Carli six-leaf progressive Add-A-Pack rear springs for 2005–2007 Ford F-250 and F-350 4x4 models. These replace the factory lower overload leaf with six thinner leaves to maintain factory load capacity while improving ride quality and reducing harsh rebound from medium to large bumps. Kits include U-bolts and hardware and provide approximately 2.0 inches of lift for compatible rear suspensions.
