Progressive Suspension 412 Series Shock - 12 Inch Standard Chrome for Harley-Davidson - Part 412-4013C

The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson motorcycles, offering a reliable and cost-effective upgrade to enhance your bike's suspension performance. Crafted with durability in mind, this shock features a simple yet robust design that provides improved ride quality and handling. The 12-inch length provides a balanced stance, promoting better stability and comfort during rides. Its chrome finish adds a sleek, classic look that complements Harley models perfectly. The shock includes a five-position cam-style spring preload adjuster, allowing you to easily fine-tune your ride for various loads and riding conditions, ensuring optimal comfort and control. All shocks in this series are made in the USA, adhering to high manufacturing standards for quality and longevity. These shocks are measured from center-of-eyelet to center-of-eyelet, ensuring accurate fitment and compatibility. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard for proper clearance, especially when using shocks longer or shorter than the stock length. Slight adjustments to the shock length can subtly alter the head angle, influencing steering response—longer shocks tend to quicken steering, while shorter shocks can slow it down. Heavy-duty applications are recommended for bikes operated near maximum load capacity over 50% of the time, providing additional strength and durability under heavy use. Before selecting shocks different from the OEM length, verify that your wheel travel and clearance points, such as swingarm, axle, exhaust, and chain or belt guard, are compatible to prevent contact issues and ensure safe, reliable performance.
