Modded the Motobilt rear liners for better clearance and pulled a bumpstop from the front...2" front/rear now. Took it on a topless drive enjoyin the awesome weather..
I like the name. Great choice.After 2+ years, finally ordered hood decals from @pixeldecals to name the jeep. It's tough to think of a name that is unique and not too cheesy. Going with NOMAD in a solid red black lettering...I like to explore alot of different random wheelin spots and haven't seen this name on another jeep.
Also, planning to order gears this week based on staying on 37s with these rubi axles and 6 speed...drove on flat hwy yesterday at 75mph in 4th and 5th gear to get a feel for power and comfortable cruising rpm's.(6th gear isnt useable with 37s unless going downhill) On paper, 4.59 gearing with 37s is equivalent to 4.10 gearing with 33s...but that doesn't consider the extra rolling mass of 37s, approx 400lbs of added weight with steel bumpers/winch/skids and the additional drag created by lifting a jeep.
At 75mph, 4th gear with 4.10's was at 2800-2900rpm and is equivalent to being in 6th gear with 5.60 gearing. Had plenty of pep, but motor felt over revving and it would get tiring on the highway and mpg's would prob be around 10mpg.
At 75mph, 5th gear with 4.10's was at 2300rpm and is mathematically equivalent to being in 6th gear with 4.56 gearing. It held speed with cruise control and could also speed up slowly on flat ground, but motor felt weak and I had to downshift for inclines. I can see why people prefer 4.56 to run 35s.
4.88s @75mph, 6th would be running about 2450rpm.(150rpm higher than 4.56) According to a friend running JL 6 speed, 4.88s on 37s/beadlocks, it holds 75mph well on the HWY and the crawl ratio bumps up from 84:1(stock) to 100:1. He said it crawls noticeably better and will idle up steep obstacles.(He has done the Rubicon + 20+ other badge trails on 37s/4.88s) That would address the stalling issues that I've been having on steep obstacles.
5.13s @75mph, 6th would be running about 2600rpm. It obviously holds 75mph well on the HWY and the crawl ratio bumps up from 84:1(stock) to 105:1. You pickup 5% more low end power, but start taking an efficiency hit on the highway. The pinion teeth are also a little thinner/weaker than 4.88.
4.88 seems like a nice fit staying on 37s. It's a little stouter than stock to account for the added weight, crawls better, has a little thicker pinion teeth than 5.13 while not sacrificing HWY mileage. Thoughts/feedback are welcome..
Thanks...4.88s and 35s at Colorado elevations is prob similiar to 37s and 4.88 in Tennessee.I like the name. Great choice.
I also decided 4.88's would be deep enough for me as I'm set to stick with 35's... but it's good to know that I "could" go to 37's with that choice.
Thanks to all who have followed this build...it's's been a fun and educational ride over the last 2.5 years. Unfortunately, I was spending alot of time getting things fixed at dealers(10+ visits total) and had to have 2 offroad shops chase down frustrating death wobble and eventually replace the balljoints at 29k miles.(not cheap) Dealer service wasnt great and I was getting ready to dump more $ into regearing. With 4 kids, it got to the point where the jeep became a hassle and I didn't want to own it out of warranty...so I sold it.Going through your build was such a great read.
