Progressive Suspension 412 Series Shock for Harley-Davidson - 13.5 Inch - Black - Part No. 412-4003B
Regular price $379.95 USD
Category:
The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson models, offers a reliable and cost-effective upgrade to enhance your motorcycle's suspension performance. Featuring a durable construction and a simple design, these shocks are built to withstand the demands of daily riding while providing a smoother ride. The five-position cam-style spring preload adjuster allows riders to easily fine-tune their suspension settings for optimal comfort and handling. This adjuster makes it straightforward to customize your ride to match your riding style and load requirements.
Manufactured in the USA, these shocks are available in multiple style options, including full show-chrome or black covers, along with chrome or black springs and end caps. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with a variety of Harley models. When installing shocks on '86-'15 XL models, it's important to verify clearance, as modifications to the chain or belt guard may be necessary to accommodate the new suspension components. A slightly longer shock than stock can alter the head angle, resulting in quicker steering, while a shorter shock may slow steering response slightly.
Heavy-duty applications are recommended for bikes operated near or at the maximum load rating over 50% of the time, ensuring durability under demanding conditions. Before purchasing, confirm that your wheel travel and clearance are sufficient to prevent contact issues with the swingarm, axle, exhaust, chain or belt guard, or tires. Proper installation and adjustment will result in improved ride quality, handling, and overall motorcycle performance, making the Progressive Suspension 412 Series Shock a smart choice for Harley riders seeking a durable and customizable suspension upgrade.
