Key Features：
✔ Vehicle-Specific Fit: 6PK1390 Designed specifically for the Ford F-150 3.5L (2011+)
✔ Premium EPDM Rubber: Superior resistance to heat, ozone, cracking and wear for extended service life
✔ Aramid Reinforced: High-strength aramid tensile cords minimize belt stretch under heavy loads
✔ Back Fabrication: Integrally Vulcanized Stretch Knit Fabric Cover
✔ Design Intent: Engineered strictly for heavy-duty service
Why Choose This Belt：
Nearly all mid-grade serpentine belts adopt 90° cross-woven canvas matched with low-EPDM rubber. The rigid woven surface builds tension during repeated bending and cracks quickly.
Our belt carries three premium configurations:
1. Integrally vulcanized stretch knit back cover with single-direction twill. Full dipping bonds fabric and rubber into one solid piece, a craft limited only to top-tier brands.
2. Formulated with 20% higher EPDM than standard belts to resist heat and ozone aging.
3. Aramid tensile cords eliminate stretching under heavy-duty torque.
Comparable name-brand belts retail for no less than $32–36 USD, and most small aftermarket suppliers skip this costly process to cut expenses. Thanks to our robust supply chain and mature manufacturing process, we hold cost advantages. We price this flagship item with thin profit margins solely to build brand recognition and win bulk customers. This value combination is extremely hard to source elsewhere.
