Progressive Suspension 412 Series Shock - 12.5 inches - Heavy Duty Black for Harley-Davidson 412-4007B

The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson models, offers a simple yet durable upgrade to enhance your motorcycle's suspension performance. With a focus on affordability and reliability, this shock absorber features a five-position cam-style spring preload adjuster that allows riders to easily fine-tune their ride for optimal comfort and handling. Whether you're riding on the street or tackling more demanding conditions, the 412 Series provides versatile performance suited for a variety of riding styles. Made in the USA, these shocks are engineered to fit Harley models with a center-to-center eyelet measurement, ensuring precise installation and effective performance. Some models are approved for road use, but always consult the most recent certification to verify compliance. The shocks are available in multiple style options, including full show-chrome or black covers, and either chrome or black springs and end caps, allowing you to customize your motorcycle's appearance to match your preferences. When installing these shocks on Harley models from 1986 to 2015 XL, modifications to the chain or belt guard may be necessary to ensure proper clearance, especially if the shocks differ slightly from stock length. A longer shock can slightly alter the head angle, resulting in quicker steering, while a shorter shock may produce a slightly slower steering response. Heavy-duty applications are recommended for bikes that frequently operate at or near their maximum load capacity, providing increased durability and support. Before selecting shocks that differ from the OEM length, confirm that your wheel travel can be adjusted without causing clearance issues such as contact with the exhaust, swingarm, or chain/belt guard. The Progressive Suspension 412 Series Shock is an excellent upgrade for Harley riders seeking improved handling, customizable ride height, and enhanced durability.
