Gates K030303SF Stretch Fit Micro-V Serpentine Belt - 3-Rib 30.35 Inch

The Gates K030303SF Stretch Fit Micro-V Serpentine Belt represents a breakthrough in serpentine belt technology with exclusive self-tensioning design. This 3-rib EPDM belt features advanced engineering specifically designed for modern stretch fit drive systems, eliminating the need for traditional belt tensioners.

Innovative Self-Tensioning Technology:

• Specially formulated adhesive locks onto the tensile cord, allowing elongation and stretch without losing tension
• Advanced polyamide (nylon) tensile cord provides optimal strength and flexibility
• Prior to installation, belt is shorter than working length but automatically tensions once installed
• Maintains proper tension over the entire life of the belt for optimum load-carrying capacity

Premium Construction Features:

• Patented EPDM belt ribs extremely resistant to oil contamination, wear, and pilling
• OE exact fit specifications for precise fitment and performance
• 3-rib design with 11mm top width and 771mm (30.35 inch) effective length
• Engineered for water pump and air conditioning accessory drive applications

Important Installation Note: Stretch Fit belts are designed for single-use only and must be replaced if removed. Requires 3mm zip tie for installation (included). Installation instructions provided on Sheet J.
