HKS 24996-AK019 Fine Tune V-Belt 6PK1790 EPDM Performance Accessory Drive Belt

The HKS Fine Tune V-Belt (24996-AK019) is a high-performance accessory drive belt engineered to replace the OEM 6PK1790 belt. Built with EPDM (Ethylene Propylene Diene Monomer) rubber, this belt delivers superior durability and consistent performance across a wide range of operating temperatures — from cold-start conditions to the high underhood heat generated by modified and tuned engines.

Beyond function, the Fine Tune V-Belt also serves as an engine bay dress-up component. The belt features a distinctive blue back face with the HKS logo, complementing other HKS blue engine bay components such as intake hoses for a coordinated, professional appearance. The HKS logo, product name, and belt length are printed directly on the belt for easy identification.

Key Features:

• EPDM rubber construction — provides better durability and performance in both high-heat and cold-weather conditions with improved friction tolerance
• Short fiber mixture in rib rubber — improves performance over previous belt generations
• Lightweight design with good friction tolerance — excess belt tension is not required, reducing stress on accessory pulleys and bearings
• Anti-sound properties — reduces belt squeal for a quieter engine bay
• Colored nylon fabric construction — provides excellent resistance to color fading over time
• Blue with HKS logo — distinctive engine bay appearance that coordinates with other HKS components
• Replaces OEM belt: 6PK1790

The HKS Fine Tune V-Belt is an ideal upgrade for enthusiasts seeking a performance-oriented replacement belt that combines daily reliability with an aggressive, tuner-focused engine bay aesthetic.
