What rear end?

[MegaTruck]

Hmm, this whole thing makes me wonder if I can get my rear end regeared.  My hemi gets me about 25 mpg highway, maybe 26.  If I could get something in the high 3s or low 4s in the rear I would probably net a few more mpg.  Has anyone heard of the rear in an LX car being regeared?

I think it would require more than just gearing on your part.  With the trucks they already have a couple models (srt, powerwagon) that come with a much taller gear ratio.  You would probably need to upgrade your driveshaft and rear axle to handle the extra torque from the regear.  I don't think it's as popular as would seem.

You can't just swap the powerwagon or srt differentials in though so I doubt you could do that with an LX car too.  The problem you'll have is finding a gear that'll fit into the differential that you have.

MT, the differential wouldn't matter as long as it's big enough.  The swap would be a lot of work but very doable, just need the parts.  A lot more expensive than on a jeep or a truck though.

The question would be if Chrysler already makes different rear ends for the charger.  If they do, then he could just swap it out, especially if it's the deeper gear that he wants.  But I don't think many people do this since I've never heard of it done.

I don't understand why you guys always want to modify your vehicles.  It's expensive and makes them hard to repair.  Just save your money for a new vehicle.
