What brand ring and pinion gear set are you guys running? I want to go with 4.10's but I don't want to pay the $587 for the GM gear set! Who makes a good reliable gear that isn't noisy?

 

havent had a problem with my 4.10 Richmonds. but they are noisy every once and awile

 

Don't get the Genuine 4.10 gear set then, They whine a whole lot but they are holding up quite nicely so far with the Eaton posi!

 

Get yoursellf some Motive Performance. That is what I have on my extended and they are quaet as cat. I am not sure how true this is but I hear "Gears don't whine, bad installation does".

I've got about 60k on my richmond gear 4.10 no whine yet.I agree proper install and lash setting is a must. Jim

 

I agree on the proper lash and install but the gears still whine depending on the cut. I guess the new GM gears have a 5 angle grind. I'm still not paying $587 for a set of gears! The install is going to run me about $320.

 

a friend of mine has precision and i've never heard a noise from them at all

 

call randy's ring and pinion! 1800-292-1031
Great guys up their. I called to price new gears for front and back (4wd) as well as an eaton posi.
at first their price was high. i just said hey look, i can get same stuff for alot cheaper.
he said well. how about this. and quoted me a price about 200 bucks cheaper! He even though in discounted shipping. just dont let them run over ya and be nice. they can really help.

 

I am with big-randy's r and p is the only place to get rearend parts. They have good service, are knowledgeable and sell quality stuff. I bought a set of 3.73 Yukon brand gears from them for my street rod and they set up easy with NO noise at all. A lot of aftermarket gear sets whine because of the way they are cut so be aware of that.

 

Having just gone thru this last week, it has nothing to do with the gears themselves. It is how they are set up. There are 2 grind & 5 grind gears. 2 grind gears are biased towards the toe and heel of the ring gear, and 5 cut gears have no bias. If you buy 2 grind gears and the installer tries to set them up like 5 grind gears you will have noise. You will get noise from 5 grind gears if they are set up with bias towards the toe & heel. You just have to know which kind you have, and make sure your installer knows how to set them up correctly. I bought my gears from Power Train Truck & Auto Parts. Gears were $159.95 plus shipping. They are GM 2 cut gears, and work great on my truck now that I know the difference in grinds. They are great guys to deal with. They also sell the install kits for our trucks. Their # is 1-866-589-GEAR.
