I can’t seem to find anyone that makes taller gears for the 80 series, tons of shorter gears, basically I’m trying to lower my RPMs at highway speeds but can’t find any

I’m running a Duramax and a 4l80 transmission, at 75mph I’m sitting around 2500rpm which is high for the duramax, I have the power to move the land cruiser so I don’t need the rpm
Overdriver TC high range - assuming you still have the factory full-time (HF2A/HF2AV) transfer cases

I second this. Easy to do, and much easier to revert compared to axle or TC gears in case the effects are not as desired.

I’m already on 33s and don’t want to do more of a lift

Don't need a lift for 35s.
There is 3.73 ratio gear sets out there, the australian and JDM 80 series often had them from what I remember.

3.73 gears
with all the diesel swaps in here, has anyone regeared to 3.73's? seems like they've always been elusive for the 80s, but looks like marks4wd in aus has them...at least listed on their website... http://www.marks4wd.com/drive-line/diff-gears/toyota/dgland80.html

Edit: this was a group buy and page 2 on have install reports for future reference if any one is looking for more details on the gears. I'll be ordering a few sets from Marks4wd in Australia they are stock for some of the diesels over there from what i understand. we can bring the price...

This is perfect thank you
no lift needed for mall crawling on 35s. Just need to get over small speed bumps.....

Perhaps your aftermarket wheels have the wrong backspacing...
My 04 Duramax has 4:10 gears installed and 33's. Runs all over the country towing a trailer just fine. It puts it back to stock gearing. I am sure you are not going to hurt the engine but you do not weigh as much either. I would not be scared to just run it. I would be more afraid of blowing up the axles.
You have the wrong transmission, you 4L80 is not geared for your set up, you can get some 3.54 gears from Australia or the Sumo with the over drive gears, you really should have used the Allison
