The Traxxas TRX-4 Traxx Deep-Terrain Tread Set is an optional upgrade for the Traxxas TRX-4 Traxx (8880). The Deep-Terrain Treads adapts the terrain dominating power of Traxx-equipped vehicles to extreme surface conditions like deep snow, sand, and mud. The engineered treads dig deep and pack into loose surfaces for maximum bite in even the most challenging conditions. A wide contact surface provides additional flotation to keep your Traxx-equipped model running strong.
