Technical The Allure of the Quick-Change Rear End.

Stock Car Products made their own QCs. I have one in my shop truck. They are similar to the Frankland, Winters and several others. The center section is 3 3/4" wide and they use a deep rear cover.

SCP also made differentials in the Tru-Track style. I've never seen a broken one.

 

^^^ Thanks for the information. Where are they made... if still in business?
The HAMB is great!!

 

Originally in Richmond, VA. The company has changed and now manufactures dry sump pumps. Located in Ca.

 

^^Thanks for the quick followup... guess I have a "collectible" quick change rearend!!
Are there any existing threads about SCP that you know of?
We all love good stories but at least we know the ending when we start... bummer but still glad to know!
Thanks again.

 

Thanks, I’ve seen the cable and handle that Speedway sells, but I’ve been unable to see a photo of a Halibrand 101 with any linkage or cable connected to it.

 

The Sprint car I used to drive had a lever that attach to the torque tube and that a detent and you just clicked it back and forth.

 

I went to a lot of trouble designing this spring ahead suspension so I could show off the quick change ]

 

Just curious, as I'm still learning.... how many of you with QCs actually change the gears before/after a roadtrip?

 

In the very first posting it lists a new Winters Q.C. is available - from who, and are there different widths, bolt patterns, and early Ford / Lincoln brakes?

 

Winters has traditional appearing axle tubes/bells that have the variety of big Ford ends.

There are adapters to use vintage axle tubes/bells, that can take early Ford, and possibly Lincoln brakes.

The bolt pattern is axle shaft dependent with single-float axles.

I believe that @GearheadsQCE might be able to shine some light on that. He's my connection for Winters stuff.

 

Some useful info about hubs, if you scored a Grand National setup:

There are full-float GN hubs that have the 5-on-4-3/4" pattern, rather than 5-on-5". A few models have 5/8" screw in studs. There are 5/8" to 1/2" stepped screw-in studs. That combination gets you into more common wheels and studs.

It is what I run on my quick change rear.

 

@gimpyshotrods ,

Thanx for the shout out!

@steve hackel ,
Yes, Winters has several brand new Quickchanges that fit our style cars and I am a dealer for them.

I'll send you a 'Conversation'.

 

Can anyone identify this thing? Looks like a Frankland center, but I don't have a clue what the bells are..

 

I've not seen that one before. A couple of other QC makers had bolt on tubes but they were different than that one.
Don't be surprised if they turn out to be Frankland. There were a lot of variants made.
Are there any part numbers etc. on the bells or tube adapters?

 

I've seen a lot of big QC rear ends (have 3 different brands myself), but not that one! It is sort of "Big n Ugly" . . . sort of like my ole' girlfriend . . . God I miss her! LOL

 

@GearheadsQCE - I believe the center is A frankland. But the side bells and tube bases have me confused. No ID anywhere on the outside.

@Bored&Stroked - lol @ "Big n Ugly"

 

When they are too blown up to run, ya just need to find a new use for them!!

 

Only time will tell.

 

Time moves faster in a Quickie . . .

 

Day light saving time-quick change!

 

I don't know where to start with pictures. I like the looks of this rear end I built in about the late 70's. I used 2 left side Frankland bells with a spacer in the right side. 2 Mustang left axles. I sold it to a street rodder for $1,900.00. I couldn't believe they would spend that much money on a rear end. I am looking for a pair of these side plates or either side if you have one.

 

The old days. 301 Halibrand with truck left bells. W ent to Austailia. Only had to ship it to Long Beach.

 

Custom built 201 steel Q C's. Highland, Bart, Frankland and some others used a 7/8" thick steel spacer plate [ Heavy and a lot of welding ] a spacer ring and a 1/4" plate to hold the spacer ring in. I eliminated all of that with my cast aluminum extension. K I S. Used Halibrand or Speedway Motors cover. Retired foundry owner cast up the extensions. I believe $7.00 per pound. One of my tenants bored and faced off the castings. No charge. I did the drilling and tapping. I made a fixture off a Halibrand 201 to install the front bearing retainer. No mill needed just a hole saw. Built 5. Three are in my cars. Sold 2. Can you spell CLEAN?

 

Now I have nine 301's. Two for the street. The rest are wide fives.

 

I used a Frankland 201 in the roadster I call " Potential contender A M B R " 50's type hot rod with a track nose.

 

Winters QC under the deuce Vicky

 

I've been thinking about doing something along that line, because I want the strength of a 9" for a high torq engine.....and I don't want the noise. I've been thinking about getting an old closed drive and seeing if it could be cut off in front and a plate welded to the front to accept a 9" pumpkin. Might have to space the bells out some,and then the alum housing slipped over like yours. Just thinkin............but I have some quickchange parts on a shelf.

 

Here’s my contribution, early-early Frankland fabricated quick change. Old southeastern dirt track stuff.

 

True
In addition to the obvious strength, ratio choices, and aftermarket support of the nine inch axle, I think it probably does not take any more time to change ratios in a 9-incher than to change ratios in a quick-change.
I'd be willing to bet changing ratios on my 9s is not much longer than changing ratios on a QC.
For a 9er, drop driveshaft, pull axles, drain oil, pull center section, install new and refill with oil, reassemble axles and brakes.
For a QC drain oil, remove cover, remove old gears, install new gears, reinstall cover, refill with oil.
