Energy Suspension Hyper-Flex bushing kit replaces rubber suspension bushings with Hyper-Flex polyurethane for 2004–2006 Ford F-150 2WD pickup applications. Made in the USA, Hyper-Flex resists oils, coolants and UV exposure and is claimed to outlast rubber up to five times. The kit includes front control arm, sway bar and rear leaf spring bushings to help maintain caster and camber alignment and reduce wheel hop under acceleration.
