ICON 2in Rear Leaf Spring Expansion Pack for 2008-2025 Ford F-250/F-350 Super Duty (168507)

Fits select 2008-2025 Ford F-250 and F-350 Super Duty 4WD pickup trucks (XL, XLT, Lariat, King Ranch, Platinum, Limited, FX4, and Harley-Davidson Edition).

The ICON Vehicle Dynamics 168507 Rear Leaf Expansion Pack is engineered to provide a 2-inch rear lift while significantly enhancing ride quality. Unlike a full replacement leaf pack, this system is designed to replace the center leaves of your factory spring pack while retaining the OE main leaf. This approach simplifies installation by eliminating the need to remove the leaf spring from the frame hanger and shackle, making it a more efficient and cost-effective upgrade.

Technically tuned for the Ford Super Duty platform, this expansion pack optimizes the spring rate to improve small bump compliance by shifting the overload transition point. It also effectively reduces axle wrap—a common issue with lift blocks—ensuring more stable power delivery to the ground. When installed in conjunction with factory rear blocks, it provides a consistent 2-inch lift height for a leveled or lifted stance.
