Progressive Suspension 412 Series Shock - 12 Inch - Black for Harley-Davidson - Model 412-4051B

Upgrade your Harley-Davidson with the Progressive Suspension 412 Series Shock, designed specifically for optimal performance on Harley models. This 12-inch shock features a simple yet durable construction that offers an affordable enhancement to your motorcycle's suspension system. The shock's robust design aims to improve ride comfort and handling, making it suitable for a variety of riding conditions. Its black finish provides a sleek appearance, complementing your bike’s aesthetic while offering resistance to corrosion and wear. Made in the USA, this shock ensures quality and reliability, giving you confidence during every ride. Its center-to-center measurement guarantees proper fitment, and the adjustable five-position cam-style spring preload allows you to easily dial in the ride quality according to your preferences. Whether you're tackling daily commuting or long-distance touring, this shock provides improved stability and responsiveness. When installing on '86-'15 XL models, some modifications such as chain or belt guard adjustments may be necessary to ensure proper clearance. Slight variations in length compared to stock shocks can subtly influence the motorcycle's head angle, resulting in either quicker or slower steering responses. Heavy-duty applications are recommended if your bike frequently carries maximum load or is used near its load capacity. Before choosing shocks different from OEM length, verify that your wheel travel can accommodate the change without interfering with components like the swingarm, exhaust, or tires. Compatibility with road use is confirmed for most models, with certification details available for reference. Overall, the Progressive Suspension 412 Series Shock offers a reliable, customizable upgrade for Harley-Davidson enthusiasts seeking enhanced ride quality and style.
