Rear Expansion Pack Kit for Toyota Tundra (2007-2021)

Rear Expansion Pack Kit, fitment-checked

An expansion pack adds leaves to what is already on the truck rather than replacing the pack outright, which is the difference between this and a full RXT leaf pack. It covers the 2007-2021 Toyota Tundra with no trim restriction on the record.

Two ways to address a sagging or under-sprung Tundra rear, and this is the additive one: an expansion pack works with the existing leaf pack instead of replacing it. That makes it a different purchase from a complete pack even though both live in the same category and cover the same 2007-2021 Tundra. At 75 lb boxed it is substantial hardware. ICON records a Lifetime warranty and an installation guide is available to download. No trim qualifier appears on the fitment record.
