About this product

The 412 Series is engineered for performance and durability, making it an excellent choice for discerning riders.
Description
The Progressive Suspension 412 Series Cruiser Shocks are designed to automatically adjust to varying riding conditions, thanks to their nitrogen-charged design and multi-stage, velocity-sensitive valving. These shocks provide consistent damping and control, enhancing stability and reducing rider fatigue. The progressively wound steel spring delivers superior ride quality and responsive handling, while the five-position cam-style preload adjuster allows you to fine-tune the suspension to your specific needs and load. These complete shock assemblies feature stylish chrome springs and covers, adding a touch of elegance to your motorcycle. Heavy Duty (HD) applications are recommended for bikes consistently operated near their maximum load capacity.
