Carli six-leaf progressive Add-A-Pack rear springs for 2008–2010 Ford F-250 and F-350 Super Duty applications. The pack replaces the lower overload leaf with multiple thinner leaves to maintain factory load capacity while improving ride comfort and mitigating harsh rebound from medium to large bumps. Includes necessary U-bolts and hardware and yields about 2.0 inches of lift where applied.
