Construction & Design

The STR46 shocks feature a robust 2.0-inch smooth body construction crafted from high-strength materials to endure the rigors of off-road use. The smooth body design minimizes the accumulation of dirt and debris, which can impair shock performance and longevity. Internally, the shocks utilize Progressive’s patented FST system, which employs a unique valving mechanism that senses frequency changes and adjusts damping accordingly. This dynamic response ensures optimal shock absorption whether on rough trails or paved roads.

The use of premium seals and components enhances durability and reduces maintenance requirements, making these shocks a reliable upgrade for serious Jeep owners.
