Reducing Body roll?

[alwaysme]

I do alot of highway driving and the body roll is just getting annoying. My truck has a minor lift and i have been looking into strut and body bracing.

Does anyone have any experience with body bracing with land cruisers let alone SUV's? do they help? are they dangerous for our trucks?

Talking about those

am i looking at the correct solution?

Is that device seeking to lock the frame and the body together? Traditionally people use anti-sway bars. And tweaks to suspension pieces. All of which have tradeoffs to consider depending on usage. All lifts tend to exacerbate roll to a small degree. Which truck do you have?

Looks like such bracing would defeat the purpose of the KDSS

 

[RTaylor]

What suspension do you have? And tires?

my tires are 35x12

Care to elaborate ?

I do not think that the sway that you feel is due to lack of stiffness in the body and frame, which is what that brace fixes. I do not think it is a problem on the 200.

What you need to reduce your body roll are tweaks to the suspension and/or anti-roll bars. With KDSS, adjusting the anti roll bars becomes difficult. I do not know of any aftermarket options for stiffer anti roll bars.

The problem is, offroad you want the suspension to flex as freely as possibly. This is why off road buggies dont have anti roll bars.

However, for handling and stability you want little to no roll. KDSS tries its best to be the best of both worlds, but other than disconnecting sway bars like on a Dodge Power Wagon, there is no great answer.

What tire pressures are you running. Try airing up to the max and try it. Any difference to the roll characteristics?

Can pressures in KDSS be boosted? I doubt it. Could KDSS have popped a cork and not be working?

Did this roll issue just begin? What changed?

Do you have a KDSS truck? If not the options change dramatically.

The bracing approach feels wrong, very wrong to me. But I have owned Elsie3 only a week and I flunked Hill Start 101.

Lol, I have sketches of similar braces that I did for the Tundra.... The chassis is nearly identical to the LC from the center crossmember forward. There are handling benefits to these braces, and yes the 200 chassis is a little soft IMO... but you won't feel much, if any reduction in body roll, by installing these.

Those are tall for the 200. Your COG is a good bit higher so this may be your culprit. Try increasing your tire pressure.

Brian knows his stuff.....I would listen to him....

thanks for everyone's input but they all seem very negative towards this mod. I remember I had this upgrade done to a VW and it made a huge difference in bodyroll/handling, I know I'm way off with this comparison but I was really psyched when I was informed that they are now available for the LC200.

Bjowett, if there's barely any noticeable difference then why did you waste your time making/fabricating this mod for the tundra? Maybe the materials were not of high quality?

I am at 34 PSI, 1 PSI over the recommendation so i doubt its the tire pressure. I do have KDSS as well and nothing changed recently except for more highway driving due to my work commute.

Will this mod do more harm than good? should i go for it and be the forums experiment

 

[bjowett]

The braces work, and work well... they improve handling by eliminating chassis twist and keeping the suspension pick-up points in their proper locations. I suppose it could stiffen the structure enough that some reduction in body roll could be felt, but it wouldn't be much. Sway bars along with proper shocks and springs will give one better results... along with the braces.

There is also another big issue with the front suspension, but I'm not letting that cat out of the bag, yet....

Dude they are not negative in nature...they are honest. If that honesty doesn't end up being what you want...don't listen.

You asked...we answered. I have had my LC since NOV 2007 and have noticed some body roll...mainly because it's a ummmm a truck. If you are trying to do 70 mph hair pin turns...then yes body roll is a huge issue. I have most heavy crap on my baby then
any 10 people here and I have never complained about body roll.

We have a few engineering geniuses here.....I would listen to them...or not.....and do what you want.


Oh and that comparison between the VW and the LC....well....that made me laugh...

Sorry but im that kinda guy that thinks installing spacers will improve the handling..

and no kidding I just received some and have yet to install, I'm hoping a combination of spacers, tower brace and an under-body brace will improve the handling/bodyroll. Im only 165 lbs so i slide around in my seat when taking turns, i have to hold on to the arm rest at times. Kinda sucks that's why I find this an issue.

Bjowett,give us a quick brief what is the issue with the fronts?

Ok I am not going to say more then this.

If you are installing spacers for the benefit of body roll.... I don't know what else to say.

Did your VW have a body lift and tires that are 3.5" larger in diameter than stock?

Please believe me, if body roll is the major performance criterion for you, then take out your lift and install stock tires. That will do much more to reduce the body roll you are currently experiencing than any frame bracing could possibly do.

I reduced my body roll by putting in stiffer shocks (OME sport) I think there are others that are even stiffer, best would be to get adjustable ones so you can set it up how you like

 

[xkennx]

To cut down the body roll on my armored TLC's I installed a 38mm front and 33mm rear sway bar. Along with that HUGE rubber spring next to the rear coil spring (bumpstop) that rest about 1/2inch above the rear axle.

But these are all extreme measures that really effect the comfort levels of the TLC.

I prevent body roll by putting a couple of big pillows beside my wife so she doesnt roll over in the night and pinch the blankets!

Hmmmm. Maybe I could strap her to that Toms frame? Who knows, things could get interesting?
