Release Sleeve Assembly for OS Giken Clutch Kit

OS Giken offers push style release bearings for use of OS Giken push-type clutches. These release sleeve assemblies have a special radius taper on the face of the bearing to allow for increased modulation and control over clutch release. This reduces overall effort needed to fully engage/disengage the clutch resulting in a lighter clutch pedal. 

Please note that the OS Giken Release Sleeve Assemblies are designed specifically to work with OS Giken clutches. Use of these bearings with unintended applications may result in failure of clutch components.

Fitment:

  • Nissan Skyline GT-R (R34) - OS 88 Transmission

Product Details:

  • Push Style Release Sleeve Assembly
  • For use with OEM Clutch Fork Design
  • Chemically heat treated for strength and long lasting service live.

Overhaul Kits are meant for the repair and refurbishment of an OS Giken clutch kit. Overhaul kits are not universal fitment and must be specifically order for each particular model of OS Giken clutch.

 

Overhaul Kit A - Includes the follow parts:

  1. Replacement Clutch Friction Disc(s)
  2. Replacement Pressure Plate (not the Aluminum or Steel Cover)

Overhaul Kit B - Includes the follow parts:

  1. Replacement Clutch Friction Disc(s)
  2. Replacement Pressure Plate 
  3. Replacement Clutch Cover (Aluminum/Steel) *Covers are not interchangable*
CLUTCH COVER
Our specially designed clutch cover contains a unique leverage mechanism for the diaphragm spring, resulting in a higher clamping load of the clutch disc(s) while also reducing pedal effort. These diaphragm springs combined with our special OS Giken Release Sleeves provide a much easier to operate clutch.

DISCS
We utilize full face metallic clutch plates to achieve high torque capacity from our clutches. This allows for us to use much softer diaphragm springs to achieve equal or better torque capacity compared to our competitors with substantially less pedal effort.

CLUTCH HOUSING
Integrated ventilation holes reduce heat generated inside the clutch system and allows for friction plate dust to exit outside the clutch system, thus increasing reliability and safety. Both the clutch housing and flywheel are chemically heat treated to handle extreme conditions. Increased power output typically requires more torque capacity(friction) in order to hold. This often leads to more heat being generated

 

FLYWHEEL
Our hardened steel alloy flywheels provide superior durability and life than aluminum flywheels, which also results in quicker and predictable engine response. We develop our own flywheel design to maximize our design and engineering philosophies into a no-compromise, complete clutch assembly.
Our integrated clutch and flywheel packages increase transmission efficiency and engine response. Our clutches and flywheels are built within strict tolerances and crafted using carefully selected materials to provide the highest quality and durability.
