I've searched and searched, nothing comes up. I'm looking for some feedback on GM gears. Are they noisy like richmond or motive? Any problems I should look out for? Should I stay away from GM gears?

Thanx

Genuine GM 3.73 gears bought at a dealer - part# 14091497. The only thing to look out for is their price.

I have Motives in mine without any noise and holding up great. It's all in how the gears are setup. Well with the exception of Richmond. Those gears are noisey no matter what.

If you go to any S-10 boards you could pick up a set of 3.73's really cheap. We usually dump the 3.73's for 4.10's or 4.56's. I'd sell you mine but i'm not sure if i'll use those or 4.10's in the TA yet. Also i've installed 3.73',4.10's. and 4.56's in 10 bolts and never had whine issues.

Thanx appreciate the replies, I'm pending sale on a set of 3.73s from a member here. I just want to make sure I ask questions before its to late. So you guys think I'll be ok with the ratech complete install kit and the GM gears? Any compatability issues??

Shouldn't have any problems, just be aware if they are used they have different set up tolerances. New gears usually set to 5-8 on backlash and used generally 5-14 backlash.

I'm on my second set of 3.73 GM Factory gears and never had any noise at all from them. They have a higher nickle content form my understanding. This is supposedly why they are stronger than aftermarket gears and since they are harder, they're supposed to be louder, but, like I said ... never any noise on either set. Somebody please correct me if I'm wrong.

Only reason I'm on the second set is the tranny shop either did not torque them to spec OR they didn't use loc-tite. Bolts backed out and cracked the posi housing.

Yeah, I had the GM/AAM oem gears installed, and they're quiet as a mouse. It's all in the set up. I got 4.10's. It's the best mod I've done for quickness.

Is this something I want to tell the installer? Would he know what I'm talking about? Or would he look at me like wtf ? LOL

Im not too informed when it comes to a rear gear swap or procedure.
Thanx

If he is a good installer he should already know that, the only reason the backlash is set like that is because we are already assuming the gears are broken in so they can be set a little looser than new if need be. If they are used i'd still set them at around 8 or so, gears set to loose will annoy you and be weaker but set to tight they will whine. So many guys set up gears by touch, if they are good then its fine but most of the time they suck and end screwing up a install. If you trust them to install the gears and know they do good work you shouldn't have any problems.

Gears are all in the install. I've had quite a few gear sets installed, and I finally gave up and went to the dealer, NO NOISE at all. It was well worth my $$$, I've taken gears to a few tranny shops and well, I had a jet engine, and a grumble sound on different installs, after the dealer installed them, flawless.

I'm purchasing the Genuine GM 3.73 gears with the master install kit all for $275. I could get Richmond 3.73's with an install kit for over 300, but I can get all that for cheaper. I hear good things about GM gears, so I'll go with them. Does anyone know if the install kit comes with EVERYTHING the installer will need? I want it to include all the crush sleeves, and bearings etc.

Does anyone know which/how much gear oil I should get, and how much of the GM Limited Slip Additive I would need?

I had GM 4.10s in my 10bolt and they didn't whine at all. The 3.73s in my 12 bolt whined from day one. Not very loud but I can hear them.
