Dual Rate Spring Assortment, for Traxxas X-MAXX
This spring assortment pack includes one pair each of soft (green), medium (yellow),and firm (red) springs. 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!
The spring separator is custom machined from black delrin for smooth sliding action over the shock body, and the shoulder is offset so the 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.
Upper Spring Rates: Soft (Green) = 1.0 kg/cm, Medium (Yellow) = 1.2 kg/cm, Firm (Red) = 1.4 kg/cm
Lower Spring Rates: Soft (Green) = 1.4 kg/cm, Medium (Yellow) = 1.7 kg/cm, Firm (Red) = 2.0 kg/cm
