U-Bolts Required: This kit does not come with U-bolts, and new U-bolts will be required for proper fitment of these leaf springs. ICON's 12" U-Bolts for the 1999 to 2010 Super Dutys and 2011-2016 Super Dutys are perfect if you plan on deleting your rear blocks. If you're going to use rear blocks, call us directly at 623-434-5277 to find the U-bolt kit that fits your truck.
Longer Rear Shocks Required: The Leaf Spring Kit will result in a ride height that's too tall for your stock shocks. We recommend using ICON's 2.0 Aluminum Series Rear Shocks.
