Once I get my set I will do a write up on the install when Im able to actually do it.. I will also report on how they break in with periodic oil changes and drain plug magnet inspections for shavings and what not... Should be a PITA but a necessary evil for long term durability and confidence in the gear set. I plan on driving my rig ALOT as it is our camping and exploring rig!

@OTRAMM just installed both sets for me in a spare transfer case I picked up with low miles. If he sees this maybe he can provide feedback on the install. The transfer case won't be installed until next week and I don't know when I'll pull the trigger on the 315s, maybe not until the Spring but we'll see. I might not be able to stand waiting.

I received my gear set a couple weeks ago. but it will be a while before I can install them. Probably going to be a winter project with a spring install.. 31/34 tooth gears for a reduction of high range.
Good looking gear set!

I believe @orangefj45 is the current distributor of these. As for strength, they should be cut by the same Japanese supplier who does the OEM gears, if I remember correctly.

Absolutely not!!!!
That would increase the freeway RPMs.
The OP should either switch to 3.70s ( which is a unicorn in 80s ), or run the 10% Terrain Tamer OD gears or go to larger tires.

We have the high range UD and OD gear sets in stock as well as the 3.1:1 low range gears.
Strength isn't a concern; these gears are made by SeaMaster, who has been the OEM gear & shaft supplier for Toyota for decades ....
Feel free to call or message me anytime.

3.70 in your diffs, bigger tires or 10% od in your Tcase. Those are your only options.

I did. Been running them for a couple months now with 285s, will get 315s in the spring. I've had no problems with them at all, no weird noises or anything. I'll do a drain and fill on the transfer case once temps rise a bit here locally and see if there's anything no bueno there.
265/70/16 tires are smaller than stock, at least here in the USA. 2600 to 2200 rpm is close to 20%. I think you need to get 315/75/16 tires to get the gearing where you want it.

I ran my GPS and scan gauge this morning on my way to work and on worn down 285/75/16 Goodyear MTRs I registered 2150 RPM at 60 MPH on a fairly flat section of road. I don't actually know what this was on the stock gears so if someone could do the same I'd be interested to know the real world RPM difference.
I can make a 60mph pass in the morning with the 94 and post up the numbers.

I ran it up to 70 today and it was right at 2500 RPM.
