Progressive Suspension 412 Series Shock - 12 inch Heavy Duty Black for Harley FL Models

412 Series Shock - 12" - Heavy Duty - Black - FL

The Progressive Suspension 412 Series Shock, part number 412-4080B, is engineered specifically for Harley FL models, offering a reliable upgrade to enhance your motorcycle's suspension performance. Designed with simplicity and durability in mind, these shocks provide an economical solution for riders seeking improved ride quality. The black finish adds a sleek, understated look that complements various motorcycle styles. Each shock features a five-position cam-style spring preload adjuster, allowing you to easily dial in your ride for optimal comfort and handling based on load and riding conditions. The shocks are made in the USA, ensuring high manufacturing standards and quality control. They are measured from center-of-eyelet to center-of-eyelet, making installation straightforward for compatible Harley models. When installing on '86-'15 XL models, some modifications or spacers might be necessary to ensure proper clearance with the chain or belt guard. A slightly longer shock can subtly alter the head angle, providing quicker steering response, while a shorter shock may slow steering for a more relaxed ride. These shocks are suitable for heavy-duty applications, especially when operating near the bike's maximum load capacity over half the time. It is important to verify that changing shock lengths will not interfere with clearance issues such as swingarm contact, exhaust, or tire rubbing. Some variants of these shocks are approved for road use, as confirmed by recent certification. The 412 Series offers multiple style options, including full show-chrome or black covers, along with chrome or black springs and end caps, allowing riders to customize their motorcycle's appearance. Overall, the Progressive Suspension 412 Series Shock provides a durable, adjustable, and stylish upgrade for Harley owners seeking to improve ride quality and handling without compromising reliability or style.
