Progressive Suspension 412 Series Shock - 13.5 inch - Chrome - FLH 412-4073C

The Progressive Suspension 412 Series Shock is specifically designed for Harley-Davidson models, providing an affordable and reliable upgrade to your motorcycle's suspension system. With a simple yet durable construction, these shocks enhance ride comfort and handling while maintaining a sleek appearance. The 412 series features a five-position cam-style spring preload adjuster, allowing riders to fine-tune their suspension setup easily for different riding conditions and loads.
Constructed in the USA, these shocks are available with various style options, including full show-chrome or black covers, and either chrome or black springs and end caps. All shocks are measured from center of eyelet to center of eyelet, ensuring compatibility. When installing on '86-'15 XL models, modifications or spacers may be necessary for proper clearance around the chain or belt guard. It's recommended to verify that wheel travel can accommodate shocks of different lengths without causing contact issues with the swingarm, exhaust, or tires.
Adjusting the length slightly longer than stock can result in a minor change to the head angle, offering quicker steering response, while a slightly shorter shock may produce slower steering characteristics. Heavy-duty applications are suitable for bikes operated near maximum load ratings over 50% of the time, providing increased durability under demanding conditions. Proper installation and compatibility checks ensure optimal performance and safety, making the Progressive 412 Series shocks a versatile choice for Harley-Davidson enthusiasts seeking improved ride quality and handling.
