8 lug, 14 bolt SF to 14 bolt FF

Yes, I have slide off drums. I thought the change was made in 88 and effected all the 10.5" axles, but I've read of people having the old style drum behind the hub more recently. So now I think it must only be SRW 1-tons with the JB8 brakes that got the slide off drums.

My '99 k2500 has slide off drums.

Do you have the 14BFF and JB8 brake RPO?

It looks like I have a SF JB7.

It looks like I have a SF JB7.

If you have a semi-floating axle, your drums will slide off. We're talking about differences with the 14BFF brakes.

Oh, sorry.
