Poly-V belts

ram automotive belts and hoses

ram poly-v belts are designed for quieter performance and feature treated, high-strength cords that extend belt life and prevent shock load failure.
Our poly-v belts provide optimal performance and have been used by one of the winning teams at Le Mans in recent years.

Each ram fan belt also features the following:

  • Specially treated high strength cords to maintain tension and prevent shock load failure
  • Reduction in operating noise of up to 15 dB
  • Fibre reinforced cushion section supports the cords and minimises pully wear.
  • Oil and abrasion-resistant backing fabric
