    Looking at buying a 2013 double cab 4x4 with Icon 5” lift. Owner says it has original gears. Will the 3.73 gears and auto trans hold up for normal highway/town driving? I live in Tahoe 6000ft elevation, will this setup have enough power?
    What should I do to it to improve it. Re-gear?

    5:29’s should help.

    depends on wheels and tire sizes. At 6,000 ft nothing runs good.....:(

    You could also supercharge to help but sounds like it needs 4.56 or the above mentioned 5.29.

    I feel like the 4:56 would be to tall for the 5” lift and 35” tires 4:88’s maybe. 32-33” tires the 4:56 would be ok but I’d probably want the 4:88’s for 33-35” and 5:29’s for 35+. That’s if your goal is to get close to stock ratio.

    I’m picking up the new to me Tacoma tomorrow. Now I’ll have to decide if I should change the lift to a 3” or change the gear Ratio. I think the price will be similar although new wheels may add to the cost. IMG_0925.jpg

    Congrats. Depending on how it's lifted, you may not be able to go back down to a 3 inch lift.

    Took possession of the truck today. It rides and drives well. The tires are actually 32”. I’m gonna drive it a while before I decide how to improve it. Right now I’m thinking a set of 4:56 gears will probably get the results I want. I’ll be using the truck mostly on the highway going from my house to Tahoe over an 8000 ft pass several times a week. No high speeds but there will be snow.

    Love the Donner Pass! If those are 32" tires, then that almost has to be a 3," lift, yes? Ie, there's no additional differential drop brackets? Which also means that no crossmembers have been cut? This is a good thing. Anyway, you live in Tahoe? You could definitely benefit from a gear swap. I lived in Reno for a few years and was always up at Tahoe or so many other places around Northern California. Anyway, I ended up switching to 4.56 gears fairly quickly in my 10. Definitely helps in those hills. You might want to look at 4.88 gears, I think, not positive, you can run those. Pretty sure 5.29 is way too much for your final drive ratio though.

    I was just on the flume trail a couple months ago. I was actually wishing for lower gears in my 17 with 285's on it while I was there pulling a uhaul trailer. Haha 20180813_114245.jpeg

    It has an Ikon 5” lift. Yes the frame was modified and it had the drop
    Crossmember. It tracks perfectly so far. I got it for a really good price so I have room to spend if I need to.

    If you ever think you would consider running a 35" tire, maybe you should look into 5.29's. Only want to spend the $$$$ once!

    I thought I’d give an update on my tacoma. I love this new to me truck. I thought it might need an alignment so I took it to a local Tahoe tire shop. They said they couldn’t align the front end because it needed other work. All new shocks/coil overs, rack and pinion bushing kit, new UCA’s, and passenger side lower ball joint. Wow.
    Then I took it to a custom off road shop in Reno with the list of problems and asked the owner Nate to check the truck and come up with a to do list.
    He had two different tech’s go over the truck
    The only thing they could find was to recommend I change to a 17” wheel and tire combination.
    I currently have 305/55/20’s. I’m looking at going to a 285/70/17. The 20’s look good but they seem to wander and I think they are so big they rob horsepower.
    So I’m still trying to decide what to do with this Tacoma to get the best performance and drive ability.

    I wouldn't go back to the Tahoe Tire Shop that's for sure!

    Follow up on my truck.
    I changed from 20x12 inch wheels to 9x17 inch I went from 305/55/20 to 285/70/17 tires.
    What a positive improvement. Drives much better, tracks straight and feels like it has more power.
    Next I will work on coil overs and shocks.
    I like my truck now.
