Give Your Truck A Smoother Lifted Ride

If you are looking to add lift without sacrificing comfort, the ICON 2" Rear Leaf Spring Expansion Pack is a smart upgrade for your Super Duty. Instead of relying on lift blocks that can cause axle wrap and a harsher ride, this kit adds carefully engineered leaves to the middle of your factory spring pack. The result is a smoother ride with better control, especially when driving over uneven pavement or rough backroads. Because it reuses the factory main leaf, installation is easier and more cost effective than replacing the entire spring pack. This setup also shifts the overload transition point, which helps your truck absorb smaller bumps with less jarring feedback. Whether you use your truck for daily driving, towing, or trail exploring, this pack delivers both lift and comfort in a way that blocks simply can’t. It is a simple change that makes a big difference every time you hit the road.

Engineered For Lift Strength And Ride Quality

The ICON 168507 Rear Leaf Spring Expansion Pack is designed for 2008-2025 Ford F250 and F350 Super Duty 4WD trucks. Providing approximately 2 inches of rear lift when paired with OE blocks, this expansion pack replaces the factory center leaves while retaining the main leaf for strength and proper fitment. The added leaves are shaped to optimize suspension function, reducing axle wrap compared to standard lift blocks and improving overall drivability. Another key benefit is the repositioned overload transition point, which enhances small bump compliance and creates a more refined ride. Installation is simpler than a complete leaf pack replacement, making it both time and cost efficient. Depending on the truck model and rear block setup, new U-bolts may be required for proper installation. Sold individually, two expansion packs are needed per vehicle, and it is not recommended for F350 dual rear wheel applications. Backed by ICON’s Limited Lifetime Warranty, this pack ensures long-term performance and reliability.
