Hi all, newbie here. I just bought a F350 SD a couple months back and want to install locks on my wheels. My question is what size are the lugs. I've visited a few websites and some are saying M14x1.5 is the size I want while others are saying they will not fit. I called the parts/service of the dealership I bought the truck from and they were of no help.

Anyone here know?

Thanks in advance...

 

What you might consider, do it once and do it right, take one of the wheel nuts to any auto supply store and they should be able to match up a size to match the wheel nut. Might be a good move to buy one anyway because if anything goes wrong ,you have a backup and will know the EXACT size you need.
.Not all problems can be solved over the net, lol.
