Gate G-Force Redline: Designed for the most demanding, turbo-charged off-road CVT applications. With Gates proprietary materials and design, G-Force RedLine CVT belts handle extreme temperatures with excellent heat recovery, while maximizing load and torque capacity, making it one of the most efficient CVT belts currently on the market. First on the market to utilize Ethylene Elastomer compound to address the needs of larger SxS and high-horsepower ORVs in tough riding conditions. Next-generation EE compound offers maximum transverse stiffness and heat resistance, resulting in higher load capacity, higher peak torque capacity, less "heat fade" and less speed loss. Delivers 75% greater dynamic axial stiffness on average, up to 50% lower speed losses and better recovery from temperatures up to +170°C (+338°F) without power loss. Unmatched Temperature Capability - Runs cooler, resists glazing for better recovery and reduced cracking/chunking out after running at temps exceeding +149°C (+300°F). Extended Belt Life - Belt life increased 100-300% versus aftermarket competitive belts in severe duty lab test conditions and in field testing. Higher Power Capacity - Reduced speed (rpm) loss by 50% under high loads and increased load capacity by >10% compared to other aftermarket belt. This G-Series Redline belt is a perfect replacement and /or performance belt for your machine. The top cogs offer better cooling and the aramid cords make it extremely strong.
