Get ready for some big-wheeled adventures! Kids will love designing and building impressive monster trucks as they mix and match oversize truck bodies, chassis with massive wheels and stylish accessories—in lots of combinations. Then kids just pull back each finished truck…let it go…and watch it zoom into action! Perfect for kids to race on their own or against friends, the set includes 15 snap-together pieces that are a breeze to connect. Truck bodies measure 5 3/4" in length.
