WTB 3.73s for my SS......

[Apex Motorsports]

We have them in stock and ready to ship. If you have any questions just let me know. PM on the way.

If you have a naturally aspirated M6 you may want to consider 4.10 or 4.30 gears. 3.73s are only a 7.5% change. 3.73s are very aggressive with an A6 because of the deep 1st gear.

4.10s are a good option for the M6 cars, even daily drivers. By upgrading the factory 3.45s in a stock M6 equipped Camaro to 4.10s you will realize an equivalent torque gain of approximately 20% or 84 rear wheel lb.-ft. of torque and still only turn 2000-2100 rpm at 70-75mph. We have had more than one customer who do a lot of in town driving report an increase of 2-3 MPG after adding 4.10s. The gearing and extra gears in these cars makes it possible to go to gear ratios that were once thought to aggressive for daily drivers.

See thread http://www.camaro5.com/forums/showthread.php?t=92578. I've been thinking gears but at this point all I would go with is the pricey but proven Lingenfelter AAM ( OEM ) 3.70 gears. The $800 price tag is a killer though.

I would consider 3.90 gears for a M6 but nobody makes them. Changing to 3.73 gears with a M6 is a waste of time and money. Just not enough torque gain (7.5%) with those big tires.

4.10 is awesome in the M6 cars. Upgrading the factory 3.45s in a stock M6 equipped Camaro to 4.10s generates an equivalent gain of approximately 20% or 84 rear wheel lb.-ft. of torque.

The 3.70 ring and pinion is $699 from LPE. I don't think that is significantly more than the competing 3.70 ring and pinions. Our 3.70 ring and pinions are made by an OEM GM production supplier to production tolerances and specifications.

For AT cars switching to the MT differential can be a fairly cost effective option as well (since you can get a complete assembly for not a lot more than the gears and install kit).

Here are the ring and pinion, differential and install kit prices/parts numbers from LPE:

LPE part # Product Description Retail $
92246988, 2010 Camaro SS 3.45 differential assembly $ 999.95
L380021410, 2010 Camaro SS 3.70 differential upgrade (with customer core) $ 1,995.00
L380031410, 2010 Camaro SS 3.70 differential assembly $ 2,895.00
L380011410, 2010 Camaro SS 3.70:1 ring and pinion $ 699.95
L380041410, 2010 Camaro ring and pinion install kit $ 199.95


The install kit is a full install kit with the OE shims, bearings etc. It is far more complete than any competing install kit. It works with the factory gears, our 3.70 gears and the Richmond 3.70 and 4.10 gears.

So I can buy the LPE ring and pinion and install kit for $900 and install the gears myself or have someone local do it OR purchase the LPE 3.70 differential upgrade (with customer core) at $ 1,995.00. So if I understand this correctly I need to ship my 3.45 pumpkin to LPE along with a check for $1995.00 ( plus shipping in both directions ) ?? Doesn't over $1000 to set up a R&P sound high ?? This doesn't include labor to remove the pumpkin which some will have to pay ( I do my own work ) and down time of the car.
