I finally got my hi/lo case installed and tested it today . All I can say is wow. My car is on 32” tires with 45/15 tubeworks gears. The car crawls like my Jeep with 4to 1 low range . Top speed at 10k rpms in 5th is about 27mph. Definitely makes this sxs a complete car now. I maybe trying 35” tires soon just for the mountain trails and maybe the rubicon trail. It goes so slow in low I don’t think you could ever break an axle .

Had the chance to see his rig in action yesterday. He was moving so slow and steady through a gnarly up hill rocky section. I would never attempt in a stock rig.

Really was impressive!

It is a little louder in high range but when your on the gas it’s not noticeable. In low range it is way quieter then stock . Almost no transmission noise at all.

has anyone installed one with just the 2019+ stock gearing?
If I ever have to pull the transmission back out , I will swap to the 2019 middle gear to drop my rpms while cruising . Basically drop from 15% to 7%

Big tires and low gears make for a lot of stress on the axels.
That said, I loved the 4:1 on my FJ40 and would love it on my YXZ.

Honestly it turns so slow and these things are so lite compared to a Jeep or an fJ I don’t think it’s gonna be a problem. I am running summer brothers 300m axles thought.

Wow! That is so cool. 5k isn’t bad considering how much fun it would be to see the looks on everyone’s face when you crawl like that 😂. How will the clutch hold up with this mod?

The clutch is actually not a problem. I thought it would be hard on it but it’s not one bit .
