HKS 24996-AK004 Fine Tune V-Belt 4PK875 Fan Belt for Nissan Skyline GT-R R33/R34

Vehicle Fitment

• 1995-1998 Nissan Skyline GT-R (BCNR33, RWD, RB26DETT 2.6L Twin-Turbo I6) - Fan Belt position
• 1999-2002 Nissan Skyline GT-R (BNR34, RWD, RB26DETT 2.6L Twin-Turbo I6) - Fan Belt position
• 1989-1994 Nissan Skyline GT-R (BNR32, RWD, RB26DETT 2.6L Twin-Turbo I6) - Fan Belt position when used with HKS Damper Pulley Kit (P/N: 24998-AK002 or 24998-AK003)
• 1989-1999 Toyota MR2 (SW20, RWD, 3S-GTE 2.0L Turbocharged I4) - A/C Belt position only

Fitment Notes

• Belt size: 4PK875 - fits the fan/auxiliary belt position on R33 and R34 GT-R with stock pulley configuration
• For BNR32 (R32) GT-R applications, use of HKS Damper Pulley Kit (24998-AK002 or 24998-AK003) is required - this belt does not replace the fan belt on an R32 with stock pulleys
• On the Toyota MR2 SW20, this belt fits the A/C compressor belt position only - not the alternator or power steering positions
• Additional HKS Fine Tune V-Belt part numbers are required for power steering and A/C positions on the R33/R34 GT-R - confirm full belt kit requirements before ordering

Features

• EPDM (Ethylene Propylene Diene Monomer) construction - the same advanced material used in high-performance and motorsport belt applications
• High temperature durability rated at 4 times greater than OEM belts - engineered for the elevated engine bay temperatures of tuned turbocharged platforms
• Low temperature durability rated at 10 times greater than OEM - maintains flexibility and performance in cold-start and winter conditions
• Wear and abrasion resistance improved by 30% over OEM specification
• 17% lighter than the OEM equivalent belt - reduces rotating mass and accessory drive load
• Good friction tolerance properties allow proper tension without over-tightening
• Anti-sound properties reduce belt squeal under load and during cold starts
• Improves engine bay appearance - a recognizable engine dress-up upgrade in the RB26 community

Product Description

The HKS 24996-AK004 Fine Tune V-Belt is a 4PK875 fan/auxiliary belt engineered using EPDM (Ethylene Propylene Diene Monomer) material - the same technology found in high-performance motorsport belt applications. Compared to the OEM rubber belt, the Fine Tune V-Belt delivers four times the high-temperature durability and ten times the low-temperature performance, addressing the demanding conditions of the RB26DETT engine bay where heat soak from twin turbochargers and sustained high-speed operation can degrade standard belts prematurely. The belt also reduces rotating mass by 17% versus OEM and improves wear resistance by 30%, contributing to a more efficient accessory drive system.

On the R33 and R34 GT-R, this belt fits the fan belt position with the stock pulley setup. R32 GT-R owners require the HKS Damper Pulley Kit (24998-AK002 or 24998-AK003) before this belt can be used. For Toyota MR2 SW20 applications, the 4PK875 size fits the A/C compressor belt position only. A full belt kit for the R33/R34 GT-R typically includes multiple HKS Fine Tune V-Belts covering the fan, power steering, and A/C positions - confirm the complete set of required part numbers for your application before ordering.
