Upgrade your 2017–2020 Ford F-150 Raptor’s rear suspension with this multi-rate leaf pack with add-in leaf designed for enhanced ride quality, load-handling, and off-road performance. This leaf spring kit replaces the stock rear springs with a user-adjustable pack that lets you tune spring rate and rear lift based on weight, gear or ride preference. With multiple installation configurations and a supplemental leaf included, you get a more controlled ride over rough terrain while managing heavier loads, making it a strong choice for overland builds, towing setups, or lifted suspension systems.
