Thread: Ford 9" rear

Tweet

I'm thinking of someday swapping out my 10 bolt GM rear for a ford 9". I will be using 300-308 gears. What gear ratio range rear do I look for to be able to use those gears If I don't find one with those gears?

Jack.

If you get a 9", you can have any ratio you want. DTS will build you any width, gear and brakes you want, among others. Just do a search for Ford 9", the web is your friend....

The most common ratio for the 9" is 3.00/1 in passenger car applications.

3.10 was a pretty common stock gear for those

Thanks guys,

I am not a ford rear guy but I was under the impression that the carriers were different for different gear ratio ranges. Maybe not, please inform.

Jack.

you can go from a 2;50 to a 6;50 with the same 9 inch punkin

Hoss429,

Thanks.

Jack.

Speedway has tons of stuff for the 9"

9 Inch Ford Pro Ring & Pinion Gears

They go from 3.5 up to 6.5 gear ratio for around $150

I just put rear disc brakes on my 8 inch for less then 1/2 what you would pay for some of the kits out there. They would also work on 9 inch with the small bearing - just ask if you want more info.
