Sierra constructs this belt with high strength synthetic cords that resist shockload failure and hold low stretch properties, so the belt keeps uniform tension and performance over its service life. The compression section uses a special rubber compound engineered to transfer load forces smoothly and evenly from the pulley to the cords, reducing wear at the drive points.\u003c\/p\u003e\u003cp\u003eThe cogged profile is molded to precise engineering tolerances, which improves the belt's flexibility around smaller pulleys while still maintaining full cord support. The cog geometry also opens up a larger surface area for air circulation, which helps keep the belt cool and prevents damaging heat build-up in the cushion section during continuous operation. Rubber edges along the belt maintain positive, no-slip contact with the pulley grooves for reliable, consistent energy transfer to the crank and power steering pump.\u003c\/p\u003e\u003cp\u003eThis belt is a direct replacement for OEM part number YSC-10260-10-0C on the specified crank\/power steering application.
