    Has anyone ran just a rear sway bar?
    I have a good bit of body roll, I didn’t really notice it at first coming from a loosey goosey xterra but since it’s been pointed out to me it’s pretty bad.
    I removed my front sway bar when I did my suspension, one of the nut plates in the frame broke off so that one isn’t very easy to put back on, nore do I really want to put it back on.
    I've seen people run rear only sway bars on ifs rigs and actually gain flex when crossed up and wondering if anyone has experience on our trucks both on road and off with only a rear sway bar

    Another alternative is if you install rear sumo springs, they behave like a rear sway bar and have the added benefit of load support.

    I’m running an icon pack so I’ve got decent capacity and it still rides really nice, I’ve heard the sumo is rather harsh unloaded, I’ll go bags with cradles if I want more capacity.
    Also they definitely don’t behave like a sway bar, they just make each side stiffer, they don’t tie the 2 together

    Ive tried it with stock height up front. It was downright dangerous on the freeway.

    i ran icons with no sway bars, that was fine as they had higher, linear spring rate and raised a arm angles help too. Stock springs no way jose

    That’s what I’m currently on, I like it but just looking for a little better cornering on road but maintain the oversteer before understeer offroad

    I have both the trd front and trd rear away on my stock height 2wd. Ive experimented disconnecting both, the rear sway inhibits more flex than the front when isolated.

    Im considering removing the rear sway if I can’t find a way to loosen it just a little, maybe mounting it on the rear of the axle…

    you can get that nut in there, mine was broke too, an open end wrench fits in there to hold it

    how is your front tire pressure? Maybe add 5 psi and see how it feels in corners

    Why not just try it out? Considering the appreciable difference the rear bar makes for most, it should be noticeable. Maybe not optimal, IMO, to only run the rear, but not worse than no sway bars at all I wouldn’t think. I had an old bronco years ago that I snapped a front sway bar link without knowing. It had sway bars front and rear. One day I decided to remove the rear for “better off-roading” and it was loosey goosey in the corners. I ended up welding up some new end links for the front and replacing the bushing all the way around and it handled like a sports car! Well, a bloated, chubby, underpowered, anemic, but totally fun to chuck in the corners kind of race car. Definitely better than my friends old mustang. Or was it a pinto? I dunno. I think they were actually the same thing at one point…

    I put a Toytec kit on a month or two ago and left the front bar off, rides nice! A bit smoother over bumps but more lean in the corners. By no means unstable. I do have higher rate coils over stock. For now, the front bar will stay in my shop.

    C-channel frame flexes a lot, with or without sway bar. Also the way the rear sway bar attaches to the frame, it reduces the effect of the sway bar.

    Buy a welder, weld that nut plate back ;)

    let me know if you end up doing it. I’m curious on the outcome. I run no swaybars and daily mine. I thought of the idea of just the rear only, but haven’t found any information on it. Love how plush the ride is, but wished I had a tad bit less body roll on corners.

    There is a lot less mass high up in the rear than the front so the impact is dramatically less. Controlling the sway of the engine for example makes a bigger impact

    There is a lot more mass in the front of the truck. I would think the front only would have a more significant effect.

    I have removed the front sway bar and installed rear sumo springs on two Gen2.5 Tundras with stock suspension, then another Tundra with a full suspension lift. Without the front sway bar on stock suspension the truck is very rolling in corners. With the sumo springs though the behavior was similar to stock in corners while still benefiting from no front sway bar (independent front suspension actually working) so bumps and pot holes are alot better. I would imagine a rear sway bar would be similar in reducing roll while benefiting from none in the front. Removing the front sway bar is mainly a positive offroad, whereas if I had a street only vehicle would not remove the front bar. With most full suspension lifts with no sway bars/sumo springs the ride is firm enough to not be needed, very little rolling is present.
