3.91 gears questions - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

SynergyGreenSS · 03-02-2016, 12:03 PM

I'm planning on having 3.91 gears installed on my car once I know we won't have any more rain (hopefully soon). I saw the gears on phastek for $309.95, and the install kit for another $200. Do I need the install kit? What does it do? How much should I expect to pay for labor? Will it improve my 0-60, and by how much? Thanks for your input everyone

Do your self a favor and avoid after market gears, GM gears are nominal and chances of winding up with a howler are greatly reduced.....

I was planning on getting oem gears and having them installed at the dealership

Can't speak for 0-60 as I haven't measured. Seat of the pants is definite.

Not sure if the Phastek kit comes with the speedometer recal code or not either. The GM kit comes with one or if you get it through Janetty apparently he can do it as well.

Cheapest route is to buy the gears and install yourself. If you can't, then pull the pumpkin and take it tome someone to install and put the pumpkin back in yourself. If you can't do that either, the dealer is going to cost you $1500 or so for everything.

Seems pretty unreasonable.. My dad is a divorce attorney and he's handling a case for the owner of a performance shop in my town so maybe he'll give me a deal..

Hahahaha yeah maybe. It's the labor that kills.

It's not hard to pull the pumpkin and take it someone. Just make sure they set the preload to spec and the backlash is good.

Got my set from Muareen from Rodgers Chevrolet best price anywhere!!!

the kit is for the new bolts sometimes needed for the differential and the shims that are necessary to install to adjust it just right also new bearings are good, as is a LPW diff cover and poly bushings for the diff at least with the rear.

I had a gear shop do it. I just gave them the pumpkin. had less than $700 in it all new GM parts

I just had a shop give me a quote and they said with my mileage, 59k, I might want to do the bearings as well. What bearings is he talking about? All I see in this kit are shims/spacers and a crush sleeve.
