Pro-Line’s new dual stage crawler foams for the SCX24 and other 1/24 vehicles that utilize 1.0 size wheels. Firmer molded inner foams provide better sidewall support while the softer open-cell ring allows the tire to conform to terrain. Each insert is contoured to precisely fit Pro-Line’s existing line of tires for a slip-free fit and a more confident feel on the rocks. Sold in a convenient four pack these inserts are proudly made in the USA.
