So i been reading and i have the st model ram, which i hear is the 3.21 gears i think, how would i go about upgrading? and installation... thanks dudes

 

your a 4x4 so u would need to do both axles. everything done would prob be around 1300-1600

 

^^^ What he said, BUT, if those are the gears you truley have, it will be the best money you'll ever spend!

 

ok sweet thats def. in the future mods, so i saw abunch of different ones listed, which would be the best?

 

sort of on the same topic here i want to change my gears as well i want to put in 392 instead of my 355. i found a front diff but the rear one the axel snapped by the seal is it possible to use my axels and just change out the guts inside my diff or do i need the whole set up.

 

With the 6 speed trans and slightly oversized tires, I think your truck is a great candidate for 4.10 gears.

Guys with automatic transmissions and tall overdrives can offset 4.56's on the highway.

Do an experiment - drive around for a while without using 6th. 5th with 3.21's gives an overall ratio of 3.21:1, which is almost the same as being in 6th with 4.10's (0.79*4.10 = 3.23:1)

I think you will find that above 65 MPH you will be reaching for 6th to get the engine to calm down. Remember that you won't have that choice with 4.10's, but the truck will pull harder in all gears. That's the tradeoff.

For my Dakota, with smaller wheels and less weight to hoof around, I'm pretty sure I want 3.92's.

 

ur right, i just ran my truck in 5th going down 64 comin to work at 70 and it need to shift to 6th, it weas running around 2800 rpms as the 6th gear runs about 2000 rpms at 65, so dont change it? i wont be pulling anything, but again the tires will be heaveir
