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 insalltion 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 maximuze the performance of the Tundra's rear springs, consider the ICON Multi-Rate Leaf Spring, part # 158509.Shipping Notes

Perfect Quality.
Format: Hardcover, Format: Hardcover
Cloth bound cover with printed foil design on the front cover. The lettering color ; as well as the picture illustrations, are entirely printed in blue ink. There is a removable price sticker on the back of the book, which it is hard to remove without it leaving glue residue behind, therefore I myself left it as it was. The sprayed edges are also of blue metallic color. Very nice quality book I recommend buying it. My copy of the book had only a very tiny indentation on the edge of the top front cover but hardly anything to make a fuss about.
