Eibach PRO-TRUCK Reservoir Rear Shock – 2021–2026 Ford F-150 2WD 2.7L / 3.5L EcoBoost / 5.0L

Upgrade your truck’s suspension performance with the Eibach PRO-TRUCK Reservoir Rear Shock. Designed for 2021–2026 Ford F-150 2WD models, this high-performance monotube shock features an external reservoir that increases oil capacity for improved heat dissipation and consistent damping performance. Eibach’s PRO-TRUCK RESERVOIR shock utilizes a piggy-back reservoir system that provides additional fluid capacity to help reduce shock fade and maintain consistent performance during prolonged off-road use.

The added cooling capacity and increased fluid volume allow the shock to deliver better suspension control, smoother ride quality, and improved stability on rough terrain or under heavy loads. This design also supports mild suspension lifts while helping maintain predictable handling and ride comfort both on and off the pavement.
