I'm wanting a 12v fridge freezer if anyone see ones for sale locally.

And tonight we got the lift installed and bumper on. My team mate who lives in Layton came up with his sons to give me a hand. And then we watched the Weber State vs Utah State hockey game. Which was a great game.

Let us know how it goes. Thinking about going 5.13 in the new year.

With 37s and 5.13 it's about the same as just driving in 7th.

So how do you like your KM3s? I am going to be putting 37s on and debating between KO2, KM3, and Patagonias.

So far I love them.
Only about 300 miles on them but I've driven to salt lake and back twice and they ride great at 80. Can't hear them on the road over the wind so reasonably quite.

My only complaint about KO2s is the size. They're lightweight because they're usually an inch smaller than every other tire in the same class. I loved them on my JK though. For the JT I went with Nitto Ridge Grapplers and I'm very happy with them.

No one makes a bad tire in the segment. Get the best deal you can is my suggestion. All reviews are going to be pretty subjective.

I am going to have to kindly disagree Oscar.
When you are spending a large chunk of money you should have accurate data to qualify your decision.
Below is the raw data and as you can see, there is a ~111 rpm difference in 4.88s and 5.13s at 70 mph. This is hardly noticeable and does not support the 7th gear theory in any way. The difference in the two gears is small but is an option.
My personal choice was 5.13s. This was based on our high altitude environment and simply a choice I made. 4.88s would have been my choice if I lived in a lower elevation state but that is not where I drive. Can't go wrong either way.
JMHO!!!

Something is wrong with your math.

If you look at the chart above comparing 4.10 (left) and 5.13 (right) you'll see in the last segment it shows rpm at given road speeds. Both with 37s

The difference between the 5.13s in 8th and the 4.10s in 7th is less 5rpms. I stand by my statement.

Actually I read it all again. Your using factory tire size with the 4.10s. to compare. Can't do that and have it make sense. Changing two variables at the same time dilutes the data. My statement was about 37s and 5.13 in 8th being the same as 37s and 4.10 in 7th. If he wanted to see how 37s / 5.13 would run just manually shift it into 7th. Which coincidencently is where mine sits most the time with 37s. I wanted 8th back is the only reason I'm regearing and if I had gone 5.13 it would have been the same as just leaving it in 7th IMO.

Another thing to consider when looking at gears is the numerically higher the number the smaller the pinion will be. Now the JL/JT ring and pinion is redesigned for more contact between the two. Deeper cut teeth that morare longer and more curved should equal more strength. But that doesn change the fact that going from a 4.10 to a 5.13 shrinks the pinion gear substantially. Which the graphics below I hope illustrates. My experience with racing jeeps and rock crawling over the years has shown me that 5.13 in a Dana 44 is the weak point. I can count at least 5 times where 5.13 pinion shelled a tooth in a Dana 44 and shredded the ring with it. I have never had 4.56 or 4.88 shred teeth. Strictly my opinion if I needed 5.13 or deeper gears it wouldn't be in a Dana 44. The 14 bolt or Dana 60/80 have the room for stronger gears in that size.

I'm glad you are happy with them and honestly given the redesigned R/P it's probably fine. Too many times pulling diff covers off on the trail for me to run that gear set.
