Regular price $379.95 USD
Category:
Upgrade your Harley motorcycle with the Progressive Suspension 412 Series Shock, designed specifically for FLH and T models. This 13-inch shock offers a straightforward, durable solution to enhance your bike's suspension performance. Its simple design ensures reliable operation while providing a cost-effective way to improve ride quality. The shock features a five-position cam-style spring preload adjuster, allowing you to easily dial in your preferred ride height and firmness for optimized handling and comfort. This adjustability makes it suitable for a variety of riding conditions and rider preferences, ensuring a personalized experience.
Constructed in the USA, the Progressive Suspension 412 Series Shock combines quality materials with thoughtful engineering. It is available with different style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing you to match your bike's aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with your specific model. When installing on '86-'15 XL models, some modifications or spacers may be necessary for the chain or belt guard to ensure proper clearance. It’s important to verify wheel travel and clearance before installation, especially if selecting shocks longer or shorter than stock, to prevent contact issues with the swingarm, exhaust, or tires.
Heavy Duty Applications are recommended for bikes operated near or at maximum load capacity over 50% of the time, providing additional durability and performance under demanding conditions. Slight adjustments to the shock length can alter the head angle, resulting in quicker or slower steering response, which can be tailored to your riding style. With the Progressive Suspension 412 Series Shock, you receive a high-quality, American-made component designed to deliver improved handling, comfort, and durability for your Harley motorcycle.
