DESCRIPTION 5-Layer Construction: Engineered with a robust 5-layer structure, this CVT belt integrates dual nylon tooth coatings, a reinforced double-thick neoprene rubber layer, and woven aramid fibers. This design delivers optimal resistance to demanding off-road conditions, significantly enhancing durability. Enhanced Heat Dissipation: Withstanding temperatures from -40°C up to 140°C, this snowmobile drive belt minimizes overheating-related and cold failures. Its heat-resistant properties extend operational life, allowing more trail time and less maintenance. Precision Tooth Profile: The clutch belt features an elastomer-impregnated nylon fabric on its precisely engineered tooth surface. This ensures even force distribution, maintains optimal performance, reduces speed fluctuations, and prolongs the drive belt’s service life. 45,000N Tensile Strength: Built to endure forces up to 45,000 Newtons, the belt demonstrates exceptional resistance to stretching and breaking, ensuring consistent and reliable performance during speed variations.
