Thunder's proven quick turn geometry remastered from the ground up. Extra room for larger wheels, less wheel bite. Taller 54mm axle height and remastered geometry give T-II's a deeper, more responsive turn while maintaining speed and control. Designed to slide on baseplate instead of wheels. Better lock in for nose, tail and blunt slides. New redesigned baseplate with shifted bolt hole pattern and rounded contours. Reinforced hangers with high-grade aluminium axle enclosures added for extra strength and longer truck life. New 100du tapered clear pivot cups. Newly developed 90du single tapered bottom bushing designed for stability without sacrificing response. 8.75" axle for skateboards 8.62"-8.85".
