Progressive Suspension 412 Series Shock - 13 Inch Heavy Duty Chrome for Harley-Davidson - Part Number 412-4061C

412 Series Shock - 13" - Heavy Duty - Chrome

The Progressive Suspension 412 Series Shock is specifically engineered for Harley-Davidson models, offering a straightforward and durable upgrade to your motorcycle's suspension system. Designed with a five-position cam-style spring preload adjuster, this shock allows riders to easily fine-tune their ride comfort and handling to match their riding preferences and load conditions. Its robust construction and versatile styling options, including full chrome or black covers with matching springs and end caps, make it a popular choice for riders seeking both performance and aesthetic appeal. Made in the USA, these shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with a wide range of Harley models. Some shocks listed are approved for on-road use; however, riders should refer to the latest certification for current listings. When installing on models from 1986 to 2015 XL, modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance. The adjustable length feature can subtly influence steering characteristics: a slightly longer shock can provide quicker steering, while a shorter one may slow the steering response, offering customization to personal riding style. Heavy-duty applications are recommended for bikes operating near or at maximum load ratings most of the time, ensuring durability and performance under demanding conditions. Before installing shocks that differ from stock length, it is important to verify that wheel travel can be adjusted without causing contact issues with the swingarm, axle, exhaust, chain or belt guard, or tires. Overall, the Progressive Suspension 412 Series Shock enhances your Harley's ride quality, handling, and style, making it an excellent upgrade for serious riders seeking reliability and customization.
