Looking for 3.73 gears
I believe the truck is running 2.93 or so at the moment in the 12 bolt. I'd like to move up to 3.73 gears. A few questions..
1. What brand/make/supplier should I look for? 2. Will I need to change to a different size carrier? I'm currently running a size 3 if I'm not mistaken. Some people say I can still use the size 3 with 3.73 gears, and not have to move up to a size 4. 3. Anyone in North Texas (Dallas), that recommends a shop or an individual to do the swap at a resonable price? Any input would be greatly appreciated. Thanks, T. C. |

Trinic,
I know in my 12 bolt rear I had to switch carriers going from 3.73s to 3.07s. So, by extrapolation I would say that you'll need to do the same thing. If you are looking for a used carrier or gears, I have them available. Brian |

I'm in Wylie as well and I know that speedtek does them as well as 4wheel parts on Plano Road. Also you might talk with Ryan (67SS_396) on the other board as well. He might know of a guy that can help you out. I'm wanting to do the same thing as well.

Website
If you want some real useful info on this, do a websearch for STRANGE AXLES and GEARS. I believe they are now known as U.S. Gear. These people have been around a long time making gears and axles, quality is excellent and thier prices aren't too bad.
Here's the website: www.usgear.com Last edited by littlebubba; 04-30-2003 at 01:57 PM. |

They make a 3.73 gear for the #3 carrier. I think it's $20 extra.
