Progressive Suspension 422 Series Adjustable Shocks - Chrome - Heavy-Duty 422-4001C

422 Series Adjustable Shocks - 1,117 lb/in - Chrome - Heavy-Duty

The Progressive Suspension 422 Series Adjustable Shocks are designed to deliver superior ride quality and durability for heavy-duty motorcycle applications. These shocks feature a show chrome cover that provides corrosion resistance and an attractive finish. With fully adjustable ride height and spring preload, you can fine-tune the suspension to match your riding style and load requirements, ensuring optimal handling and comfort on the road. The pair includes progressive-rate coil springs and purpose-built monotube dampers, which work together to provide a smooth, controlled ride even over rough terrain. The dampers are nitrogen-charged, eliminating internal oil cavitation and helping to maintain consistent damping performance while resisting heat-induced fade during extended riding sessions. These shocks can be adjusted up to 2 inches lower than stock, offering versatility for custom setups or specific riding conditions. They are recommended for heavy-duty applications where the motorcycle operates at or near the manufacturer's maximum load capacity over 50% of the time. Before installing shocks that differ from OEM length, it is essential to verify that your wheel travel can accommodate the change without causing clearance issues, such as contact between the swingarm or axle and exhaust, chain or belt guard, or tires. Proper fitment ensures safety and optimal suspension performance for your motorcycle.
