It is a worthwhile exercise
to sit down and calculate
how much of an MPG increase it would take
to pay for that differential work.

It is also worthwhile to consider
that the 4.56 diff gears will 'mark' your truck
as one that has been driven hard or abused
and to most knowledgeable buyers (especially dealership employees)
will mean they won't pay as much
for a "rode hard and put up wet"
pickup that may soon break down on them.

 

well since your truck alredy has a 5 in syspention lift, 2 or 3 in body lift (i dont rember what one) and 37in tires, i think its alredy marked, atleast if you were to ever trade it in it wouldent be gutless lol, desides your not planning to get rid of it anytime soon lol

 

What gears would you all go with, 4.56 or 4.88? Im thinkin 4.88 would be better.

Think i'll eventually do it, just gotta save up for awhile, and try to get some overtime.

 

do you do lots of highway miles or city miles, pull anything, go offroading?

 

LOL...sorry offreading ? nudie mag ? LOL.... im going with 69 gear...lol... im going with a 4.56 little more TQ....

 

I play in the mud, or at the dunesmaybe oncea month, its definately not a show truck.

I drive 40 miles Monday through Friday for work on highway, and another 60 miles every 2 weeks on highway, but other then that its mostly city driving.

Not trying to insult youwhen I say this, just want to learn the most I can, but what does it matter on how often its highway, city, or 4x4ing when choosing gears?

 

If you need the truck once a month for recreation
and drive it on a daily commute
consider buying two floor jacks
and a second set of 'street tires' chosen for low rolling resistance and good stopping
and use that tire set during the week.

Tires wear out by the mile
so buying a second set just means your two sets will last longer.

The big off road tires cost a lot too
and it does not make sense to wear their soft rubber out early in street duty.

With two floor jacks to lift both ends of the truck at once
you can change wheels surprisingly quickly.

 

well id you spend a lot of time off road your going to want a higher ratio to give you a little extra torque....however with the amount your driving id say the 4.56

HankL's idea isnent half bad itherin the long run its cheper than regearing..however you do loose that "offroad look" when driving in town on doughnuts

padodgeramwell you never know when a guy is gonna wanna pull out a good book....maby some harry potter to go lol

 

Its a heavy truck with the aerodynamics of a brick. You want gas mileage, buy a Civic. LOL
