The ICON Vehicle Dynamics Rear Leaf Spring Expansion Pack for the 2007-2021 Toyota Tundra is engineered to increase ride height and performance without sacrificing ride quality. Unlike traditional add-a-leaf kits that stiffen the suspension, this system replaces all factory secondary leaves while retaining the factory main and overload springs. This design allows for a softer spring rate that improves ride comfort while maintaining load capacity, towing capability, and increasing wheel travel when paired with ICON shock absorbers. A complete U-bolt kit is included to ensure a straightforward installation.
