Anyone using 6 to 5 lug adapters? If so what brand and are you happy with them. I have a set of cragars that I may want to run in the future.

I have a set. They are a two piece design use 12mm 1.5 lug nuts and are about 2 inches thick. so they will push the wheel out. I was going to use them on my 60 , but the Cragers would hit the rear fender. Up front they were ok. I just didn't feel comfortable putting a lot of load on the week ball bearings the 60' has .
I did a rear end swap to get the 5x5 bolt pattern and some day I'll install my disk brakes to get the 5 lugs up front.
(yes I am running 5 lugs rear and 6 lugs up front

)
I paid 150.00 plus shipping on ebay. Now they are collecting dust
pm me if you want to try them

Scott, that is a nice looking truck. Do yourself and your family a big favor. If you want 5 lugs do it the right and safe way. Don't put spacers on your wheels. You are too valuable to everyone. Tomorrow is Thanksgiving think about it. Mike.

I've never run them myself, sold my project car that I was going to use some on before I got to that stage. Here is what I've learned.

Use good quality billet adapters. I've seen dually trucks use these and hauled some fairly good sized loads.

Good adapters will run you about $150/pr. They will push your wheels out the same thickness the adapters are made. Usually 1" is the thinnest that can be made although I do recall hearing of some that were 3/4" thick. The lug nuts for the truck have to be less than the adapter thickness or the wheel won't sit flush on the hub.

By the time you buy the quality adapters and wheels with the correct offset for the adapters, most of your "conversion" could be paid for. If your wheels don't have the correct offset to take into account for the adapters, they won't fit anyway.

Example - A wheel with a 5.25" backspace would be needed for a 1.25" adapter which would be the same as a 4" backspace wheel.

Best bet, do the conversion right and run more commonly available wheels.

Agreed on the conversion.
