Gen2 sequoia IRS: anyone tinker with it yet?

[mkmarz]

Any one play with the IRS yet? I’ve got air bags and am considering a spring swap at some point.

The airbags are excellent for towing, but I’m considering a different route for the truck.

define tinker! lots of us have lifts

Sway bar disconnects or other items to get more wheel travel.

A little tinkering Modified 2008 Toyota Sequoia 4x4

Nice rig, looks like he pulled out the sway bar ends. Flex is still a joke, but i supposed that’s to be expected.

In effort to provide some "tech" I nabbed this info. I'm not sure how long stuff stays on BaT

"Black 18″x9″ MK6 wheels wear 35″x12.5″ Falken mud-terrain tires all around, including the rear-mounted spare. Braking is from cross-drilled rotors with ceramic pads. The suspension has been lifted 4″ using steel Dobinsons rear lift coils, custom spacers, and Tundra SPC upper control arms as well as Bilstein 6112 front dampers and custom-mounted Bilstein 5160 rear shocks. "

his rear coils pic concerns me, though he does have a heavy rear bumper, but also with additional spacers... idk

here's mine for comparison:

Thanks for posting JB, can you share more info on your shock set up? What Spring? Do you run a rear sway bar?

i have a more detailed build thread Here on Tundras.com

 

[mkmarz]

The second gen I'm considering building is a factory rear air suspension. I'm considering converting it to coils. From looking at the parts diagrams, the upper mount (attached to frame) has the same part number as coil springs. The lower control arms differ. I may order some rear coils to see if I can get it to work without having to buy new control arms.

Has anyone attempted this?

Really enjoyed reading your build thread.

How is the ride with the Kings and Dobinsons added to the rear?

Thanks

The ride is amazing! i have adjusted the rears several times, and i think i have it dialed in for smooth ride and feeling controlled.

i would highly recommend this combo.

Late to the party but this is a slow sub group - The front end of the TREE feels pretty stiff and responsive.

The ass end definitely is a little squishy. Is there an OE height option to make it a little firmer? is that what you all have done?
