ICON 2008+ Ford F250/F350 Super Duty 2in Rear Leaf Spring Expansion Pack

168507 Overview
ICON's 2" Rear Leaf Expansion Pack provides increased suspension lift and better ride quality for lifted 2008-2024 F-250/F-350 Super Duty pickup trucks. The Expansion Pack is designed to replace and improve the center leaves of the stock leaf spring pack while retaining the factory main leaf. This makes the Expansion Pack both cost-effective and an easier installation as it doesn't require complete removal of the leaf spring main leaf from the spring hanger and shackle. The additional leaves included in the pack are designed to optimize ride quality and reduce axle wrap compared to lift blocks. The design also shifts the overload transition point to improve small bump compliance.
The 4-link brackets, upper links, and lower links are sold separately, allowing the 4-link system to be customized for your specific Ford Super Duty year range.
