HKS 27006-AN010 Transmission Gear Clutch Pack Kit for GT-R - R35

The HKS 27006-AN010 Transmission Gear Kit with Clutch Pack is an extensively engineered drivetrain upgrade developed specifically for the Nissan R35 GT-R. HKS validated this system through rigorous testing under extreme conditions using the HKS GT1000 specification vehicle equipped with slick tires in circuit time attack environments, ensuring it can withstand the demands of both high-performance motorsport and street use.

Clutch Pack Features:

• Upgraded from 6 stock clutch plates to 8 HKS plates without reducing individual disk or plate thickness — achieved through a fully optimized case design
• New larger piston diameter delivers 110% more clamping force than stock without requiring any oil pressure system modifications
• Redesigned inner oil seal offers 170% greater pressure resistance compared to the OEM seal
• Thrust needle bearing replaced with a ball bearing for superior high-RPM support, with a tolerance rating of 8,500 RPM
• Delivers 175% more transmission torque capacity than stock and 300% greater overall strength (per HKS internal test data)
• Fully assembled and tested bolt-on clutch pack — no partial assembly required
• Capable of supporting over 1,000 PS while maintaining smooth, controlled engagement at low speeds using purpose-selected clutch disk materials

Transmission Features:

• Optimized internal layout including individual plate design, resulting in a wider cog profile for maximum strength and durability
• HKS plates are manufactured from high-strength steel, replacing the OEM aluminum plates that are prone to distortion and cog breakage under high-output conditions — providing approximately 3x the strength of stock
• Sandwich plate structure with a rigid center section and a specially fabricated steel front cover improves bearing support and ensures full gear performance under load

The HKS 27006-AN010 is the definitive transmission and clutch solution for R35 GT-R builds targeting maximum power output without sacrificing drivability. As a complete bolt-on assembly, installation is straightforward with no custom fabrication required.
