Rather than relying on an offset tensioner, this belt's materials and profile allow it to be stretched over pulleys and maintain proper tension during operation. It’s a common replacement for models that originally shipped with a factory stretch-fit belt and is sized and constructed to match OE fitment and performance expectations.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Gates stretch-fit design simplify replacement?\u003c\/h3\u003e\n\u003cp\u003eThe stretch-fit construction removes the need for a movable tensioner during installation, enabling a quicker change with fewer components.
