    Will a windshield mounted light bar hinder my jeeps performance?

    Hey everybody, Jeep noob here.
    I'm about to install an AEV 2.5 in lift onto my 2013 JK Sport.
    I also want to install a windshield mounted light bar (purely for aesthetics) but I've heard this can seriously hinder my Jeeps performance. I'll be running 35in AT tires with a stock 3.21 gear ratio.
    Also this will be a dual purpose jeep.
    Will this affect my driving?
    Thanks

    I'm not sure if it would hurt your performance. But they do make noise going down the road they whistle but that can be corrected I just fixed mine

    they lower your gas mileage and add a ton of wind noise.
    no more jeeps at this time. next time it will be a cj with a v8

    your tire size will screw things up first 35's with the stock gear ratio will chew up all your torque and adding that light bar to it will make it worse, You need to regear that rig for the tires first, then the light bar will be negligible

    ^^^ what he said, I'll add you'll see a drop in gas mileage once you level it and add big tires, not to mention the gutless feel. Light bars look cool dude but I wouldn't own one unless I needed it. Put the money in an IRA.

    The LED light bars don't stick up as high so you may consider those. I doubt the mileage decrease would be that much. They already get terrible mileage anyway.

    it will be a noticeable drop. we took it off ours after 2 or 3 days because of how much noise and gas mileage loss. why go into single digit gas mileage just because you want your jeep to look like everyone else's jeep

    I had no idea they were that bad on the mileage. I prefer just a couple spots mounted at the base of the windshield myself.

    I lost 1-2 mpg posting my KC's there.


    Also a guy I worked with won a light bar rack so he filled it with 7 in light. That lasted 2 months doe to the mph loss.

    Not to mention the glare from the lights onto your hood can bleach out your vision at night, that's why I keep the lights on the stinger bumper on 'BB'
    Quick fixes are so named for how long they stay fixed.
    If you run out of gas, no matter which way you decide to push, the closest gas station will always be uphill and in the other direction. Corollary: The likelihood of running out increases when all of the nearby gas stations are closed.
    The parts shop that stocks part for Skylab II will not have parts for our year/model of Jeep.
    We cannot accurately judge the trajectory of a speeding critter (cat, dog, sasquatch).
