Another plus of going with 3.55’s is the availability of limited slip units. 3.23 units are not offered so you’d have to find a used unit

That was absolutely part of my decision when I saw the ratio break on these carriers. If I buy a posi carrier for the 3.23, I couldn't use it if those gears broke or just decided I'd rather have lower gears. Better to make the decision now and get the 3.55's and the 3.36 and numerically higher posi carrier.

I'm looking at the Dana SVL. It appears they have a very good reputation and are reasonably priced.

Yep, they only make replacement gears and posit units for the series 3 ratios which is 336 and up numerically. I always found that the 323 or the 308 is the perfect axle if you’re not going with an overdrive unit but if you’ve got that extra gearThen 355 or 390 is really nice

FWIW...Auburn Gear sells their HP and Pro series limited differentials in a 3.23. Eaton however, not.
