The Progressive Suspension 412 Series Shock (Part Number: 412-4079B) is engineered specifically for Harley-Davidson FLH/T models, offering an effective upgrade to your motorcycle's suspension system. Featuring a simple yet durable design, these shocks are an affordable way to enhance ride comfort and handling. The 12-inch length provides a balanced stance, improving overall stability and ride quality. Constructed with high-quality materials, the shocks are made in the USA, ensuring reliability and long-lasting performance.
The 412 Series shocks include a five-position cam-style spring preload adjuster, allowing riders to fine-tune their ride to match personal preferences or load conditions with ease. The black finish adds a sleek look to your motorcycle, complementing various styling themes. These shocks are suitable for a range of applications, with some options approved for road use, making them versatile for different riding environments.
When installing on '86-'15 XL models, minor modifications such as adjusting or spacing the chain or belt guard may be necessary to ensure proper clearance. Slight variations in shock length can influence steering characteristics; a longer shock might offer quicker steering, while a shorter one can provide a more relaxed feel. Heavy-duty applications are recommended for bikes frequently operated at or near maximum load ratings. Always verify wheel travel compatibility to prevent clearance issues like contact between the swingarm, axle, exhaust, or tires.
Choose from multiple style options, including full show-chrome or black covers, with either chrome or black springs and end caps, to customize your bike’s appearance. The shocks are measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment. Overall, the Progressive Suspension 412 Series Shock is an excellent upgrade for Harley riders seeking improved suspension performance, durability, and a tailored ride experience.
