Following, I’m looking for an eight and three-quarter sure grip rear end for my super B. It came with a 489 case and 3.23 gears however I’d like to go to 3.5 or maybe 3.91

Don’t put a powertrax locker in for street driving.They ratchet going around the corners but are locked while going straight, I have the one I put in with Richmond 3:91 ratio that I’m taking out to go back to 3:23 for my RT , in away I’ll describe it like a Detroit locker only worse. Very positive traction!

Pricey but, the Torsen (sp?) geared units are the ultimate.

Dr. Diff has the superior customer service and knows Mopar. For any mail-order axle needs (other than like a custom Moser or something) I wouldn't even consider anyone else...

Eaton TruTrac. I have one in both my cars. Love em. No special fluid required and quiet.

Dr. Diff is the man you need to talk to, he will get you squared away.
