This is a Dual Rate Spring Assortment for X-MAXX®. Do you want to add more performance, style and function to your X-MAXX® shocks? Then Pro-Line has the ultimate Spring solution for you! Pro-Line is proud to introduce fully functional Dual Rate Springs specifically developed for your X-MAXX®. The spring assortment pack includes a pair each of Soft (Green), Medium (Yellow) and Firm (Red) Upper and Lower springs that can be mixed and matched to give you tons of tuning options. The main benefit of using Dual Rate Springs is that you can have a softer initial combined spring rate for gliding over the small choppy bumps, but then transition to a much firmer rate once the Upper Spring is collapsed to absorb the Big Hits! It’s truly the best of both worlds! The spring separator is custom machined from Black Delrin for smooth sliding action over the shock body and the shoulder is offset so upper spring collapses consistently for proper performance. The Upper Springs are Black and the Lower Springs are bright Zinc Coated for a chrome-like finish to set your X-MAXX® apart from the rest. Get your own Pro-Line Dual Rate Spring Assortment today!
