HKS has just reintroduced the GR6 gear kit & clutch pack assembly for the R35 GTR. The kit will be in limited production, so if interested, please contact us today at 855-800-7150 so we can check availability. The gear kit & clutch is capable of supporting over 1000 HP and is used in the HKS GT1000 Spec car. This is the ultimate gear kit for circuit racing.
Clutch Pack Key features:
- The case has been optimized to allow the fitment of 8 clutch plates (stock is 6) without making the discs or plates thinner.
- Larger piston can provide 110% more pressure force than stock with the same oil pressure.
- Inner oil seal has been redesigned to provide 170% more pressure resistance than stock.
- Thrust needle bearing has been changed to a ball bearing to provide support up to 8500 RPM.
- Clutch kit is 300% stronger than stock and capable of handling 175% more torque than the stock unit.
- Capable of supporting over 1000 HP while still maintaining drivability for the street.
Gear Kit Key features:
- Transmission layout has been redesigned to fit wider cog gears than stock. Stock cog size is 19.5mm while HKS cog size is 24.5mm.
- Upgraded plates that are 3x stronger than stock, preventing distortion that could cause failure in the wider cog gears.
- Ridged sandwich plate and steel front cover give stronger bearing support strength.
- Gear shape has been redesigned to prevent partial cog contact which can cause gear failure, while also reducing noise.
- Gears have been coated using a special surface treatment used in F1 cars to prevent oil film failure.
- Shift fork has been redesigned to be stronger.
- Shafts have been redesigned to use a screw on the end to prevent snap rings from falling off. This creates less press-fit load, which allows for a strong shaft and easier installation.
