ACDelco 6K392SF Stretch Fit V-Ribbed Serpentine Belt 6-Rib EPDM

The ACDelco 6K392SF is a Stretch Fit V-Ribbed Serpentine Belt engineered for the accessory drive system. This 6-rib EPDM belt uses stretch fit technology, allowing it to self-tension on the pulley system without the need for an automatic belt tensioner or manual tension adjustment — eliminating additional hardware and simplifying servicing.

Constructed from a high-quality EPDM rubber compound reinforced with a nylon tensile cord, this belt delivers excellent resistance to heat, ozone, oil, and wear for long-lasting durability under demanding conditions. The Multi-V ribbed profile ensures efficient, smooth, and quiet power transfer to engine accessories such as the alternator, water pump, air conditioning compressor, and power steering pump.

Key Features:

• Stretch Fit Design — self-tensioning technology eliminates the need for an automatic tensioner or manual adjustment
• 6-Rib Multi-V Profile (K cross section) for efficient power transmission and reduced noise and vibration
• EPDM Rubber Construction — resists heat, ozone, wear, and contamination for extended service life
• Nylon Cord Reinforcement — provides superior tensile strength and flexibility under load
• OE-Quality Fit — meets original equipment specifications for precise fitment
• Single-Use Design — must be replaced rather than reinstalled once removed; a special installation tool is required
• Effective Length: 39.22 in. (996 mm) | Outside Circumference: 39.75 in. (1010 mm) | Top Width: 0.807 in. (20 mm)
