The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson models, offering a reliable upgrade to your motorcycle's suspension system. Designed with simplicity and durability in mind, these shocks provide an economical solution to enhance ride comfort and handling. The 11-inch shock features a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune the suspension to match riding conditions and personal preferences. Crafted in the USA, these shocks are built to meet high standards of quality and performance, ensuring long-lasting durability on the road.
The 412 Series Shock is available in various styles, including full show-chrome or black covers, and chrome or black springs and end caps, allowing customization to match your bike’s aesthetic. All shocks are measured from center-to-center of the eyelets, ensuring proper fitment across compatible Harley models. When installing on '86-'15 XL models, modification or spacing of the chain or belt guard may be required for adequate clearance. Slight adjustments to the shock length can influence steering response; a longer shock may lead to quicker steering, whereas a shorter shock can result in slower handling. Heavy-duty applications are recommended for bikes frequently operated near maximum load, ensuring optimal performance under demanding conditions.
Before installing shocks that differ from OEM length, verify wheel travel capacity to prevent clearance issues such as contact with the swingarm, exhaust, or tires. Proper selection and installation of shocks are crucial for maintaining safety and handling performance. Whether you seek improved ride comfort, better load management, or a personalized look, the Progressive Suspension 412 Series Shock provides a versatile and dependable upgrade for your Harley-Davidson motorcycle.
