Pro-Line X-Maxx dual rate spring assortment
Pro-Line have introduced a dual rate spring assortment for the Traxxas X-Maxx truck. Specifically developed for Traxxas’ popular truck, the spring assortment pack includes a pair each of soft, medium and firm upper and lower springs that can be mixed and matched to give tons of tuning options. The main benefit of using dual rate springs is to 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. The included 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.
