ICON Triple-Rate Rear Springs, 0.75-1.25-Inch Lift | 2022-2026 Toyota Tundra

These are the higher-riding counterpart to ICON’s 51210 springs. TRD-package Tundras gain about 0.75 inch in the rear; non-TRD trucks gain roughly 1.25 inches. The spring itself uses separate droop, ride and overload rates so the truck can stay compliant around normal ride height and add support as load or compression increases.

A third-gen owner running this spring as part of an ICON setup described the on-road improvement over a spacer lift as night-and-day. That is the right expectation: the point is not just the extra inch, it is replacing a height-only solution with a spring designed around the truck’s movement.

Not compatible with load-leveling rear air suspension; ADAS recalibration is required after install.
