Progressive Suspension 412 Series Shock - 13.5 Inches - Standard Chrome 412-4018C for Harley Models

The Progressive Suspension 412 Series Shock, part number 412-4018C, is specifically engineered for Harley-Davidson motorcycles, offering an effective and affordable upgrade to your bike's suspension. With a length of 13.5 inches, these shocks provide a balance between ride comfort and handling, making them suitable for a variety of riding conditions. Crafted with durability in mind, the 412 Series features a simple yet robust design that enhances your motorcycle's performance without complicating installation or maintenance. The chrome finish adds a sleek aesthetic to your bike, complementing its classic appearance and providing corrosion resistance for long-lasting durability. These shocks incorporate a five-position cam-style spring preload adjuster, allowing you to easily fine-tune your ride according to load and terrain, ensuring optimal comfort and stability every time you hit the road. Some or all shocks listed are approved for road use; however, it’s important to review the latest certification details for compliance. Multiple style options are available, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing you to customize the look to match your bike’s style. Made in the USA, the 412 Series shocks are measured from center-of-eyelet to center-of-eyelet, ensuring accurate fitment. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard for proper clearance. Slight variations in shock length can influence steering dynamics, with longer shocks providing quicker steering and shorter shocks offering slower response. For bikes operated near maximum load capacity over 50% of the time, Heavy Duty applications are recommended. Before installing shocks that differ from OEM length, verify that your wheel travel and clearance are sufficient to prevent contact issues with the swingarm, exhaust, or tires, and to ensure proper function. This versatile suspension upgrade is designed to improve ride quality, handling, and aesthetics, making it a reliable choice for Harley enthusiasts seeking performance enhancements.
