    Just got my Nitro's and LSD installed. TOTALLY DIFFERENT TRUCK :thumbsup:

    Had a Toyota Dealer do it. They broke the left front aluminum axel shaft trying to press out the bearing. Another reason I went with doing it there. Just in case something got fucked up.

    That LSD is killer. Nothing like chirping BOTH BACK WHEELS with little effort on the gas peddle:burnrubber:

    4.88’s is a must with 37’s!!! We need 5.13’s or 5.29’s!!! Still not stock on 4.88’s . Just keeping it real!!!

    In a reliable good shop what's a realistic price tag from going stock to 4.88 ratio switch?

    The guys that’ve had it done will be able to provide a better number, but for some reason $1300 for gears and $1000 for install seems to stick in my head.

    If I remember right, I think I paid $3200 installed for front, rear, and auburn LSD. Then another $100 for the break-in service after the first 500 miles.

    I’ve been on 38x13.50’s for a few months with stock 4.10’s, I’ve become used to the loss in power.

    Then I drove a stock 5.7 yesterday, and remembered how touchy the gas pedal is. It was like a tuned track car by comparison.

    I would definently go for the 4.88’s if I had the money for install, I’m not brave enough to attempt that DIY.

    I run 37x13.5's with Stock Gears. I am Dap tuned. Havent had one issue. Yes you notice a loss in power on the street. But the way I wheel, it doesnt make a difference off the dirt. Throwing into 4-hi or 4-lo in first, and then crawling with he 37s makes things feel like child's play.

    At some point I would like to re-gear but I do not have the $ to do so at this time. Maybe in the future when I go Mid-travel suspension or if the wife convinces me to go LT. Right now it is too much of a daily driver to warrant the $ spent. I know in time the rig will see more time in the dirt then it does on the road. Thats the goal, without changing how much I drive on the road now20181024_055007-1.jpg .

    I’ve never opened a google search that fast in my life. I didn’t believe what you said at first, since all I’ve ever seen for our trucks are 4.88. But I’ll be damned, there they are on the Nitro website. Not released until 03/19 but I’m glad they finally offer something steeper than 4.88’s.

    If I’m going to go through the trouble of re-gearing from 4.10’s, it makes more sense jumping all the way to 5.29’s vs 4.88’s. Thanks for sharing that! :thumbsup:

    Don’t do it. Go to a reputable shop it’ll be a better price.

    With 35s on mine I'm starting to believe that everyone who said stock gears are fine were referring to city/in-town driving. My times on the highway starts to ride like sh-t once I get about 65+. Truck wants to keep kicking out of overdrive on the slightest incline.

    I keep seeing that 4.88s will bring me back to stock like feel, what does going with the 5.29s do for you? Improved anything? Risks?

    Sometimes I feel like for some reason my truck is different than everyone else’s, it’s obviously not lol, but with 35s mine felt great. I’m currently running 40s with stock 4.30s and this bitch will roll down the interstate. I honestly believe 4.88s would be plenty, but when funds allow I’ll be going 5.29 only because I have future road trips planned and I would like to be able to use cruise control again.

    I respectfully disagree that our trucks need regearing for 35s, situation depending of course towing and hauling etc, but in your case 4.88s would suit your needs. 5.29 would be too low IMO. Older Toyota’s have a 5.71 option which is insanely badass, as far as risks I read an article on ring and pinion strength and studies showed that the difference was neglible, between 4.56-4.88-5.29 etc. There are a ton rock crawlers with steeper gear sets than anything our Tundras will ever see and have zero issues. It all comes down to the installer and making sure everything is in spec and tolerance.

    @15Yota even on highway with the 4.30's, no issue? Mine just want to stay in 5th... It'll go to 6th on very flat land, but slightest hill seems to put it back in 5th and it holds there until I slow down a little more, let it shift, then I can speed back up but it'll jump back to 5th at the next hill. And when I say hill, I mean little central Texas hills, not anything big.

    Maybe there's something else I can do? Pull the battery and let the computer reset? Retune for different shift points? I dunno, certainly open for options that don't involve dropping another 3-4k, but I drive highways way too much to not address this.

    As for the 5.29, I only ask because right now I'm not really hauling, but I do have a travel trailer in my short term plans so wasn't sure if I should go ahead and get what I can since I'm paying for the labor anyways.

    Mine drops down like you describe as well, but being as my speedometer is off by almost 10mph, I cruise at what I see as 60mph and it keeps up just fine. I have “raced” a few other lifted Tundras and I know they have to be surprised when I stay neck and neck with them LMAO. I really should stop doing that though. 90% of my driving is in town so it’s not a necessity at the moment.

    If you plan on pulling an RV then yes absolutely regear as soon as possible. How often you plan on pulling it would be my first question. 5.29 may not be out of the question.

    I wouldn’t mess with the transmission shift points, that’s asking for trouble.

    Does the speedometer come into play on our transmissions shift points? So could the fact that your speedometer is so far off be part of the cause of hunting for gears? Obviously it’s not all of it, but I’m wondering if it could be part of it. 10 mph is a-lot
