It is mostly a daily driver. Not much highway. When I am doing about 50mph the rpms go from 1500 to 2000 and then back to 1500 about every 1/4 mile are so. Just worried about wear and tear on the engine and tranny. Thanks for the help.

you have an auto, get the 5:13's I've had them in mine for 47K miles now and anything less would be a waste of money IMO

I have a 6 sp with 4.10's and 35's, when I put my 35's on I lost some power. When I use my ac or going up hills ,I have No power. I will be going to 5.13's because I plan on 37's soon. Just turned over 28,000 miles

I have 35's (for the next couple of days anyway) and i have 5:13's. I think they work pretty good. Dont expect bigger gears to help out your fuel economy though, it didnt for me.

As they shouldnt...you sacrifice economy for power....if you want fuel econ, go with 4.10s at the expense of any power. My 4.10s are god aweful with my 35x12.50s, but they work until I can afford to regear...been running this way for about 9 months now with a lot of miles. 5.13 is what I'll be installing.

I just finished regearing from 3:21's to 4:88's with a 2-door, 6-speed. I love them. I do run around 3000 rpm at 70-75 mph, but my freeway traveling is limited. This is with the 32X 10.5 M/T's that my rig cam with. I am going to upgrade to 35's, so I believe this will be perfect with them...
