Brake drum question

[rusty ol ranger]

I read somewhere that 9 inch drums are finned and 10 inch drums are not.

Can anyone verify?

That's my understanding also...

Exception... Aerostar 10 inch drums are also finned.

I need to order wheel cylinders for rusty....i was curious cause mines got the heavy spring/high GVWR package but finned drums...im glad i checked cause i assumed they were 10's

You could always upgrade to 10” drums… my blue 2000 Ranger came from the factory with a 7.5” rear and 10” drums. Just a matter of swapping backing plates and all the brake hardware. I ended up swapping the whole axle for an 8.8 with limited slip years ago.

I'd just measure them before ordering parts. I don't recall ever seeing finned 9" drums.

To late.

My bronco also has finned drums, and those are 9 inch. Partially why i double checked. My ranger has a higher GVWR then the bronco lol...despite being probably 4 or 500 lb lighter

Meh. It stops good enough for me
