Using the latest in-belt technology gives the following benefits:

  • Increased durability at high temperatures which can be found in the engine bay of tuned vehicles.
  • Increased performance in cold weather and condition.
  • Lightweight and good friction tolerance properties which means that excess tension is not required while anti-sound properties reduces belt squeal.
  • The lightweight belt provides high-following performance even at a variable rotational speed, and this does not only reduce squeaking sound but also provides high transmission efficiency.

HKS logo, product name, and belt length are printed on the back of the blue 6PK2037 belt.
Simply replacing the OEM belt with this belt can upgrade your current GR86 and BRZ.




EPDM (Ethylene Propylene Diene Monomer) Rubber was selected because of:

  • Better durability and performance in hotter or colder conditions with improved friction tolerance.
  • Much lighter than previous version of belt.
  • Short fiber mixture in rib rubber improves the performance over previous version.
