The Progressive Suspension 444 Series delivers a fully integrated coil‑over monotube design with an internal reservoir, providing consistent damping performance for rear‑mounted street applications. Engineered with an automatic adjustment style, the shock absorber operates in both standard and heavy‑duty duty cycles, allowing riders to maintain optimal control without manual tuning. Each unit is finished in a durable black coating and supplied as a matched pair, ensuring symmetrical handling and a clean, low‑profile appearance.
Featuring a single progressive‑rate spring, the 444 Series offers a spring‑rate range of 90 lb/in to 130 lb/in, delivering a smooth transition from comfort to firm support as the suspension compresses. The extended length of 12.5 in positions the shock for maximum leverage in rear‑mount configurations, while the progressive spring profile accommodates a wide variety of street riding styles. Multiple length and finish options are also available within the series, allowing precise fit‑ment for differing chassis requirements.
