Eibach PRO-TRUCK reservoir rear shock for 2015–2022 GM Colorado and Canyon (excluding ZR2/AT4) applications uses a remote reservoir to increase fluid capacity, improving heat dissipation and reducing shock fade. Separating fluid from the nitrogen charge reduces aeration for more responsive damping off-road, helping maintain consistent performance during extended heavy use. The design is intended to enhance off-road duty cycles compared with conventional single-body shocks.
