Progressive Suspension 412 Series Shock - 12.5 inch - Standard/Heavy Duty Black 412-4205C The Progressive Suspension 412 Series Shock is specifically designed for Harley-Davidson models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Made in the USA, this shock features a five-position cam-style spring preload adjuster that allows riders to easily fine-tune their ride comfort and handling. Whether you're looking for a standard or heavy-duty application, the 412 Series provides reliable support suited for various riding conditions. The black cover and spring options lend a sleek appearance that complements many Harley models, but other style options like chrome covers and springs are also available to match your aesthetic preferences. Compatibility with Harley models from 1986 through 2015 makes this shock a versatile choice for many riders seeking an affordable suspension upgrade. The center-to-center measurement ensures proper fitment, but riders should verify wheel travel clearance when installing shocks that differ from stock length to prevent contact with components such as the swingarm or exhaust. The adjustable preload feature helps tailor the ride to your load, whether you're carrying extra gear or solo riding. A longer shock may slightly alter the head angle for quicker steering, while a shorter shock can provide a more stable, slower steering response. Heavy-duty applications are recommended for bikes frequently operated near the maximum load rating, ensuring durability under demanding conditions. Please consult the latest certification and ensure proper fitment when selecting shocks for your Harley-Davidson motorcycle.
