HKS 24996-AK009 Fine Tune V-Belt 4PK925 A/C Belt for 1989-1994 Nissan Skyline GT

Vehicle Fitment

• 1989-1994 Nissan Skyline GT-R (BNR32, AWD, RB26DETT 2.6L Twin-Turbo I6) - A/C Belt
• 1989-1994 Nissan Skyline GTS-T (HCR32, RWD, RB20DET 2.0L Turbocharged I6) - A/C Belt
• 1989-1994 Nissan Skyline GTS4 (BNR32-based, AWD, RB20DET 2.0L Turbocharged I6) - A/C Belt

Fitment Notes

• Belt size: 4PK925 - fits the A/C compressor belt position on all BNR32 R32 Skyline variants with stock pulleys
• Compatible with both standard and HKS Crank Damper Pulley configurations on the BNR32 chassis
• This belt covers the A/C compressor position only - a complete R32 GT-R Fine Tune V-Belt kit also requires: fan/alternator belt 24996-AK005 (4PK880) and power steering belt 24996-AK010 (4PK950)
• Belt back face is blue with the HKS logo - colored nylon fabric used for fade resistance
• Does not fit R33 or R34 Skyline A/C belt position - see HKS 24996-AK008 (4PK910) for those applications

Features

• EPDM (Ethylene Propylene Diene Monomer) construction - selected for superior durability in the high-temperature engine bay environment of the RB26DETT and RB20DET
• High temperature durability rated at 4 times greater than OEM specification
• Low temperature durability rated at 10 times greater than OEM - maintains flexibility and grip during cold-start conditions
• Wear and abrasion resistance improved by 30% compared to OEM
• 17% lighter than the OEM equivalent belt - reduces rotating accessory drive mass
• Aramid core wire - same specification as OEM - provides high rigidity and reliable power transmission to the A/C compressor
• Short fiber mixture in rib rubber improves performance over previous belt construction
• Anti-sound properties reduce belt squeal; good friction tolerance eliminates need for excessive belt tension

Product Description

The HKS 24996-AK009 is a 4PK925 Fine Tune V-Belt engineered for the A/C compressor belt position on the R32 Nissan Skyline GT-R (BNR32), GTS-T (HCR32), and GTS4 variants. Built from EPDM rubber with an aramid core wire and short fiber rib rubber construction, this belt delivers four times the high-temperature durability and ten times the cold-temperature performance of the OEM belt, while reducing rotating mass by 17% and improving wear resistance by 30%. These specifications make it the standard choice for R32 owners performing a thorough engine bay belt refresh, particularly in builds where the twin-turbo RB26DETT generates sustained elevated heat.

The signature blue back face with the HKS logo provides a clean, well-coordinated engine bay appearance alongside other HKS components, while color-fade-resistant nylon fabric maintains the finish over time. This belt fits the BNR32 A/C position with both stock pulleys and the HKS Crank Damper Pulley, making it a flexible upgrade regardless of pulley configuration. For a complete R32 GT-R belt set using HKS Fine Tune V-Belts, this A/C belt (4PK925) is paired with the fan/alternator belt 24996-AK005 (4PK880) and power steering belt 24996-AK010 (4PK950).
