The 412 Series Shock includes a five-position cam-style spring preload adjuster, allowing riders to easily dial in their preferred ride height and stiffness for a customized riding experience. The shock's center-to-center measurement ensures compatibility with Harley Dyna models from 1986 through 2015, but proper installation may require modifications such as adjusting or spacing the chain or belt guard to prevent clearance issues.

The Heavy Duty version is recommended for bikes regularly operating near their maximum load capacity, offering enhanced durability under demanding conditions. Before installation, it is important to verify that wheel travel adjustments do not result in contact with exhaust components, swingarm, axle, or other parts. This shock is designed for both street and highway use, with some models approved for road use; please refer to the latest certification for confirmation.
