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

412 Series Shock - 12.5" - Heavy Duty - Black - H-D

The Progressive Suspension 412 Series Shock offers a reliable upgrade for Harley-Davidson motorcycles, designed to enhance ride quality and suspension performance. Featuring a simple yet durable design, these shocks are an economical way to improve your motorcycle's handling and comfort. Crafted specifically for Harley models, the 412 series incorporates a five-position cam-style spring preload adjuster, allowing riders to fine-tune their ride with ease for various loads and riding conditions.

Constructed in the USA, these shocks are available in multiple style options, including full show-chrome or black covers, with either chrome or black springs and end caps. They are measured from center-of-eyelet to center-of-eyelet, ensuring a precise fit for compatible Harley models. Some shocks are approved for road use, but it is advisable to check the latest certification to confirm compliance. Proper installation may require modifications, such as adjusting or spacing the chain or belt guard on models from 1986 to 2015 XL, to ensure adequate clearance and prevent contact with exhaust components or tires.

Choosing the correct shock length is essential, as a slightly longer shock than stock can provide quicker steering and a different head angle, while a shorter shock may result in slower steering characteristics. Heavy-duty applications are recommended for bikes often operated near their maximum load capacity, typically over 50% of the time. Before making any modifications or purchasing shocks different from the OEM length, verify that wheel travel can be adjusted without interference from the swingarm, axle, exhaust, or chain/belt guard. These shocks are designed to deliver improved suspension performance, ride comfort, and handling, making them a valuable upgrade for Harley-Davidson enthusiasts seeking durability and customization.
