How wide is your rearend??

I was wanting to know what some of you guys with fenderless Model A's are running for width. I've got a pu and it won't be running fenders. Plan on using some sort of ladder bar and a leaf spring behind the axle.

A guy at work has a bunch of 9" rears and will sell me one cheap. I don't have a frame yet , just trying to get whatever parts I need as I come across 'em.

Thanks

Josh

 

Never owned a Model A.........


But most Model A guys look for the Maverick 8 incher from a V8 car......or a few 6 cylinder cars that came with the 5 lug wheels ( 250/6 cylinders). They are 56 inches ........measured like this........



A 57 - 59 Ford is 58 inches. That's ONLY 1 inch per side so they work great in a fenderless car. Wheel offset is also a factor.........

Here's a site with Ford rear end widths listed.

I measured mine and its 25" across both cheeks.

~sorry couldn't resist.

 

Agreed, 56" or 57". Ford 9" is super easy to cut down, ***uming you have someone to respline the axles for ya.

 

I went with 56" in my A roadster, a cut down van axle with the 5 on 5.5" pattern.

 

Too wide for my T Coupe. Perhaps if I lose some weight............

 

I don't know if this one would work for your application. I have it listed in the Cl***ifieds....

Nine inch Ford rear end made by Speedway Engineering, http://www.1speedway.com/Floater_Rear_Ends.htm#ssfloat . Has "floater" hubs allowing for easy change of the center section to another gear ratio by simply pulling the axles. The measurement is 51 inches from axle shaft flange to the opposite flange (as shown above). Also included is a Detroit "locker" and one or both gear center sections...a 4:11 or a 4:56. $1000. buys it all!

The housing bracketry is for a truck-arm type of suspension as this was a spare rear end for a Nascar Goody's Dash sedan.

I used a 9 inch out of a ford pickup. It had the 5x5 1/2 and I cut the housing down to 56 inches, wheel mounting surface to wheel mounting surface. I had new axles made from Moser, which was the expensive part of the deal, but my originals were the tapered kind which I couldn't cut and respline.

 

Very rarely can you find a rearend that will look good under a car by just getting one your buddy or some magazine recommends. The way to make your car look good and perform well is to narrow a rearend taking into account the wheel and tire combination you are going to run and the overall look of the car. With the availability of axle shortening services and rearend components it makes little sense to shortchange yourself on a component that contributes so much to the overall look of your car.

Good points Frank.

Thanks everyone for the measurements.

so how wide are stock T & A rears i have a coupe of org but am prob going with a 60 Imp rear as i have car & may use susp & rear on model A tub project but cant find a listing of what the A was for width factory ?

 

Heh heh....

 

arg morn Rocky that pic is just scary ..................

 

Best I can measure on a stock '30 still in the car with wheels on is a hair under 58" WMS-WMS.

 

I have an early Bronco 9" rear end ( 66-77). It measures 58" wheel mounting surface to wheel mounting surface.This is in a fenderless '30 model A roadster with 10" tires on 8" rims with 5 1/4" back space. This works well IMHO as I don't like the tires sticking out too far nor in too far. If you're going to run reversed wheels you may want to go with 56". 56-58" is a good range for this type of car.

60 and 1/2. Model A Sedans have to be a bit wider than coupes cause of the goofy wheelwells...

-Abone.
