  Fine Tune V Belt

The Engine compartment dress-up part; "Fine Tune V Belt."
Latest technology protects vehicles' conditions while improving engine compartment appearance.


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.
  • * Back face is blue colored with HKS logo.
  • Blue is used in HKS intake hose which is for coordination in the whole engine bay.
  • Colored nylon fabric used for good anti-color fading properties.
  • HKS logo, product name, and belt length are printed on each belt.


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.

  • Button bolts were installed to 24996-AK012 (5PK875) and 24996-AK013 (5PK885) during the test.
  • When using these 2 belts above, a stock V belt may come in contact with a stock alternator adjustment bolt due to an insufficient clearance between them. 
    Using the provided button bolts can prevent abrasion of the V belt.
