    Can someone confirm if I must get extended links if I put a TRD Sway Bar on a 6" lift?

    I don't really want to go through the hassle of getting it cut/welded/painted.

    Thanks.

    No, it'll fit, you need no extended links, I have a 6" RC lift with RSB, fits fine

    TC long travel. Deaver 420 SU leaf packs.
    Fits w/o extended links like @ARamirez73 said. I think @1UPPER had some custom links made but not sure of his lift height or if it was absolutely necessary?

    Did you notice an improvement with your lift and the sway bar install?

    I’ve seen guys run the TRD swaybar on a lifted truck without extending the links. How affective it is compared to extended, I don’t know. If you haven’t purchased the TRD swaybar bar, look into hellwig sway bar since it’s adjustable. C519402E-D119-47AA-9BA7-64329510C4CC.jpg

    That looks like a good option, just can’t justify the price difference between that and the TRD sway bar. Looking at almost $250 extra.

    To help compensate a little bit rotate the U bolts that hold the sway bar to the rear end towards the back of the truck. 90°

    Rotate the bar so it sits higher on the axle housing. Extended links are only required if running leaf packs without blocks.

    My truck has a 3 inch lift in the rear and sits like it should. No extensions needed.

    There was only about $50 to $75 different between TRD and the Hellwig.

    On Amazon I can get the TRD for $330 Canadian. They have the hellwig for $600 CAD and summit racing has it for $350 USD.

    Where is the best place to buy hellwig?

    FWIW, extended links return the sway-bar's arms back to perpendicular to the axle travel. Without extending the links, the SB arms are angled, which decreases their effective length. This, in turn, increases their effective stiffness under the same conditions.

    Basically, if you prefer a little more roll stability (a common preference on lifted trucks), and don't mind a modest decrease in suspension flex, you can leave the end links the way they are.

    Seems like you know what your talking about. How would you measure to see how much you would need to extend the end links? I heard you measure from the bottom of the frame, down to the top of the axle.

    Without being able to eyeball it directly, I would bolt the end links back in, then "imagine" how much longer the links would need to be to put the sway bar arms parallel to the earth.

    Sitting in a hotel at 3AM trying (and failing) to trudge up long-forgotten math, AND estimating the sway bar's and end link's dimensions, I calculate something like a 40% increase in stiffness with a 4" lift. Take that number with a huge grain of salt (I genuinely cannot remember exactly which formulae would apply, and different variations get me anywhere from 30% to 66%, lol). But, just understand that it is not insignificant. Of course, this probably comes out to a 10 or 20% overall increase resistance to rolling motion in the rear suspension (total guestimation), so it's not like you suddenly are riding on bricks. And, fortunately, the closer you get back to parallel the less accurate you have to be. I'd say if you can get within 5-7 degrees of parallel (something like +/- 1" of end-link length), you won't notice the difference.

    Anyways, looking at this crude photo, the solid black line would be the current sway bar position, and the solid blue bar is the current end link position. The dashed black line is where you want the sway bar, so you can essentially eyeball where it would need to be (the orange blob), and extend the link by that amount.
    _181127_023456_052._1.jpg

    Of course, this all assumes you want to actually go back to stock SB stiffness. You genuinely may like how it rides as-is.

    Well said, here’s a question. I recently swapped a 2 inch block and replaced it with icon’s rxt leaf pack. Also have CB +2 shackles Added to that. Which gave me 3-4 inches of lift. They had to remove my trd sway bar.

    They said I need to extend my end links about 8 inches. The truck rides smoother now body roll isn’t really bad. The question is would the ride get stiffer if I reinstall the trd sway bar with the extended end links. Will my leaf springs still work as intended. I don’t want to sacrifice the smoothness for less body roll?

    You will lose some articulation but it should be the same smoothness. And I think they are full of shit if lifting your truck 3 to 4 inches means you need to extend your sway bar end links 8 inches. Some people rotate the mounts on the rear end for the sway bar to mount on the backside of the rear end instead of the bottom. This will gain you a few inches, and many people still use the stock links it just makes for a little less articulation. I would think extending them 2 inches and rotating the sway bar would be perfect.

    Thanks for your input. And that’s what I said. 8 inches!? Doesn’t really make any sense.

    The sway bar will technically make the rig a little stiffer in circumstances where the back axle is not evenly bumped. So, going over a stdaight speed bump, you wont know the difference. But, as one wheel is required to articulate, more of that road force will be transfered to the chassis.

    I really did notice a pretty significant difference taking my front sway bar off on my 4Runner.

    I can see that. I was also thinking of that scenario. I might leave it off. I don’t feel any extra body roll with it off. It’s kinda weird cause when I first installed the rear sway I noticed less body roll.

    But after removing a 2 inch block and replacing it with the icon rxt leaf pack. It still feels like I have a sway bar back there. I don’t know if it’s because these leafs are a lot smoother. I might just leave it off and sell it.

    I dont know the specs of the TRD bar compared to the leafs, but on my 4runner, the rear bar only accounts for a small fraction (1/5 to 1/4) of the combined anti-sway effects of the bars. So, if the new leafs are even moderately stiffer (say, 10-15%), it probably comes out to be a wash.

    IME, removing the front bar is really where you start having to consider various safety aspects and significant changes in driving dynamics. But, most Tundras dont even have a RSB, so Id say it probably isnt a huge deal unless you prefer the flatter rear end when taking smooth corners.

    The have 15% reduced spring weight on stage 1. There 3 stages swapping out different leafs. 2-3 increasing the spring weight

    Interesting! Then, what is more likely is that during normal driving, the rear bar didnt make enough difference for you to know when it was gone.

    I'm working on it
    I have the icon RXT leaf pack with added leaf 4" and CB +3 shackles1.75"

    My truck sits 8"above stock (so essentially 8" lift)

    And need to extend my rear Sway bar end links approx 4" with the spring pack the end link bolts hit the spring during travel

    However I can not find any to purchase
    I spoke with Dave at CB. And he mentioned working on an adjustable set but they are available


    Does anyone know of a set to purchase

    Without spending 300$ to have a set custom made

    Any chance you can confirm that the end links on the helwig are the same as the TRD

    Sleeve length and I.D. they look like I could swamp them out for the TRD end links and be in business

    Take them to a shop, should cost like $50 and a half hour to get them sleeved and extended.

    Unfortunately no I can not. Never seen the helwig swaybar before.
