Experience superior ride quality and enhanced performance with the Progressive Suspension 412 Series Rear Shocks. Designed specifically for powersports applications, these non-adjustable shocks deliver consistent damping thanks to their durable twin-tube internal construction.
Made from robust steel, the shock bodies are finished in sleek black to resist wear and provide a tough look that complements any motorcycle or powersport vehicle. These shocks are gas charged to reduce fade and maintain smooth control over varying terrain and conditions.
Installation is straightforward with eyelet mounts at both the upper and lower ends, ensuring a secure fit. Polyurethane bushings in black contribute to a quiet ride while providing durability and resilience.
Each shock comes equipped with coilover springs that have an adjustable preload, allowing you to fine-tune the ride firmness for your comfort or performance needs. The springs feature a black finish and a firm spring rate of 270/315 pounds per inch, providing excellent support and handling.
The shocks measure 12.63 inches at extended length and 10.12 inches collapsed, offering the right balance between travel and compact design. Sold as a pair, they are a great upgrade for rear suspension systems seeking reliability and solid performance without complicated adjustments.
