A-Premium Serpentine Belt 6-Rib 88.3 in — EPDM K-Section, OE Fit for V6/V8 Engines

The A-Premium 6-rib serpentine belt (88.3 in effective length) is a direct-fit replacement belt that powers your engine accessories with OEM-equivalent materials and precise dimensions.

If your vehicle uses a single multi-rib drive belt to operate the alternator, water pump, fan clutch and A/C compressor, this A-Premium serpentine belt is built to match factory sizing and restore proper accessory drive function. Constructed from EPDM rubber reinforced with polyester cords and a K-section cross profile, it fits many Ford, Jeep, Toyota, Dodge, Mercedes-Benz and Chevrolet applications without trimming or alteration. The design emphasizes long life, heat and oil resistance, and stable tension so accessories run smoothly after installation.

Which vehicles will this 88.3-inch, 6-rib belt fit?

This belt covers a wide range of domestic and import models that originally used a 6-rib K-section belt at 88.30 inches effective length. It fits factory accessory layouts for many V6 and V8 engines across trucks, SUVs and cars—no modification required when matched correctly.

• Ford: Explorer 1997 4.0L V6; Fusion 2006–2009 2.3L; Ranger 1997–2006 3.0L (AC models)

• Also fits select Mercedes-Benz, Chevrolet, Dodge, Ram, Jeep Wagoneer/Cherokee and vintage models listed in the reference numbers.

How does this belt’s construction affect durability and noise?

The belt uses EPDM compound with a high-strength polyester tension cord to resist cracking, heat aging and oil exposure common in engine bays. Its dimensional control and K-profile ribs help maintain consistent tension, which reduces slip, vibration and squeal compared with worn belts.

• EPDM material improves resistance to high temperatures and ozone compared with older rubber formulations.
• Polyester cord offers strong tensile stability to hold accessory alignment under load.
• Precision sizing lowers the chance of chirp or squeal after replacement when the tensioner and pulleys are serviceable.

What specifications and reference numbers should I check before buying?

Confirm that your vehicle calls for a 6-rib K-section belt with an effective length near 88.30 inches and a top width around 0.807 inches. Cross-reference the listed part references to your factory number to ensure interchangeability.

• Effective length: 88.30 in; outside circumference: 88.870 in; ribs: 6; top width: 0.807 in.
• Belt material: EPDM; cord: polyester; cross section designation: K.
• Reference numbers include K060882 and several OEM equivalents (examples: 12583316, 0129970892, 074260849L).

Can I install this belt myself and what should I inspect during replacement?

Yes—this belt is sized to match factory routing and supports DIY installation for mechanically inclined owners. Always inspect the tensioner, idler pulleys and accessory bearings; replacing a worn tensioner or misaligned pulley prevents premature belt wear.

• Check tensioner travel and spring strength before installing the new belt.
• Inspect pulleys for grooves, roughness or lateral play; replace faulty pulleys if needed.
• Use the vehicle’s belt routing diagram and confirm correct rib alignment across all pulleys.
