Progressive STR47 Remote Reservoir Shocks

2007–2018 Jeep Wrangler JK 1.5-3" Lift

Part #: 47-2001

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 with 1.5 to 3-inch lifts. These shocks incorporate Progressive Suspension’s patented FST (Frequency Sensitive Technology), which dynamically adjusts damping in real time to deliver a smoother, more controlled ride across varying terrains and driving conditions. Designed for off-road enthusiasts and daily drivers alike, the STR47 shocks improve vehicle stability, handling, and comfort without the need for manual adjustments.

Whether tackling rugged trails or cruising on pavement, these shocks provide consistent performance by adapting instantly to changes in road surface and driving style. The remote reservoir design increases fluid capacity and cooling efficiency, reducing fade and maintaining optimal damping during extended use.

Key Features

The STR47 shocks combine advanced technology with durable construction to enhance your Jeep Wrangler JK’s suspension system. Key features include:

• Patented FST Technology: Automatically adjusts damping curves in real time for superior ride quality.
• Remote Reservoir Design: Increases fluid volume and improves heat dissipation for consistent performance.
• 2.0" Shock Body Diameter: Provides enhanced strength and durability for lifted applications.
• Optimized for 1.5-3" Lifts: Perfectly matched to Jeep Wrangler JK models with moderate suspension lifts.
• Improved Ride Comfort: Smooths out bumps and rough terrain without sacrificing control.
• Enhanced Off-Road Capability: Maintains traction and stability in challenging conditions.
• Corrosion-Resistant Finish: Built to withstand harsh environments and extend service life.
• Direct Fitment: Designed for easy installation with no major modifications required.

Construction & Design

The STR47 shocks feature a robust 2.0-inch diameter shock body constructed from high-quality materials to endure the demands of off-road driving and lifted suspension setups. The remote reservoir is connected via a durable hose, allowing for increased fluid capacity and better heat management, which prevents shock fade during prolonged use. Precision engineering ensures consistent damping performance, while corrosion-resistant coatings protect against rust and environmental damage. The internal valving is calibrated to work seamlessly with the FST system, delivering adaptive damping that responds instantly to terrain changes.

Installation & Fitment

These shocks are designed as a direct replacement for the rear shocks on 2007–2018 Jeep Wrangler JK models equipped with 1.5 to 3-inch suspension lifts. Installation is straightforward and typically requires standard hand tools. No major modifications or special tools are necessary, making it accessible for experienced DIYers and professional installers alike. The remote reservoir setup requires proper mounting, which is facilitated by included hardware and mounting brackets designed to fit the JK chassis.
