How do I tell which gears I have in my truck? I would like to find out so I can possibly go to a slightly lower gear.

 

Check the tag on the axle. If that isn't there, request a build sheet from chrysler, instructions to get one in the FAQ section. If you are impatient, jack up the rear of your truck, put it in neutral, block one tire, turn the other one half turn, and count the number of driveshaft revolutions. That's your gear ratio.

 

If your truck hasn't been messed with, you should also have build data on a label on the underside of the hood near the grille bracket. Mine still has it, but I know that some don't have the same convenience.

 

Mine has it, but it is faded to where you can't make out any of the printed text.

 

tell us more about the truck, year, 1500/2500, engine... it'll help us determine what ya got

 

See Signature

 

I would guess that you have 3.55 gears if I had to... thats the most common for the 1500s

 

or maybe 3.92 but i doubt it would have it

 

mine had a sticker in the glove box.


You could jack up the rear end, put it in neutral, mark the tire and drive shaft with chalk and spin the tire. Count how many times the drive shaft turns for each one rotation of the wheel. 3 1/2 turns is 3.55 gears, almost 4 is 3.92, just over 4 is 4.10, etc.

 

that wouldn't be a bad idear, but wouldn't it take a while to figure it out lol.
