The Ford Raptor is an extremely capable truck that has captured the attention of the off-road community over the past few years. Since the Raptor’s release ICON Vehicle Dynamics’ engineers have pushed this vehicle to extremes to develop the most sophisticated suspension components on the market. From the brutal deserts of the Southwest, to the deep snow of Michigan’s U.P., to the wooded trails of the East coast ICON suspension systems have been put to the test and performed flawlessly. Unable to leave “well-enough” alone, ICON is aiming to once again raise the bar in Raptor performance with the release of a multi-rate leaf spring that represents the latest component in the ICON complete suspension system for the Gen 2 Raptor.

To fully take advantage of ICON’s current 2017-2020 F150 Raptor offerings, ICON engineers decided to scrap the OE leaf springs and develop a replacement that addressed a couple issues found in the R&D process. The result is a user-adjustable multi-rate leaf pack that offers a major performance gain for almost every Raptor setup imaginable. To increase the ride quality of the truck and gain additional droop travel, the spring rate was designed to be slightly lighter than factory, which was found to be on the stiff side for smaller, choppier terrain. While most Raptor owners will embrace the improved ride quality this provides, there are those who have outfitted their trucks with a significant amount of weight and require more load carrying capability. Understanding this, ICON engineers designed the leaf pack with an additional leaf (included with kit) that can be exchanged or added to the pack, yielding an additional 20% or 40% spring rate that will work well for heavier vehicles.

Features like tip inserts and leaf separators add to ride comfort, while a triple military wrapped front and rear half wrapped eyelet increases durability and strength of the leaf spring. A rebound leaf was added to reduce the axle wrap of the Raptor, which was another issue that has been found through ICON’s extensive testing. These features all combine for a ride that is night and day smoother on choppy trails, dirt roads, and even in the parking lot. No matter if it’s a spare tire, chase rack, a roof top tent, or more this ICON leaf spring is the perfect option for 2017-2020 Ford F150 Raptors looking to improve the ride quality and performance with a reliable and proven bolt-on solution.

Further expanding the product line up, these multi-rate leaf packs are also approved for fitment on all 2021-2023 Ford F-150 submodels besides Raptor with specific ICON 2.5 Aluminum Series rear shock absorbers, offering improved ride quality, increased rear wheel travel, and reduced axle wrap with the elimination of the factory rear blocks. Their customizable spring rates and lift heights makes for a great option for vehicles with taller lift heights or builds with increased static weight in the rear. Pairing them with the ICON 1” lowering shackles also allows for fine tuning of the truck’s rear ride height and fitment on a wide range of suspension setups.

*Sold individually. You will need to add qty of 2 if you need a full set*
