The Progressive Suspension 412 Series Shock for Harley-Davidson models offers a reliable upgrade to improve your motorcycle's suspension performance. Designed specifically for Harley models, this 12-inch shock features a simple yet durable construction that provides an economical solution for enhancing ride quality and handling. The shock's adjustable five-position cam-style spring preload allows riders to easily fine-tune suspension firmness, ensuring optimal comfort and stability across various riding conditions. Made in the USA, the 412 Series shock combines quality craftsmanship with performance, making it a popular choice among Harley enthusiasts seeking an effective suspension upgrade.
Installation may require modifications, such as adjusting or spacing the chain or belt guard on '86-'15 XL models to ensure proper clearance. It’s important to verify that wheel travel can be adjusted without causing contact issues with the swingarm, exhaust, or tires before installing shocks of a different length from OEM. Slight variations in shock length can influence steering characteristics; a longer shock may slightly quicken steering, while a shorter one could slow it down. Heavy-duty applications are recommended for bikes frequently operated near maximum load capacities, ensuring durability and safety under demanding conditions.
This shock is available in multiple aesthetic options, including full show-chrome or black covers, as well as chrome or black springs and end caps. Many styles are approved for road use, but users should consult the latest certification to confirm compliance. All shocks are measured center-of-eyelet to center-of-eyelet, providing consistent sizing for installation. Whether you're looking to improve ride comfort, handling, or load capacity, the Progressive Suspension 412 Series shock is a versatile, cost-effective upgrade crafted to meet the needs of Harley-Davidson riders seeking performance and reliability.
