Progressive STR46 2.0" Smooth Body Shocks (REAR)
2007–2018 Jeep Wrangler JK 3.5-5" Lift
Part #: 46-2003
Overview
The Progressive STR46 2.0" Smooth Body Shocks are engineered specifically for the rear suspension of Jeep Wrangler JK models from 2007 to 2018 equipped with a 3.5 to 5-inch lift. 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, these shocks improve ride quality, handling, and overall vehicle stability without requiring complex manual adjustments.
Designed to complement lifted Jeep Wranglers, the STR46 shocks help maintain proper suspension geometry and enhance the vehicle’s capability both on and off the road. Whether navigating rocky trails or cruising highways, these shocks deliver consistent performance and comfort.
Key Features
The Progressive STR46 shocks feature advanced technology and thoughtful engineering to optimize suspension performance. Key features include:
- Patented FST Technology: Automatically adjusts damping curves in real time for a smooth, controlled ride.
- Optimized for Lifted JK Wranglers: Specifically tuned for 3.5 to 5-inch rear lifts to maintain suspension geometry and ride quality.
- Durable 2.0" Smooth Body Design: Provides robust construction and improved heat dissipation for consistent performance.
- Improved Ride Comfort: Reduces harshness and vibration over rough terrain without sacrificing control.
- Easy Installation: Direct bolt-on fitment with no modifications required for compatible lifted JK models.
- Enhanced Handling: Improves vehicle stability during cornering, braking, and acceleration.
- Corrosion-Resistant Finish: Built to withstand harsh environments and off-road conditions.
Construction & Design
The STR46 shocks feature a smooth 2.0-inch diameter body constructed from high-quality materials designed for durability and longevity. The smooth body design not only enhances the shock’s aesthetic but also improves heat dissipation, reducing fade during extended off-road use. Internally, the patented Frequency Sensitive Technology (FST) uses a unique valving system that responds instantly to changes in terrain and driving dynamics, adjusting damping forces without the need for manual tuning.
Each shock is engineered to withstand the rigors of lifted Jeep Wrangler JK applications, ensuring consistent performance even under demanding conditions. The corrosion-resistant finish protects the shocks from rust and environmental damage, extending their service life.
Installation & Fitment
Installation of the Progressive STR46 shocks is straightforward for Jeep Wrangler JK owners with a 3.5 to 5-inch rear lift. These shocks are designed as direct replacements for the factory rear shocks and require no special tools or modifications. Standard suspension mounting points are used, allowing for a hassle-free upgrade that restores and enhances rear suspension performance.
It is recommended to have the installation performed by a qualified technician or experienced enthusiast to ensure proper torque specifications and alignment. After installation, the shocks immediately improve ride quality and handling characteristics.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
