I have had the SLP (GM) 3.73s, in my 10 bolt for over 50K and they are still quiet. NO gear whine. And for anyone wondering, the SLP gears are GM gears. Unless something has changed, I purchased mine about 4 or 5 years ago.
I just bought the richmond set off of summit and it came out to 319.95$. And thats the master kit comes with the ring and pinion,oil,shims,new bearings,movie on how to do it,and the gasket and everything else needed. I went with the 410's I should have them tomorrow and putting them in by the weekend!!! Super excited let you know how it turns out

i have a strange 12 bolt in my car with richmond gears and it is loud as hell right now i dont know if its the set up or the gears. im going to redo it myself and see if that helps it out if not its gear change time
genuine gm gears so i THOUGHT, were AAM(American Axle Manufacturing), same guys who make lt1 drive shafts I would never thinkof running any gear but genuine GM's, aka AAM.
well, when I sold my new 3.73's to get some new 4.10's, I couldn't find AAM' that were B-body ABS friendly. So I went with presision gear.
Also note, that my rear end is not a 7.5" tooth pick. but rather an 8.5"

I was going to go with Motive's "Thick Gear", because of the 2 series carrier but I called Summit racing and they said their own brand is made by either Motive or Richmond. So I saved 50 bucks and bought the summit set of 3.42's. They are really quiet with a very faint whine after about 70mph. You really have to listen for it to here it.
Summit brand here as well. Mine are dead quiet.
