Overview
Introducing the Harpoon, Pro-Line’s latest and greatest solution for high-grip 1/10 Carpet Buggy Racing. The Harpoon features a unique, modern pin design with a round base for more support and longer wear. The directional pin layout gives the racer options to tune forward and site bite characteristics depending on track conditions. A narrow, lower profile carcass improves agility and reduces sidewall fold-over. The outside harpoon-shaped lugs increase high-speed cornering stability in high grip conditions, reducing the need for sidewall CA gluing.
The Harpoon is available in our latest generation CR Compounds, specifically engineered to suit today’s high-grip carpet tracks. Tested by Pro-Line’s factory team of drivers, CR3 (Medium) and CR4 (Soft) compounds provide improved grip and consistency across many different styles of carpet. Included with the Harpoon Rear & 4WD fronts is an updated version of our open cell foam that is denser with a higher rebound and better profile retention than previous foams.
