I literally just placed an order for that very setup and a couple of other items this morning!
They will be shipping today! Thanks again!

It is there but no where near the noise what my Pro Comp xtreme mud terrains make and they are fairly quiet. Also not a nearly as loud as cutting off the exhaust resonator when I added my 4x4 labs bumper. Now, add these three things together, plus the wind noise from the snorkel, and it gets a bit noisy at 80 MPH. That said, I didn't set this up to be a luxoliner either. Eventually I will have someone mock up a new resonator and use dynomat in the rig but that is down on my list.Fantastic, I'm very excited to hear this! How is your gear noise?
Here are my most recent plans for my '71 FJ40 build:
'76 2F; H41 from an '84 HJ47; split transfer case with drum parking brake from an '85 BJ45; 4.11 course spline differentials; BFG LT235/85R16 ATs on 70-Series wheels. 4th gear ratio (using BFG published tire diameter) at 70 mph (as fast as I'd ever plan to drive it) is ~3,147 rpm, which is a little high. Crawl ratio in 1st gear, low range is ~39.0:1.
Alternative 1:
Same as above but with 3:1 Sumo gears in the transfer case and 3.70 fine spline differentials. 4th gear ratio (using BFG published tire diameter) at 70 mph (as fast as I'd ever plan to drive it) is ~2,832 rpm, which is just right. Crawl ratio in 1st gear, low range is ~53.8:1.
Benefits of springing for the Sumo gears (I already have a spare set of FJ60 fine spline 3.70 differentials with the earlier, correct driveshaft bolt pattern):
Lower (better) highway rpms, lower (significantly better) crawl ratio, and somewhat stronger pinions.
Anything I haven't considered?
The Sumo gear set arrived in the mail earlier this week. I'm out of town so haven't opened the package yet.Sorry, I never saw this reply until today. Did we chat on the phone about this?
I NEED to to this!
Tell Sully to zip his fly before posing for the camera next time...
Do transfer case gears have a break in period like Diff gears do?
Has anyone done this in their 100 series that can chime in on their satisfaction of the underdrive and low range gear reduction set for their t case? Also curious what the total cost ends up being after new seals oil etc.
Technically, I think YotaMasters (and maybe Marlin Crawler?) keep stock of the low range gears (Trail Gear version) for 80 and 100 series and do installs at their shop, but they do not carry the underdrive or overdrive gears that you guys have or the Sumo version low range gears. I'm not aware of anyone in the US that carries the UD/OD gear sets, Sumo low range gears, or complete t-case rebuild kits for 80/100 series other than youIn fact I don't know of anyone else in the US offering the conversion parts to put the gears in the 100?

@cruiseroutfit So what is the total cost to have the under drive and low range gear set installed?Sorry, I was referring to the UD/OD High Range kits. To my knowledge we are the only ones offering and fitting those in 100/470's. Definitely some other great folks doing the low range gears too.
