That depends on your tire size.

 

Plenum, cap, rotor, wires, plugs, pre cat 02, a good air filter and the correct tire size/ pressure are about the only things already listed that I know will help, about the only other thing I know of is a electric radiator fan.

Get a throttle body spacer.. better yet get 2 of them... That will gain about 5mpg...

After that make sure it is in tip top shape.. Complete tuneup.. Plugs,wires,cap and rotor.. Fix the plenum. Do the timing chain.. Do e-fans.. If you are running stock size tires dont worry about gears.. Maybe even get an SCT tuner.. Install an air/fuel gauge and learn how to use it.. That will get you the best MPG you will get out of these trucks.

 

Uuuummmmmm.....DONT get the throttle body spacer. He was just joking. (In case you didnt know)

 

Awee come on man... Have some fun lol

 

So you WEREN'T joking? Or were you? Or am I? Or am I not?

 

Well I personally run 4 throttle body spacers... And I have been on the same 9 gallons of gas for the last 5 months... SO am I joking or is this some type of sick joke??

 

tje tires are 285/75/16 and they came from the guy i bought it from like that. i would love suggestions on new tires too. lol

 

I like that size. Any idea what gears you have in there at the moment? You can get a build sheet from chrysler, link in DIY section, or, should be on a plate/tag somewhere on the truck as well..... (glovebox? under the hood? on the rear diff?)

Those are basically 33" tires. 4.10's work rather well with those. (close to stock RPM/MPH relationship) Gears aren't cheap, but, neither are tires. Probably came with 245/75/16's from the factory.
