Product Details

The Roadmax Automotive V-Ribbed Belt (Standard) line is positioned for budget-conscious maintenance where a reliable replacement belt is needed for everyday driving. This belt uses EPDM material, which is commonly specified for accessory drive systems, and polyester cord reinforcement to help maintain belt form and tracking. The 6-rib, K-section profile and listed dimensions make 6K863AP a direct-reference option for vehicles that call for this size.
