Progressive Suspension 412 Series Shock - 12 Inch Standard Black for Harley-Davidson - Part 412-4049B

412 Series Shock - 12" - Standard - Black - H-D

The Progressive Suspension 412 Series Shock, model 412-4049B, is designed specifically to enhance the suspension performance of Harley-Davidson motorcycles. Its simple yet durable construction offers an affordable upgrade option that improves ride quality and handling. The shock features a five-position cam-style spring preload adjuster, allowing riders to easily customize their ride stiffness for optimal comfort and control in various riding conditions. Made in the USA, this shock ensures quality craftsmanship and reliable performance for Harley models from 1986 to 2015, particularly suitable for XL series bikes.

This shock absorber is available in multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, enabling riders to match their bike’s aesthetic preferences. All shocks are measured from center-of-eyelet to center-of-eyelet, providing a consistent fit and straightforward installation. When installing on certain models, such as the '86-'15 XL series, some modification or spacing of the chain or belt guard may be necessary to ensure proper clearance, especially when changing the shock length.

Adjusting the shock length slightly longer than stock can result in a modest change to the head angle, offering slightly quicker steering, whereas shorter shocks may slow steering response. Heavy-duty applications are recommended for bikes frequently operated near the manufacturer’s maximum load capacity, typically over 50%. Before selecting shocks that differ from the OEM length, it’s essential to verify that wheel travel can be adjusted without causing clearance issues with components like the swingarm, axle, exhaust, chain or belt guards, or tires. This ensures a safe and optimized riding experience while maintaining the integrity of your motorcycle's suspension system.
