Overview

The Progressive STR46 2.0" Smooth Body Front Shocks are engineered specifically for Jeep Wrangler JL models from 2018 through 2026 and Jeep Gladiator JT models from 2020 through 2025 equipped with 2-3" suspension lifts. 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, the STR46 shocks enhance vehicle stability, comfort, and handling without the need for manual adjustments.

Designed to complement lifted Jeep applications, these front shocks improve suspension articulation and reduce harshness, making them a reliable upgrade for those seeking improved ride quality and performance on and off the pavement.

Construction & Design

The Progressive STR46 shocks feature a rugged 2.0" smooth body design crafted from high-quality materials to ensure long-lasting durability and resistance to environmental elements. The smooth body finish helps prevent dirt and debris accumulation, which can affect shock performance over time. Internally, the patented Frequency Sensitive Technology (FST) employs a unique valving system that automatically adapts damping characteristics based on the frequency of suspension movement, delivering a balanced combination of comfort and control.

Precision engineering ensures these shocks maintain consistent performance under demanding off-road conditions while providing a refined ride on paved roads. The robust construction is complemented by corrosion-resistant coatings, making them suitable for all-weather use.

Installation & Fitment
