3/4 vs 1/2 ton...need suggestions
I have a '69 c20 LWb 2wd. Love the truck drive it everyday. What I don't like it the Eaton rearend, geared to low, and the lack of options with wheels. I kinda wanted to keep it original, but I don't really every plan on selling unless something really comes up. I guess what I'm asking is are there any pros/cons about doing this. The only real hauling this truck will do is getting stuff to build my garage, which will be used to tear the truck apart so after that, it won't hauling much. thanks

Re: 3/4 vs 1/2 ton...need suggestions
I have a '67 C20 and I swapped out the 4.56 rear Eaton for a '72 Dana 60 with 3.54 and it made a huge difference. I also installed C10 springs and the ride is much better and smoother. I kept the 8 lug wheels because I have stock wheels and they are fine for me.

Re: 3/4 vs 1/2 ton...need suggestions
The 3.54 D60 was the first thing I did upon taking possession. I haul firewood, so I've left the 3/4T coils and helper springs in place. It's a daily driver.
I'm happy with some American Racing wheels that I found a couple of years ago, but I'm really easy to please on that front.

Re: 3/4 vs 1/2 ton...need suggestions
the dana rear is a good bolt in swap if you really need better highway ability. personally i like the eaton for its looks and strength and so i just did the 4.10 swap, especially since i plan to tow with my 72 burb c20. i can actually drive it at 50-60mph now. but i still plan to get a b/w overdrive on that saginaw eventually.
i believe the worst (relative term) part of the ride on my 3/4 ton truck is not the stiffer springs, but rather the lousy vintage shocks (low original miles). i'm thinking if i get some modern shocks on there that are tuned right then it will ride really nice. my suggestion for you if you want to maintain 3/4 ton capacity but get a softer ride, just swap out the front coils (the 1/2 ton hd units might be a good choice) and leave the rear alone....that is where the weight goes as the front stays pretty much the same. my dad put 3/4 ton coils on the back of his 72 burb c10 back in the mid 80's and it still rode nice. it did sit like an old school drag racer but that was perfect for towing our heavy trailer. i prefer rake over a leveled truck anyway. i like the stock wheels & hub caps on on my 8 lug burb but there are some nice factory gm rims and aftermarket units too that would look good on these trucks. |

Re: 3/4 vs 1/2 ton...need suggestions
Thanks for the suggestions, looks like I'll start looking for a new rearend. I guess should have gave some more info. This truck isn't going to be slammed, maybe not even lowered, I'm just trying to clean it up, lower the rpm when on the highway, and get disc brakes. This sites been a great help, as this is my 1st truck like this, even my 1st 2wd. Building Jeeps is my other hobby. Thanks again.

Re: 3/4 vs 1/2 ton...need suggestions
the best setup i would suggest for your app then....
get a 2000+ 14 bolt axle. it has factory disc brakes w/ better e-brake and all the r&d, not some aftermarket kit retrofit deal. also, you get a beefy 11.5" ring gear and the track width is a bit wider which will help push the wheels out to more closely match the front track. good gear choices and a locker diff available too. only thing you have to do is get trailing arm perches, track bar mount and shock mounts welded. i was trying to stay a bit more factory correct with my burb (and i don't care for the dana axle), but this was a VERY tempting idea to me. |
