Original NAPCO hubs or No? Guru input needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**GMCNUT** · 03-06-2015, 06:37 PM

So my 57 Chevy NAPCO truck has these WARN brand 4" front hubs on it - another board member says he has 2 NAPCO 4x4's and a set of normal 6 lug 1/2 ton truck wheels will fit on either of his trucks, but mine has 4" hubs that will not fit through the center of a normal 6 lug wheel because the opening is like 3 3/4" or something instead of 4". So now I am wondering if these WARN brand hubs are not correct original NAPCO equipment at all, and instead have been changed over the years - if so, I want someone among you who knows his stuff to point this out, and tell me what its supposed to have, and if possible, where to get the correct ones, because at this moment, this problem is preventing me from being able to mount the correct wheels and hubcaps.

Is there a NAPCO guru on this board who can say one way or another?

Thanks OrrieG, but so far my membership on the NAPCO forum has been pretty worthless - I get way more responses and information on this forum. I was surprised to find no one on the NAPCO forum able to answer this seemingly simple question if you can believe that.....so onward with the GURU search - somebody has to be a 4x4 nut and know a lot about them or have a bunch of them or something

These pictures show a slightly different hub:

Also this auction:

This page also claims to show regular hubs:

you guys are the best - thank you. I did finally find a NAPCO guru who explained that what I have are correct 56-57 WARN M18 hubs and that from the factory they only had driving flanges that still fit under stock hubcaps even - any locking hubs are an extension to the driving flange as a bolt-on accessory. So according to this guy, I do not need to be looking for special wheels because all 55-59 wheels fit over these M18's (despite the 63-66 rims I already tried not fitting) so once I have a chance to try this out, I should be A-OK and good to go - thanks a bunch guys!
