Hello everyone,
Just wanted to let y'all know that a Quick Change rear axle is a great option for our trucks.
I'm not trying to solicit business, I just think there are a lot of guys that could use one to their advantage. I'm trying to retire
While most of my stuff is aimed at street rodders, I have installed several QCs in trucks. My current '86 Crew Cab has one in it and I can tell you that it solves a lot of problems that come up with wanting and needing different gear ratios for towing, milage, performance and strength.
A quick overview of the most common style may answer some questions you may have:
What are they used for?
The most likely candidates are from stock car racing.
How strong are they?
Jamie Frankland says that they fall between a Ford 9" and a Dana 60.
What gear ratios are available?
There are approximately 67 gear sets with final drive ratios varying between 2.19 and 9.14:1 generally by about 0.2 increments.
10 minute gear changes for about $100 (less if you buy used)
How available are rear ends and parts?
These are based on 1938 - 1952 Ford 3/4 ton axles. (also referred to as Timken rear ends)
Still used today and each and every part is available.
What about axles?
Most applicable to our use are:
1. Push in style, like Ford 9" passenger cars and trucks Big Ford Bearings and brakes or Torino pattern housing ends.
2. Full Floating with either 3/4 ton snouts that use wide 5 wheels, or 2 1/2" Grand National that use 5 on 5 bolt circles.
the most common wheel studs for these are 5/8" either coarse or fine thread.
The most common axles are 31 spline (will interchange with Ford)
You can have Disc or drum brakes
There are several differential options,
Tru Trac
Detroit Locker
Vari lock
Spools
Although I have never built one as a front axle, there is no reason it can't be done.
Any questions, feel free
