Eibach PRO-TRUCK reservoir rear shock for 2007–2015 Toyota Tundra 4WD is tailored for 0–1.5" rear lift applications and uses a remote reservoir to improve heat dissipation and reduce shock fade. The reservoir design separates fluid from nitrogen charge to limit aeration, delivering more consistent damping for off-road driving where heat and repeated cycles can degrade traditional shock performance.
