T28: 121" x 15" x 1.1" with a 2.52" pitch makes a great handling groomed trail track. The soft rubber compound gives excellent traction, braking, and stability on hard pack surfaces. 2 ply polyester cords, fully clipped, and an efficient lug design make this a great replacement on older sleds that can't handle too deep a lug. The T28 is a great track for high speed lake running, drag racing, or radar runs with a 3 year limited warranty against manufacturer defects.
