The Progressive Suspension 412 Series Shock is designed specifically for Harley Dyna models, offering a reliable and cost-effective upgrade to your motorcycle's suspension system. Made in the USA, this shock provides enhanced durability with a simple yet robust design, ideal for riders seeking improved ride quality and handling. Its 12-inch length, measured from center-of-eyelet to center-of-eyelet, ensures compatibility with a variety of Harley Dyna models, and the heavy-duty construction makes it suitable for bikes operated at or near maximum load ratings frequently.
Featuring a five-position cam-style spring load preload adjuster, this shock allows riders to easily customize their ride stiffness to suit their preferences and riding conditions. This adjustability ensures optimal comfort and control, whether you're tackling rough roads or enjoying smooth highway cruising. The shock's black finish offers a sleek, aggressive look that complements the motorcycle's aesthetic.
Some or all shocks listed are approved for road use; however, it is important to verify current compliance certificates. When installing this shock on '86-'15 XL models, modifications to the chain or belt guard may be necessary for proper clearance. Additionally, selecting a shock that is slightly longer or shorter than stock can subtly alter the head angle, resulting in quicker or slower steering responses, respectively. Riders considering different lengths should confirm wheel travel and clearance to avoid contact issues with the exhaust, swingarm, axle, or tires. This shock is a versatile upgrade that balances performance, durability, and style, making it an excellent choice for Harley Dyna owners seeking to improve their motorcycle's ride quality.
