Unlike traditional add-a-leafs that obtain lift height at the cost of stiffening the spring rate and sacrificing ride quality, the 2007-2021 Toyota Tundra Rear Leaf Spring Expansion Pack replaces all the factory secondary leaves while only retaining the factory main and overload springs. This allows us to soften the spring rate to increase ride comfort while also increasing ride height, maintaining load and towing capacities, and increasing wheel travel when paired with ICON shock absorbers. A new U-bolt kit is also included to make the installation a breeze. Features like these make the 2007-2021 Toyota Tundra Rear Leaf Spring Expansion Pack is an excellent option for most users, but for those looking to maximize the performance of the Tundra's rear springs, consider the ICON Multi-Rate Leaf Spring, part # 158509.

Leaf springs are common for cars that have solid axle suspension. Leaf spring kits can be used to lift or lower vehicles, provided you install them with the proper U-bolts and other accessories.
