2.73 to 3.73 (? on required parts)

Somebody who has changed out the 2.73s to 3.73s please let me know what I need to all replace. I was thinking on Richmonds complete Ring and pinion package. Thanks

All you need is the gears and install pkg. I went with Strange $188 for the gears, $88 for the install pkg.
Talk to Madwolf about programming your computer.

to go from 2.73's to 3.73's, make sure you get gears for a series 2 carrier, since the 2.73"s came on serires 2 carriers(most 3.73"s are for a serires 3 carrier), and the bearing kit

I would recommend going with a Strange Gear over a Richmond gear. Richmond gears tend to whine alot ever when set right.
