We spied the 2021 F-150 Raptor testing and immediately noticed the coil-spring rear suspension—the two previous-generation Raptors had leaf-spring setups in the rear. However, the standard 2021 F-150 still has the leaf-spring setup. Coil-springs open the door to progressive spring rates, and the four trailing link with a panhard rod setup is ideal for high-speed off-roading—they also benefit from greater articulation and wheel travel. Ram has used this configuration since 2009, which will inevitably find it's way under the yet to be released 700-plus horsepower Ram TRX. We also spotted Fox shocks with orange components on them, meaning the version of adaptive live wire dampers from the second generation truck will live on.We spied the 2021 F-150 Raptor testing and immediately noticed the coil-spring rear suspension—the two previous-generation Raptors had leaf-spring setups in the rear.
