    That will be interesting! You will probably be the only person to try it, so it's generous of you to share the data/experience. Have you worked the numbers to see what 6th/70mph rpms will be?

    Ya I have ran a few calculations and assuming my stock tires are 31” 6th gear at 70mph should be about 2325 rpms.

    So It should have close to the same rpms as stock gearing in 5th

    09/16/18 Update
    Just getting in a quick post for people but will provide more updates later.

    Gears are in and truck is home. Big thanks to @thefatkid for doing the gears for me. Super great guy and an absolute genius with Toyotas and off-roading. Thanks again Brian.

    Brian completed the initial heat cycle and I completed two more on the way home over a 55 mile trip home. The heat cycle is a common practice and a part of the break-in for the gears. With REM polishing, most if not all of the break-in is essentially already completed as most of the friction points have been polished out but as a best practice it's good to complete the heat cycles and the traditional break-in. With such a large investment, it would be a waste to have a mechanical issue so early before I get to really use them. Temps were around 140 if I recall correctly which were really good. Gears now have 70ish miles on them.

    So my initial thoughts!

    I drove the truck pretty conservatively as it was the first time and had a bit of a hike to get home. That being said the truck was surprisingly not over-geared. In fact the truck compensated for it rather easily, shifting early and quickly to get to the higher gears before cruising. The truck responds significantly better especially in the lower gears but I tried to take it easy on the way home and my experience with that is, the truck drove rather normal. Normal may not seem amazing but agin, I just went from 3.90 to 5.29 with a 31" tire. Most expectations are the truck would be screaming in rpms and top out at 65mph. Really the truck kept rpms low under 2500 for most of the drive. I think Brian summed it up pretty well "it drives different."

    That being said here are some data points and observations.

    The truck was in 4th by 30mph and anything higher cruised in 5th and 6th. I took Hwy 105 home which is curvy and hilly and the truck stayed in 6th at 55 pretty much the whole way home. Only occasionally dropping into 5th on a steep hill, the same hills the truck would previously run 3rd or 4th in. From a basic feeling of its driving it feels like the entire transmission gears were shifted down, meaning 6th gears feels like what 5th used to be, and 5th gear feels like what 4th used to be.

    Quick Notes on RPMs and MPGs, they are as close as I could get without getting too crazy on the accuracy but should be a solid enough data point to give people some information and perspective. I'll clean it up in an excel later. Note the huge RPM drop from 4th to 5th. Those overdrives gears going to work.

    1st Gear - 3.90 - 20mph - 3000rpm
    1st Gear - 5.29 - 20mph - 4200rpm

    3rd Gear - 3.90 - 45mph - 3000rpm
    3rd Gear - 5.29 - 45mph - 3800rpm

    4th Gear - 3.90 - 70mph - 3000rpm
    4th Gear - 5.29 - 70mph - 4100rpm

    5th Gear - 3.90 - 70mph - 2200rpm
    5th Gear - 5.29 - 70mph - 2900rpm

    6th Gear - 3.90 - 70mph - 1700rpm
    6th Gear - 5.29 - 70mph - 2400rpm

    3.90 Gears, stock tires, MPG:
    20.7, 18.6, 20.7, 21.2, 19.2, 18.6, 19.2 = 19.74 Average mpg over the last 7 tanks.

    5.29 Geas, stock tires, MPG:
    *Only 70 miles on gears and trip averaged 18.9 mpgs

    I'll continue to collect data on mpgs and rpms at speeds. From the initial drive the truck drives awesome, you will notice that it shifts quickly to 5th and spends most of the drive in 5th and 6th but again I drove conservatively so not sure how it will respond yet when I drive aggressively.

    I did notice my cruise control could not handle itself, on the hilly section of 105 the cruise control wanted to downshift to 4th on the climb then shift to 5th at the crest then 6th on the flat or downhill and repat over and over on each hill. So I turned cruise control off and just drove normally and the truck kept speed and gear the whole time in 6th so not sure why the cruise control was shift happy. I dont know on that one but will test more.

    It is a great review going from Stock to 5.29s, but his results are the same as what I had with going from Stock to 4.88s. I wish he had 4.88s prior so he could do a review between the two

    I thought he had 4.88s? I could be wrong?

    No. He had stock gears before that were slowly just losing ground with the more weight he added with his mods. I’m really hoping there will be someone that does have the 4.88s and does the conversion to 5.29s so we can get their review.

    What are you guys laying for labor to have the 5.29’s installed? Im doing my research and the gears about 1500 everywhere.

    Drove it to work today and the road only goes up to 45mph. My commute is only 3 miles so its a couple of hills and maybe 5 lights. Truck definitely has more pep and I barely have to press the gas to get it to move. Honestly the truck drives great and feels like it has a ton more power. It drives the way it should.

    I don't drive my truck a whole lot, but to be honest, I would be perfectly happy with 5.29s and stock tires. It feels fine so far and the AT compensates nicely but this is still the initial impression, maybe after 1000 miles and a few tank fill-ups I may change my mind. However, I don't think I would want 5.29s on stock tires if I had the MT, only because you would be shifting fast but I guess you could just skip gears, could probably start in 2nd and just jump to 4th then 5th. I dont know since I dont have an MT. Just my opinion, but I think these gears would work just fine for stock tires all the way up to 35s, but I'll find out more over the next couple of weeks waiting for the wheels to arrive.

    I wish I had 4.88s to compare but at this stage I am glad I went 5.29

    Yeah I wonder how much lower the RPM will be with 35s on. I have 33s now, but definitely will get the 5.29s when I go 35s.

    here are some photos of the speed and rpms while driving. I took these this last night and one this morning. I was only at 70 for maybe a mile or so on I-25 to not overstress the gears/oil.
