About this product
Upgrade your Harley-Davidson's suspension with the Progressive Suspension 412 Series Shocks. These shocks offer a blend of classic styling and modern performance, providing a comfortable and controlled ride. With their durable construction and adjustable preload, the 412 Series is a cost-effective way to improve your motorcycle's handling and ride quality.
Description
The Progressive Suspension 412 Series shocks are specifically designed for Harley-Davidson models, offering a significant upgrade over stock suspension. The simple yet robust design ensures long-lasting performance and reliability. Featuring a five-position cam-style spring load preload adjuster, you can easily fine-tune your ride to match your load and riding style. The gas-charged damping method provides consistent performance, absorbing bumps and vibrations for a smoother, more controlled ride. Available in multiple styles, including full show-chrome or black covers, with chrome or black springs and end caps, you can customize the look to match your bike's aesthetic. These shocks are measured center-of-eyelet to center-of-eyelet, ensuring accurate fitment. These heavy-duty shocks are an ideal choice for motorcycles operated at or near the manufacturer's maximum load rating more than 50% of the time.

Important to know
When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard to allow proper clearance. A shock which is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering. A shock which is slightly shorter than stock may alter the head angle slightly and provide somewhat slower steering. Before purchasing or attempting to install shocks that are different than the OEM length, confirm that your wheel travel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact as well as chain/belt guard or tire contact. Please refer to the most recent certificate for current road use approval listings.
