Roadmax 6K735AP Serpentine Belt Overview

The Roadmax 6K735AP is an automotive V-ribbed belt built with EPDM rubber and polyester cord for standard accessory drive service. It is a practical choice for drivers who want dependable belt replacement without moving to a premium-performance belt.

Product Details

Roadmax positions the 6K735AP as a standard replacement belt for budget-conscious repairs where quality matters and premium belt performance is not required. The EPDM belt material is commonly used in modern accessory drive systems, while the polyester cord helps support stable belt operation under normal engine accessory loads. If you are replacing a worn serpentine belt on a Porsche 911, Mercedes-Benz SLK230, or Audi A6, this part number provides a direct reference point for matching the correct rib count and length.

This part cross-references Gates K060735 and Dayco 5060735 for the same application.

What This Belt Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing belt
• Loss of belt tension from age-related stretch
• Accessory drive noise on vehicles with power steering and air conditioning
• Routine maintenance replacement on older belt-driven systems
