About to buy 4.10's and posi unit Ive installed many gears (8.2 and 8.5 rears) but i hear that with a torsen posi rear ill need to buy a paddle kit to make these gears work? There motive gears, is this with the torsen posi unit only
EDIT: Is this only for the series 2 carrier? Does that mean the series 3 carrier with 4.10 will work fine?
Is there a difference between the Torsen and Auburn units with 4.10?
Sorry for the questions, just checking on stuff

4.10's in a 7.625 rear will require you to do one of three things.
Grind a flat in the ring gear.
Grind the cross pin (auburn, etc) Or grind the paddle (torsen)
Get a two piece paddle block and grind nothing.
The gear sits above the hole where the block or pin goes in, it doesn't matter what series it is, what matters is that it's 4.10s

Look at it this way, the pinion gear centerline is the same no matter what ratio you have, 2.41's to 4.88's all the same c/l
Put a smaller diameter pinion gear in there, the ring gear needs to move closer in order to mesh with it. Usually the ring gear appears thicker to make up for the space between the flange on the diff to the pinion gear.
While all this is going on, moving the ring gear teeth toward the center of the rear, the cross pin or thrust block location remains the same. At some point the ring gear moves so far to the center that it's going to partially block the cross pin or thrust block from going in.
