Rear (anti) sway bar-but not your normal Helwig/TRD options

Howdy Tundra folks,

First off, my truck is a 2017 crew max, with a topo topper, and other weight adding goodies, it's right around 7200lbs. I run ADS triple bypass rear shocks, and deaver 748's, King 3.0's up front along with 37 inch BFG Ko2s. The truck sees it all; moderate speed things in Baja, Moab trails, camping, local trails, crawling (as much as you can with a truck of this size) and just about everything in between. My "favorite" is probably the moderate speed stuff like you find in Baja, or the deserts of CA/NV/OR.

So with that being said, I'm still dialing weight and a few other things before I have the coilovers and shocks valved/tuned by someone smarter than me, beyond turning tubes on the rear, and the knob on the front. In this thought process, I've been investigating a torsion style rear sway bar, on custom mounts, likely through the frame. The spare tire isn't there any more, so I have room. I am thinking that a currie anti rock, or similar rear sway bar that isn't too stiff, would allow the suspension to flex a bit, but also might help my rather portly truck handle some of the go fast stuff better. I've seen them work well as a sort of middle ground on solid axles between no sway bar, and factory stiff sway bar.

From playing with sway bars on other coil, and leaf sprung rigs, I've seen where a rear sway bar can be pretty helpful, and actually force the front suspension to work better, or at least differently. Though I've not yet run a rear bar on a coil front/leaf rear vehicle.

Has anyone done this before, or seen this done? Looking for some input on sway bar thickness and possible end link length (though packaging may dictate the arm length)

 

Sorry to be resurrecting this thing, but this is extremely relevant to my interests. I'm not quite as well equipped as you (Toytec coils/shocks with plans to upgrade soon, u748s in the rear, usually weighing somewhere between 6600-7000 depending on whether the family is with me) and have been considering removing the front sway bar and adding a rear sway bar. I actually watched this video a while ago which gave me the itch to try out a rear sway bar/no front sway bar set-up.

I'm not sure it would work quite as well with our trucks as opposed to the FJ they were experimenting on, considering the difference in weight distribution and coils vs leaf springs. However, he basic concept does seem sound to me; balanced articulation front and rear results in a better general driving experience, to include offroad, than just running no sway bars at all. Moving to a more dedicated "offroad" style sway bar like the Currie Anti-rock may even net a better experience or give you more options

 

This is exactly my line of thinking, however the staggered shock arrangement is making packaging difficult.

If I convert the shock mounts to the forward style, then I would have more room for a sway bar, probably a torsion (anti rock) style bar.

I’ve been busy using the truck, so this project hasn’t moved forward.
