I was wondering if people wit 4x2 are really getting better gas milage. I understand when you buy a truck you might as well exspect to pay for gas. That is not a problem. I was just wondering how much better 4x2 were actually getting.
I am unsure about the gassers. . .however I do know with the diesels the 2wd trucks usualy get about 2-3mpg better than the 4wd guys. . .on average now.
the IFS of the 1500 is just like the 2/3500 solid axel in that it is a live axel and spinning at all times. the vehicle is having to 'push' that axel which lowers fuel economy. I know there are some kits out there to unlock the front hubs and people have said they see an increase in fuel mileage.
I had a 4x4 1500 hemi with mds, my friend had a 05 2wd hemi no mds, both sbqc. he had 20's I had 17's, he still got a little better mileage then I did on a trip to los angeles from phoenix following each other.
me n myhomie both have the same truck hemi and all and before i modified mine and he wreck his, i was getting 1.4 mpg better than he was. im a 4X2 and he was a 4X4. after moddification i was getting even better than that if i went the speed limit
