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 would think the gassers would have the same results.. lighter running gear, lower profile in the front.

I do know that the east coast CTD's get better mileage than the west coast CTD's [sm=boohoo.gif] lol

 

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.

 

The 4by is much heavier and has a lot more rotational mass. With all other things even, it will definetely get less mileage.

 

better mileage for sure...i average around 19-21 with mine

 

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
