What is the preload adjustment on these shocks?

These shocks have a five-position cam-style preload adjuster. This lets you easily change the spring tension to match your weight and riding conditions for a more comfortable and controlled ride.

What makes the damping 'velocity sensitive'?

Velocity sensitive valving means the shocks adjust their damping force based on how quickly the suspension is moving. This helps provide a smoother ride over bumps and better control during faster maneuvers.

Do these shocks come with springs?

Yes, these shocks come equipped with progressive rate springs. You can choose between black or chrome springs, and they are available in Standard or Heavy-Duty options for select applications.
