Re: Upgrading to 3:55:1 in AD
Check out Patrick's. Despite a recent thread here, he's taken pretty good care of me, and both he an his son, Philip, are a wealth of information.
The 3.55 kit we bought from him was complete and perfect in every way. Now if I could just get the rest of the truck finished so we can check it out on the road.

Re: Upgrading to 3:55:1 in AD
As long as you have it apart any bearings that look questionable. Use a dial indicator and take some measurements for play as you disassemble. You will obviously need seals and gaskets.

WHatever bearing you don't have on hand will be the one you need. 2 carrier bearings, 2 pinion bearings.

Re: Upgrading to 3:55:1 in AD
When you change the gearing please come back in here and post your thoughts on the change. Not so much as as the actual work changing out the gears but the difference in performance. Thanks

Re: Upgrading to 3:55:1 in AD
I'd agree with putting in new carrier and pinion bearings when doing the gear swap. They may come with the kit as I have never checked the kit out to see if it has bearings, seal (if needed) and gaskets. I'd think seriously about axle bearings and seals too at the same time while it is apart. Then you know everything is fresh and should be good for a lot of miles and years.

Re: Upgrading to 3:55:1 in AD
If you buy the ring and pinion as well as the install kit from Patrick's, it's got every thing you need, including the okie bushing for the front of the drive shaft, bearings(pinion, carrier, and axle)shims, gaskets, the gasket kit for the bell, and even the tool you need when installing the driveshaft/pinion assembly back in the torque tube. All I had to buy extra was gear oil.

Re: Upgrading to 3:55:1 in AD
I found the ring and pinion for 350 with free shipping. So my plan is to get every part replaced while they have it torn down
