    • 4130 chromoly tubular upper control arms are 100% bolt on and hand crafted in the U.S.A.

    • Custom profile upper and lower hi-misalignment spacers maximize droop wheel travel and are machined from heat treated 17-4 stainless steel. The lower hi-misalignment spacer registers into the slug adapter for maximum strength.
    • Upper control arms combined with extended length coil over shocks will allow for up to 1″ of additional wheel travel.
    • Urethane bushings reduce bushing deflection compared to stock rubber bushings.
    • Control arm pivots include zerk fittings to grease the urethane bushings & inner sleeves without disassembly.
    • 2 stage powder coat process includes a durable clear coat to provide a long lasting finish.
    • Complete grade 8 hardware kit is included.

Tire Info:

Q. What size tires can I run on stock wheels with the 3″ kit?
We have not tested every wheel/tire size on these trucks, but 265/70/17 tires will fit the 4Runner on stock wheels.

Q. What size tires can I run on a 17×8″ wheel?
With 4″ or 4.5″ back spacing we have several trucks running 285/70/17 tires, but they may rub on the front depending on wheel width, and back spacing. We do not guarantee any tire/ wheel fitment and recommend you have your tire dealer install and “test fit” any wheel tire combination you are considering

        A You would be fine with the regular. If you go HD, you'll probably get a little extra lift out of them which will in turn make it look like your rear end is much higher than the front unless you adjust the preload on the coilovers. If you planned on putting on an aftermarket bumper, then I would consider the HD springs. That is unless of course you want the extra lift. You'll likely get close to 3" out of those as opposed to 2" with the regular.

        A The rear will sit a little higher than the front but when you have gear, it will sag and will be more level. If you really want to level it, you can adjust the preload of the coilovers increasing their ride height or you could add a shim on top of them. If you add a shim, you'll want extended bolts too. Adjusting the ride height too high may cause a rougher ride.

        A Yes but such coilovers need to be custom built it will take more than 4 weeks

        A There is a small spacer in the shock shaft, that when removed, gives you .25" more travel at the shock, which equates to 1/2" at the wheel. This is per Jason Gonzalez, lead sales at King Shocks.
