ICON 2017-2020 Ford Raptor/2021-2023 Ford F-150, Multi Rate Leaf Pack Spring w/Add In Leaf

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.; +2.25" lift height over stock (unloaded); +1.00" lift height over stock w/ 400lb constant load; Option #3; +40% spring rate over option #1; +3.00" lift height over stock (unloaded); +0.50" lift height over stock w/ 850lb constant load; MULTI-RATE INFO 2021-2023 F-150 XL, XLT, Lariat, King Ranch, Platinum, and Limited; Option #1 (as shipped); +2.50" lift height over stock (unloaded); Option #2; 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.; +20% spring rate over Option #1; +3.75" lift height over stock (unloaded); +2.50" lift height over stock w/ 400lb constant load; Option #3; +40% spring rate over option #1; +4.50" lift height over stock (unloaded); +2.00" lift height over stock w/ 850lb constant load; MULTI-RATE INFO 2021-2023 F-150 Tremor; Option #1 (as shipped); +1.50" lift height over stock (u
