These shocks deliver superior ride quality and handling performance. Featuring advanced Frequency Sensing Technology (FST) and deflective disc valving, the 444 Series automatically adjusts damping to provide a smooth and controlled ride, no matter the road conditions.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Progressive Suspension 444 Series shocks utilize Frequency Sensing Technology (FST) to dynamically adjust damping based on bump frequency, ensuring optimal comfort and control. The deflective disc valving further enhances the shock's ability to react to changing road conditions. Pre-load is easily adjustable by hand, eliminating the need for special tools. These shocks feature a progressive-rate spring and high-pressure gas charge for consistent performance. Built with quality materials and made in the USA, the 444 Series shocks are designed for durability and long-lasting performance. The coilover monotube design ensures efficient heat dissipation and consistent damping, even under demanding conditions. Heavy-duty applications are recommended for bikes operating near their maximum load rating over 50% of the time.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eExperience superior ride quality with Frequency Sensing Technology (FST) that automatically adjusts damping.\u003c\/li\u003e\n \u003cli\u003eEnjoy easy pre-load adjustments by hand, no special tools required.\u003c\/li\u003e\n \u003cli\u003eBenefit from consistent performance thanks to the progressive-rate spring and high-pressure gas charge.\u003c\/li\u003e\n \u003cli\u003eImprove handling and control with deflective disc valving.\u003c\/li\u003e\n \u003cli\u003eDurable construction and made in the USA for long-lasting performance.\u003c\/li\u003e\n \u003cli\u003eOptimized for heavy-duty applications and demanding riding conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eBrand: Progressive Suspension\u003c\/li\u003e\n \u003cli\u003eProduct Name: Shock Absorber\u003c\/li\u003e\n \u003cli\u003eVendor Part Number: 444-4021B\u003c\/li\u003e\n \u003cli\u003eType: Coilover Monotube\u003c\/li\u003e\n \u003cli\u003eMounting Position: Rear\u003c\/li\u003e\n \u003cli\u003eAdjustment Style: Automatic\u003c\/li\u003e\n \u003cli\u003eColor\/Finish: Black\u003c\/li\u003e\n \u003cli\u003eDuty: Heavy Duty\u003c\/li\u003e\n \u003cli\u003eExtended Length: 13.50\" (343.00 mm)\u003c\/li\u003e\n \u003cli\u003eSpring Type: Single Progressive Rate\u003c\/li\u003e\n \u003cli\u003eProgressive Spring Rate: 105 lb\/in - 150 lb\/in (1.88 kg\/mm - 2.68 kg\/mm)\u003c\/li\u003e\n \u003cli\u003eUnits: Pair\u003c\/li\u003e\n \u003cli\u003eReservoir Location: Internal\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eShocks slightly longer than stock may alter head angle slightly and provide quicker steering.
