This is the Pro-Line front rear Impulse 1.9 black plastic bead-loc wheel. These Impulse wheels are designed to not only look scale but to be super easy to use since they only require 6 screws per wheel for mounting tires. The unique 3-piece plastic wheel design bolts together in the back and locks on to Pro-Line's incredible list of 1.9" crawling tires. The back of this 12mm hex wheel also accepts Pro-Line's Brass Brake Rotor Weights (sold separately) for additional looks and performance.
Fits: Front or Rear of Rock Crawlers
