A-Premium Serpentine Belt 7-Rib 83.39 in — K-Section OEM-Fit, EPDM Reinforced

A-Premium's 7-rib serpentine belt (83.39 in effective length) is an OEM-fit replacement designed to restore accessory drive function on select Toyota, Land Rover and Audi models.

This replacement belt is engineered to match original equipment geometry and routing so it installs cleanly and keeps drive accessories — alternator, power steering, A/C compressor and water pump — running smoothly. Built from polyester cord reinforced EPDM rubber, the belt resists oils, heat and abrasion and is sized to fit several popular vehicle families that use the K cross-section 7-rib layout.

Which vehicles will this belt fit?

The A-Premium 7-rib belt is manufactured as a direct OEM replacement for many gasoline-powered Toyota trucks and SUVs and certain high-performance imports. Verify your engine type and OEM reference before ordering to ensure compatibility.

• Toyota Tacoma (2005–2015) 4.0L gas engines
• Toyota 4Runner and FJ Cruiser 4.0L gas variants
• Toyota Tundra 4.0L gas models
• Also cross-compatible with some Land Rover Range Rover and Audi A8 Quattro W12 6.3L applications — check OE numbers

What are the belt’s key dimensions and materials?

This belt follows the K cross-section standard and delivers the length and rib count required for the specified accessory drives. The construction balances flexibility with tensile strength to maintain correct tension and reduce unwanted noise.

• Effective length: 83.39 inches; outer circumference approximately 84.03 inches
• Rib count: 7 ribs in a K cross-section profile
• Core: polyester cord for tensile stability
• Cover: industrial-grade EPDM rubber for chemical and heat resistance

How does this belt improve reliability and reduce noise?

Precision molding and matched OEM geometry keep the belt tracking accurately on pulleys, which reduces vibration and startup squeal common with worn or mismatched belts. The EPDM compound resists oil and contaminants that accelerate cracking, extending service life under heavy loads and hot conditions.

• Stable tensioning reduces slippage and engine accessory chatter
• Oil- and heat-resistant material prevents premature cracking and shredding
• Designed to minimize startup squeak when installed with healthy tensioner and idler pulleys
• Durable construction supports high-load accessory operation

Which OEM part numbers does it cross-reference?

Compare these original equipment references to confirm fitment before purchase. Matching an OEM code is the most reliable way to ensure the belt suits your vehicle.
