5.71 gears with 33 12.5
hey ive searched on here and have found no definite answer. i have a 3.0 5 speed running 33 x 12.50 pro comps. a guy i know has a third member with 5.71 gears adn a lock rite locker he will sell me. will this be better or worse than stock gears? right now i can barely go 55 and forget about hills. i just crawl up them.

5.71's and 33's are going to be a tad tall. I'm running 285's (33.4's) and 5.29's and my rpms at 80mph are just under 3500.
Buy it and try to source a front end to match. Then install them and run it.... and then go with some 35's and have a freaking blast!!

400 bones is a good price, but you may waste 400 when you find it too frustrating to find another third with matching gears. And slow down, speedracer! Those gears are a bit tall for 33's, as others may have said.

5.71 is too low for 33's with 5 spd. 4.88 is what you want. Look for Auto stock with 31's...they came with 4.88.
Having said that, the 4.88 ring and pinion can not be use with Detroit locker if I remember correctly.
Yes, You do need to change both diff. or no 4wd.
btw, the terminology for too tall is actually lower number ratio. low is the description for higher number ratio. Ex. 4.88 is taller than 5.71 and lower than 4.10. ...

5.71's are horrible gears. the pinion is way too small to be strong. if your going to romp on them youll probably braek them. if it were me and wanting low gears i would look for some, 5.29's.

If I had the choice again and drove the hwy less, I'd have 5.29s with tall 33s (or find some 34s) instead of 4.88s. I loved the extra torque of having 4.88s with 31" tires, especially with single t-case offroad. Plus, the next natural progression is to upgrade from 33s to 35s...

x2 if your going to be rockcrawling the thing i suggest 5.29s as the highest gears.

Everyone has their person opinion on what will break what.
Personally, I won't go over 4.88's.
Check this website, which will give you a starting point for your RPM's:

i went form stock gears to 4.88s with 31 inch tires and they were great ..felt better than stock...with more mods(4.7.1 t-case gears) i wanted more low gearing at the axles....i installed yukon 5.29s and got a set of 33-12.50-15 bfg muds for free(1/4 tread left) and tried them out......everything worked great......i then ended up buying a set of 36-12.50-15 super swamps.....the 5.29s still worked great......i dont drive the runner on the hwy much so im not sure where im at as far as top end but ive heard nothing good about 5.71s...
