Title: 5 LUG TO 8 LUG CONVERSION???
Post by: kfoz on August 29, 2015, 07:39:33 am

I WOULD LIKE TO CONVERT MY '76 C15 5 LUG OVER TO 8 LUG SO I CAN RUN THE NEWER FACTORY ALUMINUM WHEELS.

I know there are wheel adaptors/spacers out there. 

Any input regarding brand, thickness of adaptor??

Thanks all!  :)

All I would like to do is run 8 lug adapters. 

Any other info is most appreciated.

Would something like this work?

  Although you have to be suspect about any off brand thing on ebay.......

i wanted to install some later model 3/4 ton aluminum wheels on my 1/2 ton, but after pricing it out---adapters, wheels, tires (because they were 16") is was about $400 per wheel and i decided it wasn't worth it.

But those later model 3/4 ton wheels look fantastic on a square.

Yes, that's exactly what I was thinking BUT I wanted to know if anyone had any experience with the 5 lug to 8 lug adapters.  I would buy quality billet ones of course.

PLEASE CHIME IN EVERYONE!

Thanks all!  :)

do you plan on hauling anything? how much if so?

Title: Re: 5 LUG TO 8 LUG CONVERSION???
Post by: kfoz on September 05, 2015, 04:43:44 pm

Once in a while I may haul a 1000 lbs or so. My truck does have the F44 Heavy Duty Chassis AND coils were added to the rear.

i would get a hold of the company who sells them adapters and get some numbers from them. they should be insured since they are something for the suspension and should have a rating on them.

Understood,  thanks much! :D

Post by: kfoz on September 05, 2015, 04:56:13 pm

On another note, the billet adapters are 2" THICK.  I'm hoping to go with the factory aluminum 16" 2004-2009/10  10 hole wheels and use 285/75-16s OR 265/75-16s.

The adapters would work good with the late model wheels

If you put late model wheels on without spacers it looks goofy cause it puts the wheels too far up under the fenders

Cool!  I sure hope that's the case because again,,  the adapters I'm looking at are 2" thick.

Thanks again!

Well, you asked to chime in......so:

i think i read that some more reputable companies don't recommend using adapter if changing the number of lugs.  In other words using an adapter to change from one 5 lug pattern to another is ok, but going from 5 to 6, 5 to 8 etc. not recommended.  Don't have time to find the thread right now.

2) i wanted to switch to these wheels, but it was $400 per wheel (new wheels, tires and adapters):

Well , , ,, ,

I ended up buying an '83 C20 for all the suspension parts(14 bolt rear, 2 piece drive shaft, lower control arms, front springs, to put under my dry Arkansas '76 C15 ! ! ! BONUS TOO-- fairly fresh original 454/400 drivetrain!  I'll be parting out the rest I think(dual tanks with switch complete, solid fenders & hood, very nice front bumper, complete A/C system, interior lighting, glove box door & inner plastic(a/c), complete jack assembly, grill, some interior parts, etc)
