opinions on rear end 4.10 gears pricing and recomendations?

finally decided to get the rear end done, and im going with 4.10 gears.
the only brand ive found is richmond, so does anyone know if theyre good, or if there is a better option? ( also, if im getting my dealer to install it for me, do i need the install kit they sell as well?)

Also, my dealer quoted me approx $350 to install the above. Is this a fair price?

any info appreciated!

this price seams very reasonable if it is a quiet option...

of course, i now have a few more questions sorry for being a PIA, but is there a noticable difference between 4.10 and 3.91? and also, does this set up require a install kit like the richmond gears do?

It's normally suggested to use the install kits, so you get fresh bearings and spacers to do the job right. The performance is close to being the same with both gear sets. The OEM gears are made by AAM, so it has been reported the 3:91 set is just as quiet as stock, and won't whine like the 4:11 set ...

Richmond started out making 4.10's, then (as I understand it) after numerous "issues", they started making the new 4.11's made out of a stronger material or maybe it was just a different heat treatment process or something. The bottom line is the new 4.11's are stronger and better. I haven't heard of any failures yet with the new 4.11's, but I guess anything is possible. I'm not even sure if they are still making the older version of the 4.10's anymore, and I believe their 3.73's and 4.33's are still being manufactured using the older (inferior) materials or processes. Regardless, the Richmond gears have had their share of "issues" in the 5th Gen Camaro.
As previously stated by SlingShot, I would definitely recommend the Lingenfelter/AAM gears. They are expensive, but at this point, more reliable than the Richmond products. And yes, an install kit is highly advisable for either.
If you can wait, U.S. gear is supposed to be releasing their gears (4.10's included) in Sept. Not sure on prices yet.
Lastly, if you're going to be tearing into the rearend anyway, I would HIGHLY advise adding the Jannetty Posi Mod, Jannetty Billet-Machined Main Caps, and probably the LPW diff. cover. Just make sure your dealership has plenty of experience upgrading these rear ends, I hear it's extremely "tricky". BTW, I think $350 for install is pretty cheap!! Good Luck....keep us updated.

I've put over 18K miles on my Richmond 4.10s and have had no issues or whine from day one (and I've loved every second experiencing the night & day difference!)... Like others said, $350 is a very good deal for installation, esp. If a a dealer is doing it for you.

All gear installations require an install kit. There are parts that are not reusable and have to be replaced. A "half kit" includes the absolute minimum you need to do the install. A "full kit" includes the same plus some other parts that are a good idea to swap due to wear etc..

$350 for a gear install is dirt cheap, especially from a dealership service department. It is a good 6-8 hour job. I would verify that they have done gear installs on these cars before.

Go 4.11's not 4.10's if you are going to go Richmond. My gears are awesome and the car should have came with these in the first place.
