Stretch Poly V-Belts

Top DriveTM Belts are built to the highest standards from the best materials available, using state-of-the-art manufacturing processes, and conforming to international standards such as BS3790, JIS, RMA and DIN.


  • Stretch Poly V-Belts are a special version of Poly-V Belts, which have been specified by the OE manufacturer for greater elasticity — as required by that engine’s belt drive layout.
  • Stretch belt drive design eliminates the need for an automatic tensioner, minimizing the mass of the drive system.
  • Capable of transmitting power through the top surface of the belt.
  • Excellent performance in difficult conditions like cold start, extreme moisture, and high dynamic excitation.
  • Capable of absorbing high dynamic stress load.
  • Range: 22″ – 125″
  • Applications: Fan, alternator, AC compressor water pump, and power steering drive.
