( Brand: Progressive Suspension ), ( Manufacturer Part Number: 412-4018C ), ( Part Type: Shock )
The 412-4018C 13.5 Harley Shocks Progressive Suspension is a high-performance aftermarket suspension system designed specifically for Harley-Davidson motorcycles. This shock absorber set is a significant upgrade from the original factory-installed shocks, offering improved handling, comfort, and control on the road.
The 412-4018C shocks are progressive, meaning they provide a progressive spring rate. This means the spring rate increases as the suspension compresses, providing better support and control in various riding conditions. The progressive spring rate allows for a more comfortable ride during cruising, while still offering the necessary support and stiffness during hard cornering or acceleration.
The shocks are designed with a 13.5-inch length, which is ideal for Harley-Davidson models with long travel suspension systems. This length provides additional travel and improved suspension performance, allowing the bike to absorb bumps and road imperfections more effectively.
The shocks are also nitrogen-charged, which helps to maintain consistent damping performance over the life of the shock. The nitrogen gas helps to eliminate air pressure fluctuations, ensuring consistent performance in various temperature and elevation conditions.
The 412-4018C shocks are also adjustable, allowing riders to fine-tune the suspension to their preferred riding style. The shocks feature preload adjustability, allowing riders to adjust the amount of force required to compress the spring. They also have rebound adjustability, allowing riders to adjust the rate at which the shock returns to its original position after compression.
The shocks are made of high-quality materials, including chrome-plated bodies and polished springs, which not only provide excellent performance but also add a touch of class to your Harley-Davidson. The shocks are also designed to fit seamlessly with your Harley-Davidson's existing suspension components, making installation easy and straightforward.
In conclusion, the 412-4018C 13.5 Harley Shocks Progressive Suspension is a high-performance aftermarket suspension system that offers improved handling, comfort, and control on your Harley-Davidson. With its progressive spring rate, nitrogen-charged design, and adjustable features, this shock absorber set is a must-have upgrade for any Harley-Davidson enthusiast looking to take their riding experience to the next level.
