DOOLY 8" CARBIDE RUNNER

Each of these dual carbide runners have two single runners mounted to a steel plate, producing a total of four contact lines on the terrain. These four blades with 60° carbide drastically reduce darting as they carve through existing grooves from single runners. This design spreads the PSI across two points, which extends the life of the runner and eases steering. When turning, only one blade per dual runner will contact the terrain, acting like a pair of single runners.
