2022 Toyota Tundra Suspensions Explained: All 6 (!) of Them

Now entering its third generation, the 2022 Toyota Tundra joins the Ram 1500 and the new Ford F-150 Raptor in ditching its rear leaf springs and suspending its live rear axle with links and coil or air springs. The new truck’s three-wheelbase, ladder-frame chassis (one more length than in 2021 to support a choice of bed lengths with each cab design) will now support six distinctly different suspension systems, including three developed by Toyota Racing Development (TRD). Here’s the rundown on these six suspension systems.

All 2022 Toyota Tundra models get a fully boxed frame that’s 10 percent lighter but 20 percent more rigid, thanks to the use of “Dejima” laser-welded tailored blanks that make the frame rails thicker in the places where strength is needed and thinner in the places where it’s not. All Tundras get steel front coil springs, and they all share an identical solid rear anti-roll bar. Base models use single-rate front and rear coil springs and Tokico-brand twin-tube shock absorbers. The spring and damping rates are tailored to suit the equipment level and mass of the given truck. Brakes don’t vary at all between suspension setups, and depending on model and options, all Tundras get 8.0-inch-wide wheels measuring 18 or 20 inches in diameter.

The base suspension can be upgraded with Toyota’s “Load-leveling Rear Height Control Air Suspension” package on the SR5 and Limited models. In addition to load leveling, the Aisin system offers the option of manually lowering the rear of the truck by 1.2 inches to ease loading or while attaching a trailer. It can also be raised by 1.6 inches to improve the departure angle or clear an obstacle. Why not offer air springs all around as Ram does? Toyota determined that the primary benefit of four-wheel air suspension was the ability to lower the truck at highway speeds for improved aerodynamics and fuel economy. But there are only so many development dollars to go around, and because hybrids are a core Toyota brand attribute, the expense was invested in the i-Force Max hybrid powertrain instead.
