Construction & Design

The STR46 shocks feature a robust 2.0-inch smooth body design crafted from high-quality materials to ensure long-lasting durability and consistent performance. The smooth body reduces internal friction, allowing the shock to respond quickly and smoothly to suspension movements. At the core of the design is Progressive’s patented FST technology, which uses internal valving to continuously adjust damping forces based on the frequency of suspension inputs. This eliminates the need for manual tuning and provides a balanced ride whether you’re cruising on pavement or tackling rugged trails.

These front shocks are engineered for direct fitment on Jeep Wrangler JL (2018–2026) and Gladiator JT (2020–2025) models lifted between 3.5 and 4 inches. Installation is straightforward, requiring no special tools or modifications to your vehicle’s suspension. The STR46 shocks replace factory front shocks and integrate seamlessly with existing suspension components, maintaining proper geometry and ride height. Professional installation is recommended to ensure optimal performance and safety.
