Progressive Suspension 412 Series Shock - 11.5 inch Heavy Duty Chrome for Harley-Davidson - Part 412-4066C

The Progressive Suspension 412 Series Shock, model 412-4066C, is designed specifically for Harley-Davidson motorcycles to enhance ride quality and handling. Crafted with a durable chrome finish, this shock absorber offers a cost-effective upgrade to your motorcycle's suspension system, providing improved comfort and stability during rides. Its simple yet robust design ensures long-lasting performance, making it an ideal choice for riders seeking reliable suspension components.
Features include a five-position cam-style spring preload adjuster that allows riders to easily fine-tune their ride stiffness for different loads and riding conditions. This adjustability ensures optimal comfort whether you're cruising on highways or navigating rougher terrain. The shocks are manufactured in the USA and are measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment for compatible Harley models. Some shocks may be approved for road use, but it is recommended to verify current certifications before installation.
When installing these shocks on Harley models from 1986 to 2015, modifications such as spacing the chain or belt guard might be necessary to ensure proper clearance. Slight variations in shock length can influence steering response; a longer shock may provide quicker steering, while a shorter one could result in slower handling. Heavy-duty applications are recommended for bikes frequently operated near maximum load ratings, especially over 50% of the time. Before installation, confirm that your wheel travel and clearance are sufficient to prevent contact with exhaust, chain or belt guards, or tires. This ensures safe, reliable performance tailored to your riding needs.
