Eibach PRO-TRUCK rear reservoir shocks for 2015+ Ford F-150 4WD are designed for use with 0–1.5" lift setups and use a remote reservoir to improve fluid cooling and reduce shock fade. By separating fluid from the gas charge, the reservoir configuration helps control aeration and maintains responsiveness under repeated heavy use, offering a tuned shock option for off-road and lifted-truck applications.
