Title: Correct specs for 2.5" KH Drums on 65-67 Shelbys?
Post by: Kent on July 01, 2024, 06:06:07 PM
What are the corrects specs for new KH 2.5" drums measured and what is the minimum they should have. I read different values in an manual, another book and a forum so I´m not really sure or maybe I´m just to picky.

I have found typically 10.060 to be the maximum . FYI 68 Shelby did not use the 2 1/2 brake drum.

Thank you Bob so what do you think or heard is the highest diameter reading that should appear for safety on the KH Drums?

Shelbys used the 1 3/4" brakes in 1968

They should be no larger then 10.060 as I posted in the first response post to your question.

Ok I will keep that for my files. Did someone ever measured a set of brand new drums if they are really exactly 10.000 that would be interesting. Thanks Bob and Coralsnake for the fast answers.

I have never measured but It would be counter intuitive to think that a 10 inch drum when new would be other then 10 inch's .

I measure the left over meat on the inner sides on some KH I have and it looks more like 10.010 but it's tough to measure it 100% correct so yes maybe its 10.000 or 10.005 after they were machined in the production who knows.
