Progressive Suspension 412 Series Shock - 11.5 Inch Heavy Duty Black 412-4011B for Harley Models
Regular price $379.95 USD
Category:
The Progressive Suspension 412 Series Shock, part number 412-4011B, is engineered specifically for Harley motorcycle models, providing a reliable and cost-effective upgrade to your suspension system. Designed with simplicity and durability in mind, these shocks enhance ride comfort and handling, making them an excellent choice for riders seeking improved performance. The 412 series features a five-position cam-style spring preload adjuster, allowing you to easily customize the ride height and firmness to suit your riding style and load conditions. This adjustability ensures a tailored riding experience, whether you're carrying extra gear or seeking a sportier feel.
Constructed in the USA, these shocks are available in various styles, including full show-chrome or black covers, with options for chrome or black springs and end caps, enabling you to match your bike's aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with your Harley model. When installing on 1986-2015 XL models, modifications to the chain or belt guard may be necessary to provide proper clearance and prevent interference.
Choosing a slightly longer shock can result in a slight alteration of the head angle, offering quicker steering response, while a shorter shock may slow steering for a more relaxed ride. Heavy-duty applications are recommended for bikes that frequently operate near or at the maximum load capacity, ensuring durability under demanding conditions. Before selecting shocks that differ from OEM length, verify that your wheel travel can accommodate the change without causing issues such as clearance conflicts with the swingarm, axle, exhaust, or tires. This careful consideration helps maintain optimal handling and safety during riding.
Overall, the Progressive Suspension 412 Series Shock combines quality, adjustability, and style, making it a practical upgrade for Harley riders seeking enhanced suspension performance and a personalized ride experience.
