Gates 6PK1856 Serpentine Belt

Gates Premium OE Micro-V Belt 6PK1856

The Gates Premium OE Micro-V Belt 6PK1856 is a serpentine belt built for OE-style fit and construction. It uses EPDM belt material, a polyester cord, and a 6-rib V-ribbed design to match the dimensions and performance requirements of the original drive belt application.

Compatible with select Audi models, including the Audi A6 Quattro, Audi Allroad Quattro, and Audi S4, this belt is specified for vehicles with A/C and for use with a previously installed solution kit only.

Product Details

Gates Micro-V belts are engineered to match OE size, construction, and materials so the accessory drive system can operate with the correct belt geometry.
