PROGRESSIVE SUSPENSION 412 Series Shock - 13.5" - Heavy Duty 412-4266B

If you're running your cruiser or touring bike at or near maximum load capacity regularly, OEM shocks simply won't cut it. The Progressive 412 Series Heavy Duty Shock is engineered to handle sustained high-load applications without compromising ride quality or longevity. With nitrogen-charged, velocity-sensitive valving that automatically adapts to changing road conditions, you get predictable handling and comfort whether you're fully loaded or solo.

The five-position preload adjuster lets you dial in the perfect suspension geometry for your specific weight and riding style, while the progressively wound spring provides consistent support throughout its travel. Built in the U.S.A. with quality materials, this is a shock designed for riders who demand reliability over the long haul.
