Overview

The Progressive STR47 2.0" Remote Reservoir Shocks are engineered specifically for the rear suspension of Jeep Wrangler JK models from 2007 to 2018 equipped with 3.5 to 5-inch lifts. These shocks incorporate Progressive Suspension’s patented FST (Frequency Sensitive Technology) design, which dynamically adjusts damping curves in real time to deliver a smoother, more controlled ride across diverse terrains and driving conditions. Ideal for off-road enthusiasts and daily drivers alike, the STR47 shocks improve handling, reduce harshness, and enhance overall vehicle stability.

Designed to replace factory rear shocks, the STR47 series provides superior performance for lifted Jeep Wranglers, accommodating increased suspension travel and load demands while maintaining comfort and control. Whether tackling rugged trails or cruising on pavement, these shocks adapt instantly to changing road surfaces, making them a reliable upgrade for Jeep owners seeking enhanced suspension capability.

Construction & Design

The STR47 shocks are built with a rugged 2.0-inch diameter shock body crafted from high-strength materials to withstand the rigors of off-road use. The remote reservoir design increases oil volume and surface area, which helps dissipate heat more effectively, preventing fade during extended or aggressive driving. Precision-engineered internal valving and durable seals ensure consistent damping performance and long service life. The shocks are finished with corrosion-resistant coatings to protect against environmental elements, making them suitable for harsh conditions.

No additional modifications or special tools are typically required, allowing for a hassle-free upgrade. Proper installation ensures optimal shock performance and vehicle handling characteristics. It is recommended to have the shocks installed by a qualified technician or experienced enthusiast familiar with lifted Jeep suspensions.
