Quick Change

I'm not very familiar with the quick change rearends as far as how they exactly work. So far, it seems that they are limited to 4.86 and 4.11 ring and pinion gears. I know that there are two gears that it looks like are changed out to change the final ratio, but i don't know if this will only raise the ratio or if it can both raise and lower it. My problem though is that i'm looking to put one of these in my s-10 that'll be mostly for show and driving on the street, then i'll need something around a 3.08 or 3.55 ratio. However, i intend to race it from time to time and the engine will be putting out gobs of torque. is this kind of rearend strong enough to handle this kind of stress like a 9-inch is? Or am i just better off trying to find SOME manual overdrive trans to go in it with a 3.80 or near there gear?

The strength depends on the model of Quick Change rear you have. None of the old ones were designed for big horsepower large tire drag race starts as they are based on the old Ford axles and center parts. Check Speedway Motors catalog and you can get a general idea of ratios available.

I'm positive quick changes have tons of different gearing choices, whether they go as low as 3:08 I'm not sure. Remeber Circle track, some road course, etc, racers use these. I owned a nice one for my circle track car, but had to sell it, so I never did look into the gearing possibilities too much. As for the lower gears there have got to be gears out there for damn near anything you would want.

Also the quick change of today will handle quite a bit of power, the two names I've looked into are Winters http://www.howeracing.com/DriveTrain...ds-Winters.htm and Franklin. From what I have heard they are both good, and I'm sure there are more names out there, these two just seem a bit more prominent in racing (circle track anyways )


Let me know what you find out.

I'm lookin at putting a Quick Change into my kid'd semi-stock 1940 Ford. From what I've heard, the old Halibrand-sytle cases liked to break at the pinion end support, they called it the "factory supplied crack". The newer cases have been supposedly reinforced in that area. If you pick a middle gear set like a 4.56, you can say get a set of 1.25 to 1 quick change gears and then flip them from 3.60 on the low side to 5.70 of the high side. If you cannot find a mid range ring/pinion set, just get a couple of different quick change ratios. They make about 50 different sets which cost around $40 a set.

QC rear ends

The last time I looked there were close to 60 different bull gear setups for QC rear ends, and you either raise or lower the ratio, by switching those gears around. For instance if you install the bull gears one way, you may have a 5.50 final, but if you reverse the gears, in other words put the formerly drive gear on the pinion and the former driven gear on the Jack shaft, you will then have a final gear ratio of 3.07 with a 4.11:1 ring and pinion gear ratio.
Winters and Frankland or Franklin as we are apt to pronounce it, use the same bull gears, and a lot of other parts interchange as well. Both also use the same ring and pinion gears, whether 4.11 or 4.86.
Bull gears come in matched sets, so you cannot mix and match bull gears from different sets, even if they are of the same ratio.
Well if they were of the same ratio, you could mix them but they wont wear very long, as they are precision made as a set.
