Fabric-Backed Belts

Cloyes fabric-backed EPDM belts are designed to withstand the harsh conditions of high-mileage engines, tight routing, and daily driving. When the job calls for quiet operation, long life, and professional reliability — this is the belt you want.

Features & Benefits:

  • Quieter Operation - Reduces noise and vibration common in aging or misaligned systems - especially during cold starts or accessory engagement.
  • Controlled Engagement - Fabric backing helps manage slip and tension changes - ideal for systems with A/C cycling or rapid load shifts.
  • Superior Wear Protection - Reinforced outer layer minimizes abrasion from back-side pulley contact and rough edges.
  • Better Heat Management - Spreads and dissipates heat more evenly across the belt surface, reducing hot spots that can lead to cracking or glazing.
  • Ideal for Older Engines - Compensates for imperfect pulley alignment and worn components - making it a smart choice for retrofits, rebuilds, and high-mileage repairs.
