Sometimes you need additional load capacity to help with the heavy hauling you do with your Toyota truck. By adding an add-a-leaf kit to your Toyota Tundra, Tacoma, 4-Runner and Pickup, you will get additional height and weight capacity. The add-a-leaf will insert into your existing Toyota leaf spring, making the spring stronger and creating a safer ride when hauling heavy loads. These kits will give your truck up to 3” of lift and are sold in pairs.
