Just got off the phone w/ Strange. The 3.73 gearset is no longer an option on the 12 bolts and 9". From what I understand they are having noise issues so they are being dropped. I ended up getting a 3.90 in my 12 bolt as it is what they recommend in it's place (motive or US gear is what they use).

So if you are thinking about a 3.73, I guess it's a no go. Kinda sucks because that's exactly what I originally wanted in my A4.

Interesting, Ratio will not dictate noise.

I just got 3.70 in my 9" a few weeks ago..? Did they JUST stop doing it?

BTW, mine makes no noise yet..

Yeah they just stopped using them.

I've heard of different ratios from different manufacturers being noisy. Like a Richmond 3.90 is noisy from what I am told.

I really didn't want to get a ratio that aggressive it's still a street/weekend car. I was even thinking about staying w/ a 3.42. Oh well I got it now, I guess it's only another 150 rpms or so. I hope it ends up working out for me.

WTF ever...my Strange with 4.11s whines like a bitch. It isn't the gears...it is their dumbass installers that couldn't set gears if they had a gun to their head.

Exactly. Your gear ratrio should not effect weather or not the gears are loud. Thats all in the install right there.

My 3.70's don't whine at all either.. Of course I'm only at about 400 miles on it.. So gotten on it or launched it at all yet.

I have a terrible whine in mine with 3.73s. Im tearing it apart tom to see what the hell is up with it.

I bought US Gear/Strange 12-bolt 3.73's directly from Strange a while ago and never heard about this. I think it was over a year ago though. Fwiw, my 4.11's whine like a **** too.

The problem is U.S. Gears and what ever they have going on with manufacturing their gears or something..
Moser also use U.S. Gears and is experiencing some problems..

I ordered U.S. Gears 3.73's a while back and they were genuine GM. There was a page in the box saying they could not keep up with demand. These GM 3.73's I got had special instructions and were called a Phoenix cut gear set. Whatever that means.

Exactly, we both know it's quality and setup that cause it....

In my day to day function, I use exclusively Yukon gear. In some cases they are reboxed Richmond, OEM, etc - they only rebox quality gears. US Gear, Genuine Gear, etc are their economy line. Anyway, their F9" 3.70 is noisy, but they tell you that before hand.


I'm getting a very sour taste in my mouth with all this Strange issue.... Up until a few weeks ago, I would have recommended them to anyone - or even bought from them myself - no longer. In fact, I couldn't believe some of the problems I was hearing. Now, as soon I see the Strange name and an issue, I know what's up.

I had problems like you guys mentioned all it took was for me to drive my car while my g/f sat in the back with a video camera for 52 seconds..
Emailed the video..

End result which I received today
Replacement gears, install kit, gasket ect. along with a refund

Wow that's pretty decent. I can tolerate the whine myself, but I don't drive the car a lot, plus it's loud (exhaust) anyways. Mine sounds just as loud as it did during the break in period. I guess I can deal with it as long at the rear holds up, which it easily should. Everything else about the rear I like, other than the price LOL.

I bought the series-4 3.73's. I wonder if these are the problem child or if it's the series-3 3.73's.

I dunno but when I got it last summer they did not offer the ratio at all. Said they wouldn't do it.

Look at the gear and see if the tooth surface is nice, shiny and smooth or? If it's nice and smooth and shiny, then most likely it will setup quiet - if done correctly. If it's bumpy and rough, then your headed for a noisy setup, regardless if it's done right and worse if done wrong.

If you cryo a loud set of gears, sometimes the process will finish them better and quiet them down.

I had them Mikronite processed by Crane already. From what I remember, the surface wasn't rough per-se, but is wasn't smooth. I'll have to look at them again to be sure.
