Progressive Suspension 412 Series Shock - 11 Inch Standard Chrome for Harley FL/FX Models (Part #412-4043C)

412 Series Shock - 11" - Standard - Chrome - FL/FX

Designed specifically for Harley-Davidson models, the Progressive Suspension 412 Series Shock offers a simple yet durable upgrade to enhance your motorcycle's suspension performance. The shock features a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune their ride for optimal comfort and handling. Made in the USA, this shock is constructed with high-quality materials and available with various style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, enabling customization to match your bike’s aesthetic.

Measuring approximately 11 inches from center-of-eyelet to center-of-eyelet, the 412-4043C shock is designed for straightforward installation on Harley models, including '86-'15 XL series. Some modifications may be required when installing on certain models, such as spacing the chain or belt guard for proper clearance. The shock's slightly longer length compared to stock models can provide a quicker steering response by slightly altering the head angle, while a shorter version may result in a more relaxed steering feel.

Heavy-duty applications are recommended for bikes operated near or at the manufacturer's maximum load rating over 50% of the time, ensuring durability and performance under demanding conditions. Before selecting shocks different from the OEM length, verify that your wheel travel can be adjusted without causing clearance issues, such as contact with the exhaust, swingarm, axle, chain or belt guard, or tire. Overall, the Progressive Suspension 412 Series Shock is an excellent choice for riders seeking a cost-effective, reliable upgrade that enhances ride quality and handling on Harley-Davidson FL/FX models.
