NEW Dual Rate springs: We've made four new dual rate springs for the SuperShocks. Dual rate springs are soft for their initial half the travel then stiffen up for the second half providing the best of both worlds. These are available in 4 different spring rates. We've powder coated them in 4 different colors for easy identification.

From what we've seen so far running them on our racetrucks the blue one works best in the rear and the red in the front. On our 8 shock heavyweight Brushless E-Maxx we use 4 white in the front and 4 reds in the rear. Heavier (than our racetrucks) 4 shock trucks will find that the blacks in the rear and blues up front will work well. Your use may vary, though these 4 different spring rates should cover all your needs.
