Continental has introduced the new Extreme Duty Poly-V belt for the North American heavy-duty aftermarket.

“This belt will be offered in 90 new parts numbers designed for the class 6-8 heavy-duty trucks in the aftermarket,” said Tom Lee, Continental’s marketing manager for North American aftermarket products. “Currently we are offering the belts in eight, 10 and 12-ribbed profiles, packaged in a new sleeve design.”

The Extreme Duty Poly-V straight-ribbed belt performs better under higher underhood temperatures, thereby resulting in lower emission standards, the company said. It comes with a 100,000-mile guarantee.

“This belt has four times the flex life of previous belts. We wanted to see how it would perform with heat that was 20% higher than what is mandated by the SAE standards,” said Lee. “The test was conducted in an extreme heat environment to simulate an engine with a number of accessories and low air circulation. With advanced EPDM polymers, the Extreme Poly-V belt meets higher performance standards.”
