The Final Word
This story's Final Word should be called the Final Math Problem. Check out the math equation we put together to justify the gear swap.

By this math, you can see that we have a projected savings of 2,600 bucks and some change, which is not bad for a few parts and a day's worth of work.

Stock Vs. Regeared Rearend

STOCK GEAR RATIO 4.10
70 MHP CRUISING 2,800 rpm
FUEL ECONOMY 10.97 mpg

Money Saved Via Increased Fuel Economy

STOCK REAREND
10.97 x 33 gallons =
362.01 miles per tank of gas

REGEARED GEAR RATIO 3.21
70 MPH CRUISING 2,400 rpm
FUEL ECONOMY 11.43 mpg

REGEARED REAREND

11.43 x 33 gallons =
377.19 miles per tank of gas

Now There Is An Extra 15.18 Miles Per Tank Of Gas!15.18 miles x 52 fill-ups (average) per year = 789.36 miles 789.36 miles x 3.33 gallon (average price for 91 octane fuel) = $2,628.56 saved
