I just swapped gears into my existing differential.It was really easy.

Thanks, just wondering which way you went with your swap :thumbsup:

I've had the vortech v3 and 3.91s for about 3,000 hard driven miles with no issues. I'm putting 565 to the ground on 22s and no problems other then traction. Go with the 1LE gears and you won't be disappointed

I put the 3.91 gear and a truetrac in my car. Been in for a couple thousand miles and quite a few passes down the dragstrip on DR's. I couldn't be happier. I'm not making monster horsepower though.

Richmond gears are a hit or miss. If you read over past threads people will go both ways. The cliff note version is like this. Richmond gears used to be really great gears at one time and for quite a while. Somewhere down the line they were bought out and the quality was shot to hell. That's why a lot of people are against Richmond. However, they were bought out again and supposedly good quality is going to go back into the gears.

If you plan, and are entirely sure that you're going to go FI with the car, then save yourself the time now and drop down to LPE 3.45, 3.70, or if you really want to stay with Richmond, 3.73.

For me personally, I'm still using the factory 3.45

Me as well. Never again will I use Richmond even if the quality has gotten better. My advise to the OP is get the GM 1LE 3.91's or the GM LPE 3.70's. If you break something with those gears it will most likely be a axle or entire rear end not the gears themselfs. I think the 1LE gears can be had for as little as 300dollars.

Take the gears to a rearend guy, get the Jre posi mod and end caps!!!!

I had my 3.73 richmonds break on a 1-2 shift on street tires. snapped off 5 teeth. i was told that it was from "shock load" and not warrantied.

LPE 3.91s installed and so far so good. No noise from these either unlike the richmonds. Same Installer.

This is exactly what you should do. Screw Richmond gears. I've never heard one claim of the LPE gears breaking. All you hear about is the trash Richmond gears breaking.

Absolutely agree.

Motive, richmond, etc. All in the setup. We see incorrect setups all the time with whine or borken ring gear teeth from excessive backlash.

ONLY have a proven shop (that has been doing gears for years) do the install. It is something few do correctly.

:thumbsup:

Ok so the Dealership put the factory third member back in and now I have a third member with broken 4.33's. Who do you guys recommend to install a new set of gears that will warranty them?
