14BFF disc brake conversion...need new lug bolts?

[fortcollinsram]

I am converting my 14bff to disc brakes...While awaiting the caliper brackets, I get new rotors and calipers and bolted everything on the axle... But I noticed that my lug bolts aren't sticking out very far...Does this conversion usually require new lug bolt due to the extra thickness of the rotor when compared to the stock drum? Thanks for your help gang...BTW it is a 3/4T 14bff that had 11" drums...not the 13's...

i didnt need any and a friend didn't need any--but who knows every truck is different---test fit it and ef et works --go with it.

If you had the 11" drums like you said, yes you will need new studs. I would get them for an 85 3/4 ton suburban since I know those are the correct length. Also you will need to machine the outside diameter of the head of the stud by roughly .110" for it to fit in the recess of the rotor. I just did this conversion on thursday. My brakes work excellent now.
