    2018 TRD Off Road 4Runner
    Hello,
    I recently purchased a 2018 4Runner Trd Off road and currently running stock suspension and tires. I found a pretty good deal on a newer set of KO2 tires (Lt315 70r17) and was wondering
    what changes I would need to make to accommodate this bigger tires?
    Thanks for the help!

    Lots of things. That’s a 34.3” in tire. You’ll need a lift, UCA’s, a grinder to cut the cab mount, razor knife and heat gun to cut or move the fender liner and front bumper plastic

    Yeah, those are rather lrgentires for what you have. Gears would also be a recommendation to push those tires.

    I have 285/70/R17’s on mine with a OME lift that got me 3” of lift. I haven’t done the cab mount chop or went with UCA’s and don’t seem to have any rub issues that I’ve noticed

    Interesting, so you just installed the 3" coil overs then and ran the stock shocks in them?

    No, full OME suspension. Nitrocharger shocks and OME cool springs with OE top hat and trim packer and in the rear NItrocharger shocks and OME coils

    Cab mount chop, fenders cut, mud flaps removed, front bumper or you'll need to cut that too, 2.5-3" lift. You can put a body lift on if you really don't want to cut your fenders up. Rear bumper for clearance or you'll probably have to cut that as well. Hammer in the pinch weld. That's pretty much what I had to do on my 4th gen (I already had both bumpers though) and I didn't do the body lift. I had to cut about 2" off my front fender. I have some cutting to do in the rear still too. My tires are a 34.9 though so it's a bit closer to a 35.

    So you didn't need UCA's at all? Guess they wouldn't hurt though?
