The Stovebolt Site Forums The Shop Area Driveline 1949 GMC 1 ton axle replacement?

I got a 49 gmc one ton truck with a 9 ft bed. I want to switch my ring gear so I can actually drive the truck. Any suggestions?

Dan,
In the tech tip's, there is a very well written article to answer your question. Also, Grigg is actually documenting his project on his 1-ton in the project journals, and walk's you through it. A must read. I have done the pinion upgrade on my 1-ton as well, and it's a wonderful thing. Easy also. The hardest part is finding the donor carrier section. Good luck!

Dan,

Check this topic. Then make sure to send me a PM so I can add you to my list of people who want them.

I have been hooking up people with swaps, including the ones you'll see in Grigg's article, so your old one may be desireable to someone else. Also I am waiting for an answer from someone who says he has a cache of 4.10's that would only be for sale, no trades.

The other option is to find a cab and chassis GM 14 bolt and swap the whole thing. Grigg can point you in the right direction on that. I learned of it from him in the first place. I will be going that route also.

4.10s are very scarce. If you run the stock 17" tires, a 4.56 out of a 3/4 ton will do pretty good. And they are every where.
