Gear ratio

Have a 03 Frontier, 4 door, supercharged with lousy gas mileage (9 / 10 MPG). What gear ratios are in the rear end and were there more than one option. Vin decoder don't seem to tell me the ratio.

TIA Al

Check the plate on the door jam. There should be an axle code there, something like HG43 which would mean H233B axle and 4.3 ratio.

If its the supercharged truck then its probably 4.6 or 4.9. If you find a non supercharged 5sp they have the 4.3's.
The code you want is on the firewall, engin side.

the Supercharged frontiers I have SEEN have 4.3x gears while all the supercharged xterras i have seen have 4.6x or lower.. the door jamb will tell the truth
