit as well!

Im in the same boat. Im getting ready to order mine from DSE within the next two weeks

I hope others chime in here but I'm afraid you may be putting the cart before the horse. 18 x 12 means you will need to at least mini-tub the car. The order in which this should all be done is: Figure out which brake package you will go with as this can make a difference on wheel size and offset. Then buy the wheels and tires so you have them for mocking up. Next, tub the car and possibly the frame to give the clearance needed to fit the wheels with the desired ride height. Once that is completed, you can measure from wheel to wheel to come up with what rear end width you will need to make it all work without tire rub. Tubbing can also influence your suspension mounting points and configuration.

Bottom line in my opinion is, work with what you have until you plan on doing the whole rear of the car or you will likely end up pruchasing your rear axle twice. "A" has to come before "B" in order for "C" to be possible. The only other option that can really help you plan is to find a car like yours that has the set up that you desire and hopefully the guy will let you copy what he has. That can be a huge time saver. Not many have done Skylarks like mine so I spent countless hours measuring, ordering wheels & tires, measuring and ordering the rear axle. Even without tubbing it it takes a lot of planning to get it right. I am doing my LS six speed swap right now.

Many kuddos to you - in the "texting" generation yet getting into some real American iron!!!!
