Progressive Suspension 412 Series Shock - 11.5 Inches Heavy Duty Black for Harley Models

412 Series Shock - 11.5" - Heavy Duty - Black

Upgrade your Harley-Davidson with the Progressive Suspension 412 Series Shock, designed specifically for Harley models to enhance ride quality and handling. With a durable and simple design, these shocks offer an affordable way to improve your motorcycle's suspension performance. The 412 series features a five-position cam style spring preload adjuster, allowing you to easily customize your ride for comfort or performance. Whether cruising or riding aggressively, this adjuster helps you dial in the perfect suspension setup for your riding style. Manufactured in the USA, these shocks are built with quality materials and attention to detail, ensuring reliability and longevity on the road. All shocks are measured from center-of-eyelet to center-of-eyelet, providing precise fitment for compatible Harley models. Some shocks listed are approved for road use; please refer to the latest certification for current compliance. Designed to accommodate various styling preferences, options include full show-chrome or black covers, as well as chrome or black springs and end caps, allowing you to match your bike’s aesthetic. When installing on '86-'15 XL models, modifications or spacers may be necessary for the chain or belt guard to ensure proper clearance. Slightly longer shocks than stock can subtly alter the head angle, resulting in quicker steering, while shorter shocks may slow steering response. For bikes operated near maximum load capacity over 50%, Heavy Duty applications are recommended to handle the additional stress. Before purchasing shocks that differ in length from OEM specifications, verify that wheel travel can be adjusted without causing clearance issues such as swingarm or axle contact with exhaust components, chain or belt guards, or tires. These shocks provide a cost-effective upgrade that improves ride quality, handling, and style while maintaining durability for demanding riding conditions.
