The Stovebolt Site Forums The Parking Lot Big Bolts Wheel spacers on a 1-ton GMC

We got this question a while back. Can anyone help Chris out:

I'm new to the site, i have a 60 1-ton GMC flatbed and just got a 66 GMC 3/4 ton 4x4 (will send in picks soon for the Gallery). My question is on the 1 ton, it has 3/4 ton wheels on it right now, but I want to put the duallys back on, they came with it. There was wheel spacers for them but they looked homemade. Were there wheel spacers on the back in 60 or should I not worry about it?

Tanks in advance for any reply,

There were no spacers originally. If it has oversize tires someone might have put them on to keep them from rubbing each other. Check to see if the inside tire clears the bed. That is generally where interferance comes in.

My 1958 1 ton dually does not have wheel spacers on the rear, but does on the front. I was not alive in 58 (more or less buying this truck new) but it all looks pretty original to me!

The rear axle (Eaton HO 72) is hub piloted, 8 bolt, 1/2" thread (NOT 9/16). The front axle has a spacer from the hub that puts the front wheels out about 3 inches wider. This makes the front wheel track about in the middle of the rear dual wheels.

This spacer is really connected to the hub tight. It bolts to the hub using the 8 hub lugs. It has it's own 8 lugs that are offset slightly from the hub studs.

I can't recall the exact post a while back when this was discussed, but someone else with a similar year dually had the same setup.

the front spacer is factory to allow the 1 ton wheels as they are offset. no spacer on the rear from the factory. what may happen is someone using a 3/4 ton rear and trying to use 1 ton wheels. what happens is, the tires rub the springs. if spacers are used between the rear wheels, then perhaps somebody tried using oversize tires.
