Comments: Have yet to try them out as I am still putting the jeep back together but will let you know performance with the 4 banger when she is up and running! So far everything looks really good!

EDIT: Am very pleased with the gearset and can def. tell a difference from the 4.10 gears

Comments: Good gear ration for me. I have a 5 speed transmission, so fifth gear acts as an overdrive and I get pretty good gas mileage on road. Off road they are great for creeping through the gooy stuff

Pros Great gearing for 35-37" tires
Cons None
Recommended yes

Comments: I have been running 4.56 gears since i had 33's. They were a little bit high for 33's but faired better than my 3.07s were. With my 35's the gearing is awsome for crawling.

Pros It brought back lost power. Not having driven a 2.5 with stock gears and wheels I don't have a good comparison. It pulls hills better than it did though.
Cons Price maybe but gear swap is not something I wanted to try. Right now I don't have 5th gear so I've been driving in fourth. 3300 rpm @ 65mph isn't uncomfortable, I'm think I should have done 4.88 gears instead. 200 to 300 rpm more would work better I think.

Comments: Having driven my jeep for a bit on the freeways with 4.56 gears and 31's if I were to do it again I'd go 4.88's. 200 to 300 more rpm would be ok on the highway and a little extra pull on the lower speed would be good. I drive mine in 4th gear because 5th has a bad vibration (transmission related). Using 4th, 65mph at 3200 rpm is comfortable so 65mph at 3000 rpm in 5th with 4.88's would be find as well but with more hill pulling ability. My 2 cents.

Pros Performance improvement.
Cons Not as quiet as a Yukon.
Recommended yes

Comments: Not quite as quiet as a Yukon but for my front end it's not a big deal. I went with AlloyUSA's front 4.56 gear and I am happy with my choice. Don't get me wrong it is not loud by any means either so I expect you will be extremely happy going with these.

Pros with the 2.5 the 4.56 gearing is my lifeline, and off road 4LO is unstoppable
Cons sits in the Turdy5 rear
Recommended yes

Comments: the 4.56 gearing makes turning the 32's easy on road, and in 4LO great combination to keep me moving

Pros Highway and city driving are a pleasure on 33" tires
Cons None that I'm aware of.
Recommended yes

Comments: These gears actually came on the Jeep when I bought it so the price I listed is not relevant. However, my TJ runs beautifully with 33" tires on the freeway at 65-70mph all day.

Pros Custom made Dana 44 front with 4.56 gears and chrome moly axles with a u-joint knuckle conversion. It has held up very well. The only problem I had was that I broke a u-joint by not getting out of the right pedal when it started wheel hopping. So that was my fault.
Cons No cons. Maybe should have gone with 4:88 gears instead.
Recommended yes

Comments: I had this axle custom built because I made my own 3 link suspension for it.
