A-Premium Serpentine Belt 7-Rib 61.02 in — EPDM Replacement for Lexus & Toyota V6, K-Section

The A-Premium 7-rib serpentine belt (61.02 in) is a direct-fit EPDM replacement designed to restore reliable accessory drive function on select Lexus and Toyota V6 gasoline engines.

This replacement belt is built from EPDM compound with polyester cords and a K-section cross‑section engineered for correct tension, alignment, and long life. It replaces factory-style belts on many Lexus and Toyota V6 gasoline vehicles, offering improved resistance to oils, heat, and contaminants. The specification set—61.02" effective length, 7 ribs, 0.947" top width—matches OEM dimensions so pulley geometry and belt routing remain correct.

Which vehicles and engines will this belt fit?

The A-Premium belt is intended for gasoline-powered Lexus and Toyota V6 models from several recent model years. It fits engines that originally used a 7-rib K-section belt with the listed effective length and outside circumference. Always verify fitment with your vehicle's year, model and engine code before purchasing.

• Compatible Lexus: ES350, GS300/GS350, IS250/IS300/IS350, RC300/RC350, RX350 (specific year ranges apply)
• Compatible Toyota: Avalon, Camry, Highlander, RAV4, Sienna, Venza (V6 3.5L gasoline engines)
• Not compatible with hybrid or electric drivetrains—gasoline V6 engines only

How does the A-Premium belt resist wear and environmental damage?

Manufactured from EPDM rubber and reinforced with polyester cords, this belt is formulated to tolerate common under‑hood stresses. The material combination helps resist cracking, oil contamination, and heat-induced degradation, delivering a longer usable life than older synthetic compounds.

• EPDM compound minimizes ozone and heat cracking
• Polyester cords preserve tensile strength and maintain proper tension
• Precision molding reduces rib deformation and prevents slipping

What are the exact technical specs and reference numbers?

The belt follows industry K-section geometry with precise outside circumference and effective length measurements to ensure correct belt wrap and pulley contact. Several cross-reference part numbers help confirm compatibility when replacing factory belts.

• Effective length: 61.02 inches; Outside circumference: 61.63 inches
• Rib count: 7; Top width: 0.947 inches; Cord: polyester
• Cross references: K070610, 7PK1550, 90916A2019, 99367C1550, 99367K1550

How should I install and maintain this serpentine belt?

Installation is straightforward if you follow standard belt routing and tension procedures, but check the condition of the tensioner, idler pulleys, and accessory bearings before fitting the new belt. A worn tensioner or sticky pulley can shorten belt life even when the replacement is high quality.

• Inspect and, if necessary, replace the tensioner and idler pulleys before installation
• Use proper belt routing diagrams and a tension gauge or manufacturer torque specs
• After installation, run the engine and verify quiet operation and correct alignment

Who is this for: The A-Premium 7-rib 61.02" serpentine belt suits DIY mechanics, independent shops, and fleet managers who need a durable, OEM-dimension replacement for select Lexus and Toyota V6 gasoline models. It’s appropriate for anyone replacing a worn or damaged accessory drive belt who wants EPDM material, polyester reinforcement, and a one-year unlimited-mileage warranty for added confidence.
