ICON Vehicle Dynamics 138508 Rear Lift Leaf Spring Pack for Ford Super Duty - 5-Inch

The ICON Vehicle Dynamics 138508 rear leaf spring pack delivers 5 inches of lift over stock height when used with OE rear blocks, specifically engineered for 1999-2007 Ford F-250 and F-350 Super Duty trucks. This progressive-rate spring system is designed to enhance both ride quality and suspension performance for your heavy-duty pickup.

Key Features:

• Progressive multi-leaf construction provides smooth ride quality with reduced spring fatigue under load
• Lower spring rate improves overall ride comfort and suspension dynamics
• Bottom 3 leaves feature flat design for secondary overload rate, preventing harsh bottom-outs
• Overload transition point moved further away for superior small bump compliance
• Military wrap front eyelet design ensures maximum durability
• Replaceable bonded rubber bushings provide noise-free operation and effective vibration isolation

The multi-leaf construction minimizes spring sagging under load while maintaining a smooth ride through the full suspension travel. ICON recommends pairing these leaf springs with ICON 2.0 or 2.5 Aluminum Series vehicle-specific tuned shocks for optimal ride quality and performance in both on-road and off-road conditions.
