Changing gears

I have this carrier

EATON
Aftermarket Carrier Style Clutch-type
Axle Shaft Spline Quantity 30
Carrier Material Steel
Carrier Series 3
Cover Bolts 12
Manufacturer of Axle GM
Designed for 2.76-3.42 gear ratios.

Is there any way to put 3.73 gears on it?
Thanks

Re: Changing gears

That's a great question, unfortunately I don't have an answer. I figure once one guy answers the rest will follow

Re: Changing gears

Yes you can. I just did it. Had the 3:07's replaced with 3:73's. You have to get the thicker ring gear or run a spacer. Photo shows my replacement. Hope this helps.

Sweet. I hate running 1400rpm at 60 on the highway. My 383 and fitech aren’t happy running that low of rpms
