Thread: Looking at a rearend

Tweet

I am looking at buying a rearend! What things should i look for? Good & Bad?
Thanks

I prefer a shapely one
This looks about right!

That is a good point!! Cant disagree with ya!!

I had a hunch that would get some interest, nothing like a nice looking rear end.

i like the way the center section is set up as well

The "axels" are only 28 spline...weak ...and the center section is too small.

Is that an open diff....or one of those posi-traction units....

Depends a lot on what kind of car and how much horesepower you're putting to it. Also need to know what you use the car for, and how hard you drive it, and what transmission you're using....

Anything used for a hot street set up, and/or an occasional use at the track or on the street with some good sticky tires would warrant a 9" Ford, Dana 60, or a 12 bolt Chevy. Usually cheaper to put in something strong enough to take some abuse then it is to keep breaking stuff in a light duty unit......

It seems alot of folks here have been using the chevy S-10's. I'll be using a 9 inch ford for my 48 ford truck with 460/c-6 auto tranny.
Here is a beefy one that will take anything and bounce back!























Fooled yah, I know what you were thinking!

Well actually I have a 454 pushing 550 horse without spray. a turbo 400 trans(not beefed up yet). But i saw a 12 bolt gm open 331 gears, i figured i would change the gears anyways. It has no backing plates but I heard thet the ones from a 10 bolt will fit? I was planning on running 410 gears? What you guys think? Thanks, Brian

A 12 bolt, if put together with the right pieces, should be plenty strong. As for the brakes, by the time you locate all the pieces and do the necessary rebuilding you'll almost have the same money in them as some of the more inexpensive disc brake packages..... Check out Speedway Motors, they have some that are very reasonable and work quite well!!!

If it's going to be on the street, and not a lot of long distance cruising the 4.10's would be fine. If you plan on some highway driving, might want to be down in the 3.50-3.73 range so you won't be zingin' the engine quite so high when you're on the highway.....
