Progressive STR47 Remote Reservoir Shocks

2007–2018 Jeep Wrangler JK 3.5-5" Lift

Part #: 47-2002

Overview

The Progressive STR47 2.0" Remote Reservoir Shocks are engineered specifically for Jeep Wrangler JK models from 2007 to 2018 equipped with 3.5 to 5-inch lifts. These front shocks incorporate Progressive Suspension’s patented FST (Frequency Sensitive Technology) design, which dynamically adjusts damping in real time to deliver a smoother, more controlled ride across varying 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 handle the increased suspension travel and demands of lifted Jeep Wranglers, these shocks provide superior performance whether navigating rocky trails, highway cruising, or rugged backcountry roads. The remote reservoir design improves heat dissipation, reducing shock fade during extended use and maintaining consistent damping performance.

Key Features

The STR47 shocks combine advanced technology with durable construction to offer a reliable upgrade for lifted Jeep Wrangler JKs. Key features include:

• Patented FST Technology: Automatically adjusts damping curves in real time for optimal ride quality.
• Remote Reservoir Design: Increases fluid capacity and improves heat dissipation to prevent fade.
• 2.0" Shock Body Diameter: Provides enhanced strength and durability for off-road use.
• Optimized for 3.5-5" Lift Kits: Ensures proper suspension geometry and travel.
• High-Quality Seals and Components: Designed to withstand harsh environments and extend service life.
• Improved Ride Comfort: Smooths out bumps and rough terrain for better driver and passenger comfort.

Construction & Design

The Progressive STR47 shocks feature a robust 2.0-inch diameter shock body constructed from high-strength materials to endure the rigors of off-road driving. The remote reservoir is connected via a durable hose, allowing for increased fluid volume and better heat management, which is critical during extended or aggressive driving sessions. Precision-engineered internal valving and seals ensure consistent damping performance and long-term reliability. The shock’s design balances stiffness and compliance to maintain traction and comfort across diverse terrain types.

Installation & Fitment

Installation of the Progressive STR47 shocks is straightforward for Jeep Wrangler JK owners with 3.5 to 5-inch lift kits. These shocks are direct replacements for the front suspension components and require no major modifications. Basic hand tools and mechanical knowledge are sufficient for installation, though professional installation is recommended for optimal results. Proper alignment and torque specifications should be followed to ensure safety and performance.
