11 inch drum ? - 03/15/13 02:23 AM
Going with 11 inch rear drums on a 8.75 and was wondering if any other rear axles with 11 inch drums will fit the 8.75 (9.25,8.25,Dana 60,ect).
11 inch drum ?

I used 11" Brakes from a 8-3/4 C-body wagon on a dana 60& fit fine. My 9-1/4 B-Body looked the same but didnt actually try to switch them

As long as you keep the correct drums with the correct backing plates they will interchange. Had a guy tell me all 11" C body stuff was junk. He was trying to use 11x2 B Body backing plates with 11x2.5 drums. Another 20 yr old know it all....

11" drum/backing plates from an 8 1/4" rear will also work on an 8 3/4.

As long as your not putting them on an A body 8-3/4.
8-1/4, 8-3/4, 9-1/4, DANA, all should interchange.
I've even used F body 7-1/4 rear brakes on an 8-3/4.

Switching to bbp on a 8.75,I have 8.75 11in backing plates.So will only 8.75 drums work with my backing plates? Or do they all interchange?

Are you changing axles?
A body 8-3/4's have a couple unique characteristics...backing plate offset, drum flange, center register, etc.

A Body 8 3/4 housing? A body backing plates won't work, you will need a set of B,C, or E body. You need to know which 11" backing plates you have to get the correct drums.

The housing is from an Abody and I got the 11in x 2 1/2 bp from a Cbody,I will be getting bbp axle shafts also.

If they were together on a C body and you change the bolt pattern on the A body to bbp you shouldn't have any issues.

So a 7-1/4 setup from an ebody would work on a 8-3/4? If so I need to pull the brake setup before the junk man hauls it off.

They should fit.
I never scrap brakes unless they are worn out.
At least a dozen sbp and lbp sets on the shelves.

I think I may have confused everyone,what I have is a 8.75 and am wondering if 11inch drums from any other mopar axle will work on it. Or do they only work with there own backing plates,shoes,hardware,ect?

Re: 11 inch drum ? - 03/17/13 03:08 AM
Brake drums are not specific to the axle. If you have 11 x 2 1/2" backing plates, you can run any '65 and newer Mopar 11 x 2 1/2" drum with the same bolt pattern.
