Progressive Suspension 412 Series Shock - 12 Inch Standard/Heavy Duty for Harley FXD 412-4046B

412 Series Shock - 12" - Standard/Heavy Duty - Black - FXD

The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson FXD models, offers a reliable and cost-effective upgrade to your motorcycle's suspension. Its simple yet durable design enhances ride comfort and handling by improving shock absorption and stability on the road. Made in the USA, this shock features a versatile construction suitable for a range of riding conditions, including heavy-duty applications where maximum load capacity is frequently exceeded.
Equipped with a five-position cam-style spring preload adjuster, riders can easily customize the ride height and firmness to match their preferences or riding terrain. The shocks are available with various styling options such as full show-chrome or black covers, along with chrome or black springs and end caps, allowing for personalized aesthetics that complement your bike's look. Each shock is measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment for Harley FXD models from 1986 to 2015.
Installation considerations include potential modifications for models with chain or belt guards to ensure proper clearance. Slight variations in shock length can influence steering characteristics, with longer shocks providing quicker steering and shorter shocks offering a more relaxed turn. Heavy-duty versions are recommended for riders operating near the maximum load capacity most of the time, ensuring durability and performance under demanding conditions. Before selecting shocks that differ from stock length, verify that wheel travel and clearance are adequate to prevent contact with exhaust, swingarm, axle, or tires, maintaining safe and reliable operation.
