I had saved several older discussions on choices for drive ratio options but lost them in a recent computer crash. In addition to the debate about ratios, they also included discussions about which was better, final drive or chain/sprocket.

We've had our GMC for 5 years but were unable to use it. That may be changing and I want to consider a toad and like most before me, realize the stock gearing isn't well suited.

If someone can point me to them again, I'd appreciate it.

Go to our site under final drives, you'll see the chart.
The hottest gear to use for all around for both engine is the 3.70.
Lot of the people are also including the LSD in the final.
We have the most awesome warranty program that cannot be met by any supplier.
3,000 people cannot be wrong.
