Nowaskey Dual Adjustable Shocks are a premium rear suspension upgrade designed for Harley-Davidson Dyna models. Built for riders looking to improve handling, comfort, control, and rear suspension performance, these shocks provide a major upgrade over the factory rear shock setup. Nowaskey Dual Adjustable Shocks allow riders to fine-tune suspension feel based on riding style, road conditions, rider weight, passenger weight, and gear load. With dual adjustable tuning, hand-adjustable preload, high-quality internal components, and rebuildable construction, these shocks deliver the control and confidence needed to push your Dyna harder. Note: Please refer to the Spring Rate Guide below to see which rear shock spring rate corresponds with each rider weight range. These recommendations may vary depending on your exact setup, riding style, passenger weight, gear load, and personal preference.
