HKS 27006-AN013 Transmission Gear & Clutch Pack Kit for Nissan GT-R R35

The HKS 27006-AN013 Transmission Gear and Clutch Pack Kit is an extreme-duty, bolt-on upgrade engineered specifically for the Nissan GT-R R35. Developed and validated through rigorous circuit testing under the HKS GT1000 program using slick tires in time attack conditions, this kit is purpose-built to handle power levels exceeding 1000PS while maintaining drivability on the street.

Clutch Pack Features:

• Upgraded from 6 stock plates to 8 HKS plates — achieved through a fully redesigned case without reducing disk or plate thickness
• 110% greater clamping force over stock, delivered by a larger-diameter piston — no oil pressure system modifications required
• Redesigned inner oil seal rated at 170% stronger pressure resistance compared to the OEM seal
• Thrust needle bearing replaced with a ball bearing for improved high-RPM reliability — tolerance rated to 8,500 RPM
• Delivers 175% more transmission torque capacity than stock, with overall clutch strength 300% greater than OEM (per HKS test data)
• Clutch disk material selected for optimal friction characteristics, providing smooth, predictable engagement even at low speeds and during parking maneuvers
• Fully assembled and bench-tested prior to shipment — true bolt-on installation

Transmission Gear Kit Features:

• Optimized gear layout design increases cog width, resulting in significantly higher load capacity compared to competing products
• Gear selector plates machined from high-strength steel — approximately 3 times stronger than the OEM aluminum plates, which are prone to distortion under high-output conditions
• Steel plates eliminate the gear clearance changes that can lead to cog damage under sustained high-power use
• Sandwich plate structure with a reinforced center section and a specially fabricated steel front cover for enhanced bearing support and full gear performance

The HKS 27006-AN013 kit includes the complete Plate T1.0 Set and is the definitive transmission upgrade for R35 GT-R builds targeting maximum output without sacrificing street usability. OEM Reference: R35 GT-R dual-clutch transmission (GR6 transaxle).
