How do you figure? I have 3.55's and it's still not long legged. My mustang has 2.73's. 3.92's have got to be better than 3.55's.

 

I run 4.10 and did not noticea major change in highway driving. The mileage change was minor and rpm changed by a couple hunred. The low end is much better and the trade off is well worth it. Your other option is a 3.92 but there isn't much difference from there to jumping up to 4.10.

 

What part #'s did you get? I looked at stuff for my 97 and it came out over $500.

 

where can i find 4.10's for mine i got a 2wd 98 dodge ram 5.2L single cab?????!!!!

 

Summit racing. I think I'll try 4.10's if they don't affect gas mileage and rpm's much.

 

I called them. i think they are running a special.

 

did anyone install the gears themselves i was thinking about doing them to my truck im only 2wd

 

I wish I was comfortable enough to change mine. It's freakin expensive and i don't know why.

 

It's not a simple swap. There are very precise measurements for backlash, and you need specific tools to take the correct measurements.

 

how much is it to have installed?how much would it be with a locker?
