or 3.21...... Got it off of my build sheet the other day at the dealer ship... Couldnt find it on the front frame rail, then realized its not a factory piece anymore.

 

His is a 4x4 though, so I assumed it would have at least 3.55.

 

mine is 4x4 too

 

Wow, my bad. I assumed from your sig pic that it was a 4x2 because it looks lower to the ground then mine, but it must just be that your sig looks stretched. Fooled my eyes.

3.21, 3.55 or 3.92 are the options then if it isn't an Off Road edition (or already been regeared by previous owner).

 

i think the superchips was way worth it , i had the death flash and it was a day and night diffrence when i put it on, or you can cure the death flash for free

WANT TO CURE THE “DEATH FLASH?
Do you have a 2000 or newer truck that no PCM is offered for or the dealer pulled 4 degrees of timing out of, with the DRBIII to keep your truck from having detonation or pre-ignition problems, and now the truck is a pig? Sluggish and generally will not spin the tires from a stoplight, even with a 360?
Then advance your timing.
Your timing is set initially by the crankshaft sensor and the distributor has the camshaft sensor in it to determine when the injectors fire relative to the amount of valve opening. So moving the distributor does not affect base timing. But moving the crankshaft sensor relative to it's current position does. The trick is this, and takes about one hour. This will work on any Dodge truck 92- to present except for the 4.7L or the V-10.
Remove the crankshaft sensor on the aft/passenger side of the block. It is held down by (2) 1/2" bolts and pulls out of the tranny bell housing when loose. There is a rubber grommet in the bell housing also, remove it. Now look at the sensor's bracket, notice the 2 bolt holes. Slot each hole 3/8" both ways, still giving the bolts something to hold onto. Then insert the sensor back into the bell housing, making sure you pulled out the rubber grommet. Thread the 2 bolts back in loose, then slide the sensor as far as it can, towards the oil filter, away from the intake. This will advance, moving it towards the intake in the same direction of crank rotation and will retard the base timing; do not do this unless your teenager is driving the truck. It will usually be limited by the bell housing how far you can move it. If you are really brave, grind the bell housing and fab a new adjustable bracket. This will add 3-4 degrees of timing across the whole board of advance tables, and cure the Death Flash problem in your Magnum. That'll be $5 please...just kidding!

this is one instance where i'm glad my truck is as old as it is lol.

 

I understand "no offense" but i got on here so i could learn more about my truck. To answer your question, i was up under my truck washing out mud the other day and there is a sticker around the rear axle that says 4.10 4x4 true lock.

 

hey i have a 2001 dodge ram 5.9L. i just got my super chip about 3 weeks ago and i wish i would have had it the day after i got the truck. it makes one hell of a diff! most people say the 87 oct mode is crap but ive been playing with it and to tell you its not to bad to me. my trucks setup it 3.55 gears with 35" tires and it rolls just fine. i picked up about 2.3 mpg in this mode wich brings my truck up to. 17.6 mpg (mainly highway driving) in the 91 plus mode i get about 1 mpg better but man can you tell a diff in the power it will spin my 35's with ease in that setting.

i got mine off ebay from a store call loopers speed shop out of AZ he still has it listed as the 3815. but when i got mine it was the 3865 wich is the new one. but he sells them for $299.99 with $10 shipping and only took me 4 days to get it.

 

Well, there ya are. If its not an Off Road, a previous owner must have done that for you. That was nice of him/her, because it costs a pretty penny to change the gears. $900-$1000 in labor (thats for both axles), not counting parts.

The Flashpaq will definitely help you out.

 

I appreciate everybody's imput and i think i am going to order the flashpaq tonight alog with my rear bumper..the 2 inch spacers for the front are on the way as well.
