A-Premium Serpentine Drive Belt 6-Rib 87.57 in EPDM K-Section — Heavy-Duty Replacement

A-Premium's serpentine belt is a 6-rib, 87.57-inch EPDM drive belt engineered to replace worn factory belts and restore accessory drive reliability.

This heavy-duty replacement belt is designed for vehicles that require a K-section, six-rib routing with an effective length of 87.57 inches and an outside circumference of 88.135 inches. Built from EPDM compound with polyester cords, the belt balances flexibility and tensile strength to resist cracking, oil contamination, and high-temperature wear—making it a practical option for many domestic and imported models. Before fitting, check your tensioner and accessory pulleys to ensure correct alignment and long service life.

Which vehicles will this 87.57-inch belt fit?

The A-Premium 6-rib belt fits a variety of cars, trucks, and SUVs that specify a K-section belt of these dimensions. Fitment covers select Chevrolet and GMC P-series trucks, Jeep Wrangler JK generations, several Mercedes-Benz models across C, GLK, ML and GLE lines, and some Mitsubishi Raiders. Always confirm part compatibility with your vehicle's year, engine, and accessory options (for example, air conditioning or alternator rating).

• Chevrolet P30 1996 V8 5.7L (without A/C; with 124A alternator)
• GMC P3500 1996 V8 5.7L (without A/C; with 124A alternator)
• Jeep Wrangler JK models 2012–2018
• Mercedes-Benz C280 (W202 1994–1995), multiple ML/GLK/GLE models (selected years)
• Mitsubishi Raider 2006–2007

How is this belt constructed to handle heat and contamination?

This serpentine belt uses EPDM elastomer for the main body and polyester cord reinforcement for strength, providing enhanced resistance to environmental and chemical stressors. EPDM maintains flexibility at high and low temperatures and resists degradation from oils and road contaminants. The reinforced cord resists stretching, keeping tension consistent over time.

• EPDM compound resists cracking and ozone deterioration
• Polyester cords provide dimensional stability and longevity
• Precision top width (0.807 in) and rib count ensure correct pulley engagement

What performance benefits can I expect after replacing my belt?

Installing this A-Premium belt restores proper accessory drive tension and alignment, which reduces squeal, vibration, and premature wear of pulleys and tensioners. With correct installation it improves reliability for alternator, power steering (when present), water pump, and AC compressor circuits. It’s engineered to meet or exceed fitment specifications for a straightforward swap when the belt size matches your vehicle’s requirement.

• Reduced noise and vibration from improved rib fit and tension
• Better resistance to oils and heat for longer service intervals
• Tool-free friendly installation when tensioner inspected and serviced

How should I prepare my vehicle before installing this replacement belt?

Before installation, examine the belt routing diagram, inspect all pulleys, and test the tensioner for smooth operation and correct spring tension. Replace any worn idlers, pulleys, or tensioners; a new belt on degraded components risks premature failure. Clean pulley grooves and remove frayed remnants of the old belt to ensure proper seating.

• Verify vehicle-specific routing and confirm K-section, 6-rib sizing
• Inspect and, if necessary, replace tensioner and idler pulleys
• Check alternator and accessory mounting for axial play before fitting

Who is this for: This A-Premium 87.57-inch, 6-rib serpentine belt is intended for DIY mechanics, independent shops, and fleet maintenance teams needing a durable replacement for compatible Chevrolet, GMC, Jeep, Mercedes-Benz, and Mitsubishi vehicles. It suits owners who want an EPDM, polyester-reinforced belt offering improved resistance to oil and heat, and those who will service or confirm the condition of the tensioner and pulleys before fitting. A one-year unlimited-mileage guarantee backs the belt's workmanship for added peace of mind.
