I bought a center section from quickperformance before the winter. Has a spool 4.11s 31 spline axles in a Yukon iron center with aluminum pinion support. I did the heat cycles and 500 mile break in now there are about 2000-3000 miles on it some hard driving and track passes, and the thing screams. Loudest rear I've ever heard louder than the 12 bolt I had. So I want to put a new set of gears in it to hopefully resolve the issue. What manufacture tends to have quality gear sets that stay quiet?

This could be a subjective thing too, and my exhaust has always been loud, but I have Moser gears in mine and dont hear anything. After a track day they get plenty loud on the way home but quiet back down the next day.

I dint think this is subjective. My friends can hear them driving along side of me. When I say they scream I mean they sound like a consistent train horn

All aftermarket gears are going to have some kind of gear noise some are worse than others. Do you know what brand of gear you have now?

Im not sure what brand gears quickperformance uses, there was no option to pick the brand gears just the ratio. I can understand howling but this is ear bleeding so anything would be an improvement

i have my 9 inch from rear end specialties and it howls around 60-80mph, all i do is open up my cutout drown out the sound

any recommendations on a brand to give a try..i dont care if its not silent but mine is unbearable at anything over 20mph so i think its definitely a little out of whack.

A lot of people have luck with motive gears I believe that is what is in mine.

I've had good luck with Ford SAP gears . Running a set of 4.30 I set up that are nice and quiet.

I've run Yukon, US Gear, Motive and Richmond in my 9" in the 3.70-4.56 range. All were set up correctly with great patterns. Richmond's made a slight whine from 65-75mph but quiet otherwise. Setting everything up correctly is the most important part.....
