Upgrade your cruiser or touring bike's suspension with the Progressive Suspension 412 Series shocks.

Designed with performance and durability in mind, the 412 Series shocks are an excellent choice for discerning riders.

Description

The Progressive Suspension 412 Series cruiser shocks feature nitrogen-charged dampers and multi-stage, velocity-sensitive valving. This advanced technology automatically adjusts to varying riding conditions, providing consistent performance whether you're cruising down the highway or navigating winding roads. The progressively wound steel spring further enhances ride quality and handling, absorbing bumps and vibrations for a smoother ride. With a five-position cam-style preload adjuster, you can easily fine-tune the suspension to match your riding style and load. These complete shock assemblies come with chrome springs and covers, adding a touch of style to your bike. For bikes frequently operated near their maximum load rating, the Heavy Duty (HD) versions are highly recommended. Each unit measures 13.00" in extended length and uses a coilover monotube design. These shocks provide a progressive spring rate from 90 lb/in - 130 lb/in (1.60 kg/mm - 2.30 kg/mm).

Important to know

Check for potential contact between the swingarm/axle and exhaust, as well as chain/belt guard or tire contact. Always ensure safe and proper installation.
