What is the main benefit of the 5-position preload adjuster?

The 5-position cam-style preload adjuster allows you to easily change the stiffness of the suspension. You can dial it in to better suit your weight, whether you're riding solo or with a passenger and luggage.

What makes the damping performance consistent?

These shocks use nitrogen-charged, multi-stage velocity-sensitive valving. This advanced internal design helps maintain consistent damping control across a range of speeds and road conditions.

Are these shocks suitable for heavy loads?

Yes, the 412 Series offers Standard or Heavy-Duty spring options for select applications, and the 5-position preload adjuster allows you to compensate for heavier loads, providing a more controlled ride.

They're designed to provide consistent damping and allow you to adjust the ride to your liking, whether you're carrying extra weight or just prefer a firmer feel.

The five-position cam-style preload adjuster is a practical touch, letting you easily fine-tune the suspension's stiffness to match your riding style and load. This adjustability is key to getting the most out of your bike, whether you're a solo rider or carrying a passenger and gear.

This particular set comes in a 13-inch length with a black finish and black springs, fitting a wide range of Harley-Davidson touring models like the Road King, Electra Glide, and Road Glide. They offer a noticeable improvement in how your bike handles, making longer rides more comfortable and spirited riding more controlled.
