Are you sure your gas mileage got better? Or is your speedometer and odometer off now because of the gear change?

how much "getter" did it get?

I noticed a difference when I went from 3.27 to 3.73 in my auto. So you'll notice a HUGE difference going from 2.73 to 3.73 or 4.10s.

As far as an install price... most places seem to charge $200 - $300.

For a street car, Auto 3.73's ,5 Speed 3.55's
For a track car, Auto 4.10's, 5 Speed 3.90's

It will make a very noticeable difference if your car has 2.73 gears, Door Code M, and as for installation, it is moderate with the right tools, such as bearing press, dial indicator guage, calipers, torques qrenches, and repair manual with all the torque and assembly specs in it.

Best mod for the money and most noticeable at the pedal. Don't forget the $10 speedo gear, it'll keep your miles accurate and wallet full.

Why 4.10s with an auto for a track car? There's nothing wrong with 4.10s in a street car.

Btw, how in the world does your gas mileage get better by installing lower gears?
