    I have a 2019 double cab with 3” Toytec Boss coil overs on the front, CB + 2 Shackles and Toytec Aluma 2.0 shocks on the rear. Truck drive pretty smooth on asphalt highway but on certain stretches of concrete highway the truck bounce is really bad. Tried putting 180 lbs of sand bags in the back which didn’t do much but I helped a friend move some fairly heavy outdoor furniture and on the same stretch of road truck was super smooth. Obviously I don’t want drive around with a ton of weight all the time so any advice on how to address this would be great! Thanks in advance

    I think you can try the TRD rear sway bar. Could help.

    You may have to switch lanes to find a more smooth one and cruise at about 72 mph.. you should be good more or less to go...

    Yeah, I second this. While I’m not advising you to drive at an illegal speed ;), I’ve been experiencing bed bounce in my 2017 and altering speed improves it.

    Back when I had a bed rack, I had no bed bounce.

    Been considering getting one but just didn’t want to harshen the ride....I know they improve body roll but also limit suspension travel a bit.

    yeah when I had it loaded down with that furniture (if I had to guess 350 lbs or so) no bounce at all. I went over the same stretch of road a couple days ago unloaded it it felt like the rear end was bouncing off the road. Just don’t want to drive around loaded all the time.

    I think the bed rack acted kind like a bed stiffener, as well as adding a bit of weight... only ~75 pounds though.

    I don't think the sway bar harshen the ride. It will limit body roll and if you go off-roading will limit suspension travel. however on normal roads will not harshen your ride quality. my 2 cents.

    As far as I know this problem doesn't exist on every newer Tundra, just some, which is why this is still a mystery. My Sport, and lots of other Sport owners here have claimed they don't have this problem. The only thing our trucks have that some others don't are the rear sway bars and differently tuned shocks. It might be worth the money to try a rear bar, if it doesn't solve the main problem, its still a huge handling upgrade. Good luck.

    I have a 2002 and driving down I 70 there is a certain spot or seperation in the highway that makes the arse end of the truck that seems to bounce a couple inches to the left. Pucker up mode doing 65 mph lol. Now I try to avoid it but would be nice not to have to.

    Yeah didn’t really think I would have to avoid certain stretches of road in a brand new truck when I bought it lol....I increased my air pressure the other day and seems to help a bit but now it’s been cold AF the last week so not sure if that is having an impact but it’s annoying.

    Can’t get bed bounce if your wheels never touch the ground.

    The sway bar won't harshen the ride at all, and the limited travel is only really relevant if you're rock-crawling or on some very uneven trails. For the street its a great upgrade.

    I wonder if there is a connection between DC vs Crewmax and the bed bounce. I've heard some folks complain about it, but I've ridden in probably 5 different Tundras, including my own, in the last year and never experienced it, but all were Crewmax.
    Maybe the difference in weight distribution between the two models is the difference, as I assume the DC has less weight over the rear axle (I'm only assuming it does, but it makes sense that it would). The Crewmax seems like its more even front to rear, while the DC has more weight forward, since the cab is further away from the rear axle. Maybe someone could start a poll and see who has the bed bounce and who doesn't and whether they drive a DC or CM. Or it could be just crappy roads vs. less crappy roads.

    My 07 has brutal bed bounce on concrete highways. I'm hoping new springs and shocks and a sway bar will fix it. My best trick so far is to take the long way around.

    The fact that your's is a DC AND a long bed and you have brutal bed bounce supports my theory of the DC vs CM.
    The weight distribution front to rear probably makes the weight over your rear axle way less than a CM.
    Do you know anyone with a crewmax? Maybe you could hitch a ride with them over the same stretch of road... I'd be interested if it does the same thing. Although there are lots of variables like suspension and tires, if it does it in the CM too then at least you'd know its the road and not the truck.

    No, I think I'm the only Toyota owner I know. All my truck friends drive Dodges. Maybe I'll test drive a crew max over that stretch of highway, if I can find one.

    I have the same issue in my 17' DC . usually on i80 concrete sections by the salt lake or on ut201 . In a few weeks I'll have my leer 100xr. I'll let you know if that solves it.

    I would bet that has a lot to do with just ho much of the frame is c-channel. Remember , the frame is Boxed under the engine, then A modified C with the ends of the c folded over under most of the cab, and finally open C-channel under the length of the bed. More open C-Channel would Lead to more wet noodle frame wiggle. Shorter beds would have less open C and more semiclosed C and therefore would reasonably be expected to twerk a bit less.

    I'm sure that's the case. I've owned 4 trucks - one quadcab (or CrewMax), one single cab, and two SuperCab (F150 and F250).

    The single cab truck never had much bed bounce; nor does my CrewMax. (I mean, yeah, if I go over some SERIOUSLY ridiculous gravel roads, sure.) But no matter WHAT I did, the F150/F250 SuperCabs had a ton of bed bounce. I replaced shocks, rear sway bar, etc. and it 'helped' but not much.

    Other forums are full of people complaining of the same thing with their trucks; and the consensus there is the same - it's extended cab/SuperCab.

    I would double check the torque on your shackles. After putting on deaver springs, I torqued to factory specs and still bouncy. They recommended going to 90 ft/lbs with red loctite. Much smoother now.

    The only potential downside to the sway bar is reduced articulation so it's only a problem if you rock crawl.

    This exact thing has been happening to me. Double cab, BDS 7" lift + stock leafs + BDS shackles. When hauling a bunch of hunting gear/camping gear last fall, going over highway overpass expansion joints made the rear bounce inches in either direction. Yes, agree on the pucker factor. Eyes bugged out, too, & death grip on steering wheel.
    Happened again a couple months ago when hauling furniture to my daughter's first apartment. Highway speeds going over those expansion joints made the rear bounce all over. It happens without hauling a load, but it's much more pronounced, in my experience, with a heavy load. Yes, I know the 7" lift w/ big fart-knocking 37" tires will exacerbate this.
    That was it for me. I've since installed CB shackles and OME springs. Without a load, I still notice it on highway when going over bumps, joints, but doesn't seem to be as pronounced yet. With a load...TBD.

    Edit: I'm glad I found this thread. This has been bothering me for a little while now.
