Anybody know how strong a factory installed 3.91 Gear set from a 489 case 8.75" Mopar rear can be? How much hp/tq can they handle with 35 spline axles/spool @3600lbs? Making over 600 hp/tq....
Are they a strong steel or weak?
Should I just buy after market gears? I already broke the stock axles!
Thanks
Adam
