Quick Change rears and '60s gassers...

I have a chance at a complete, ready to go original 4:11 Franklin quick change rear. Would this be acceptable for a early '60s g***er '55 Chevy? Car is powered by a bored/stroked Paxton supercharged 327. Hook it up on my leaf springs with some ladder bars... It has the wide Ford bolt pattern with discs. Also how are these on the street? Is it like a spool? Is there any way to get drums on it or would it be ok to just use the discs. The car has drums all around now and is a strict '61-63ish era rod. Thanks,

This was posted a while back, and the general opinion was that they aren't strong enough in a drag racing application.
I wondered the same thing for my '57.

It's not that they weren't used on this era race cars, but I can't recall seeing one under a tri-5 Chevy. They were usually seen under lighter cars, and especially light cars without big engines.

 

It will hold up fine if it never hooks. Under a car as heavy as that it will break if you grab traction. It may or may not be a spool you have no way of knowing without getting inside.

The ****er 60 was the main stay of the heavier cars with big grunt mills.

 

Thanks guys, guess I'll just stick with what I have. Its set up great now with a 4:33 P-Case rear and traction bars, but this Franklin just looked so bad*** that I started thinking. Plus that whole wide Ford pattern and brakes would get kinda funky too. Thanks again,

Check out the book G***er Wars by Larry Davis. There is more than a handfull of cars with QC rears.

As for the durability of a Frankland QC, you will NEVER break one if put together properly. These are the full size QCs you will see under your basic late model modified at the roundy round track. NOT the V-8 small '40 Ford lookin ones. The small QCs start spittin out parts with a hot small block and some traction.

Frankland and Winters style rears are a 10 inch ring gear, with big giant axles and guts. Nothing easily breakable in there.

If you are doing any street driving, ditch the spool for a gear style posi. (200 bucks on Ebay for a good one.)

Here is my pile.




Haven't broken it yet...

The "jackshaft" was the weak link in the Frankland. I believe that is the shaft that goes from the yoke through the bottom of the rear and carries the lower spur gear.

 

Hello:

Please ID which model of Franklin QC in the attached pic.

 

I have one of these QC rears for sale complete and cheap. $500 for the everything. This is the large Quick change if any one is interested.
