Tested build at Holly Oaks....

This is where the reality of my 35's on stock gearing really started to be obvious. First of all, I had zero pep in the jeep in 4 high. Just zero power. It wasn't fun to try to drive fast if that makes sense.

I also had a horrible experience on this log obstacle. The logs were difficult to get thru. 4 Low was way to fast to crawl thru. I ended up riding the clutch to slow things down. I burnt the clutch and at one point got a warning on the dash that I needed to let the clutch cool down. You can see in the video, smoke bursting from my clutch at one point.

Next project... Rubicon Transfer Case...

Looking at crawl ratios...

Transmission first gear: 5.13 to 1
Transfer case Low range 2.72 to 1
Differential: 3.45 to 1

5.13 x 2.72 x 3.45 = 48.14

This is my current Ratio: 48.14

If I just replace the T-Case the 2.72 turns into a 4.0:
5.13 *4.0 * 3.45 =70.7

Rubicon Transfer Case Part numbers:
Auto transfer case part number: 68240441AA
Manual transfer case part number: 68321888AA

The difference was amazing! 48 to 71 was really useful.

Next up. Drummond Island.

Learned a few things.

4 Low is Great. I should spend most of my drive time in 2 hi or 4 low. 4-high is just weak. Check out the video. Great week. Jeep did amazing. With the manual, you have to pick your line and go. Letting off of the drivetrain by releasing the clutch is not the right move.

I do wish I had a lower crawl ratio.

Felt like the tailgate was stressed with the spare tire relocation bracket and the 35" tire. Added this Red Rock reinforcement. I think its been helping. The 35" tire / wheel is heavy for sure.

Also, I wired in a clutch bypass switch. This works in 4low only. If I push this button, it will start the jeep in gear. The idea being in a location I want the jeep to move forward with out the clutch.
