2018–2026 Jeep Wrangler JL 2-3" Lift

Part #: 47-2006

Overview

The Progressive STR47 2.0" Remote Reservoir Shocks are engineered specifically for the rear suspension of Jeep Wrangler JL models from 2018 through 2026 with 2-3" lift kits. These shocks incorporate Progressive Suspension’s patented FST (Frequency Sensitive Technology) design, which dynamically adjusts damping in real time to provide a smoother, more controlled ride across a variety of terrains and driving conditions. Ideal for off-road enthusiasts and daily drivers alike, the STR47 shocks enhance vehicle stability, comfort, and handling without the need for manual adjustments.

Designed to replace factory rear shocks, the STR47 series offers improved performance for lifted Jeep Wranglers, helping to maintain ride quality and suspension articulation even under demanding off-road use. Their remote reservoir design increases oil capacity and improves heat dissipation, reducing fade during extended or aggressive driving.
