Wilbers 644 WESA Rear Shock K1600GTL

The Wilbers ESA conversion consists of installing your ESA electronics from your original shocks onto new Wilbers shocks which are built to your weight and riding style, and designed to work with your original electronics. All original ESA functions work as designed, but your shock performance is upgraded significantly. Wilbers shocks are fully rebuildable and have a five year warranty.

Our goal is to calibrate your lightest routine load with the zero preload setting on the new shock, and cover your maximum loads within the range of the preload adjuster. To do this, we will be relying on accurate information from you so that the correct spring can be selected and installed with the correct amount of "installed" preload. If possible, please don't guess about the answers to the following questions, use your bathroom scale to confirm. Provide your answers in the comments section on the checkout page. You can copy and paste these questions into the comments area along with your answers. Please contact us if you have any questions.
