Product Description

HKS has developed a new Transmission Gear Kit with Clutch for ultimate power support for R35 GT-R. We have tested over and over in severe environment with HKS GT1000 spec with slick tires at circuit for time attack.

This is it! The ultimate Transmission Gear and Clutch for the ultimate capability of torque.

CLUTCH PACK: It’s super capacity and total bolt-on design will provide pleasant controllability.

• We have optimized all the parts including the case. We could be able to add one more plate without making the disks or the plates thinner. (Stock: 6 plates, HKS 8 plates)
  With this new and original design, we could have more clutch capacity and could prevent from distortion of the disk by the heat. Also with the new bigger piston diameter can provide 110% more pressing force than the stock without modifying the oil pressure parts.
• Changed design of the inner oil seal that has 170% stronger pressure-resistant than the stock seal.
• Changed thrust needle bearing to the ball bearing for better support for the highly tuned engine’s high RPM.(Tolerant RPM: 8500rpm)
• The new design provides 175% more transmission torque capacity than the stock and 300% stronger than the stock. (HKS test data)
• It’s a bolt-on clutch pack product which is assembled and tested.
• This is the ultimate clutch pack which can support more than 1000PS and at the same time, can drive smoothly for the parking by using the adequate material for the clutch disk that produce perfect μ characteristics.

TRANSMISSION: It’s super strong which has high level of reliability and performs even great in the street.

• We have optimized layout design of the transmission including each plate. This optimization brings a wider cog size which results in the absolute strength compare to other products.
• The stock aluminum plates might distort at a high output and could cause the breakage of the cogs because of the clearance change for the gear. However HKS plates are made of very strong steel material which will have 3 times stronger than the stock.
• We have rigid center portion with the sandwich plate structure and also made special steel front cover. With this new design let you have a stronger bearing supporting strength and also will have gear’s its 100% performance.
