Progressive Suspension 412 Series Shock - 13.5 Inch - Chrome - Model 412-4018C for Harley-Davidson

412 Series Shock - 13.5" - Standard - Chrome

The Progressive Suspension 412 Series Shock (Part Number 412-4018C) is engineered specifically for Harley-Davidson models, offering an affordable yet reliable upgrade to your motorcycle's suspension system. With a durable and straightforward design, these shocks enhance ride comfort and handling, making them an excellent choice for riders seeking increased performance without compromising reliability. The 412 Series features a five-position cam-style spring preload adjuster, allowing you to easily customize the ride height and firmness to match your riding style and load conditions. This adjustability ensures optimal comfort whether you're cruising or tackling uneven terrains, providing a tailored riding experience. Made in the USA, these shocks are available in multiple styles, including full show-chrome or black covers, with either chrome or black springs and end caps, allowing you to match your bike's aesthetic preferences. All shocks are measured center-of-eyelet to center-of-eyelet, ensuring proper fitment for your Harley-Davidson. When installing on 1986-2015 XL models, some modifications such as spacing the chain or belt guard might be necessary to ensure proper clearance. Slightly longer shocks than stock may alter the head angle, resulting in quicker steering, while shorter shocks could produce a slightly slower turn-in. Heavy-duty applications are recommended for bikes frequently operated near maximum load ratings, typically over 50% of the time. Before purchasing shocks that differ from OEM length, verify that your wheel travel can accommodate the change without causing clearance issues, such as contact with the swingarm, exhaust, chain, or tire. Designed for versatility and durability, the Progressive Suspension 412 Series Shock improves your motorcycle's handling, stability, and overall riding experience, whether for daily commuting or long-distance touring.
