OS Giken [GT1CD] - GT Single Plate Clutch for Datsun S30 240Z
Note from Sakura Garage: This item is currently listed as Pre-Order. We will contact you with lead times usually within 1-2 business days. If the lead time is unacceptable we will issue a full refund.
Our Grand Touring Clutch is the latest development to our clutch lineup. It retains the technology from our Multi-plate Clutches, but with the addition of our unique floating pressure system to provide a smooth and chatter-free driving experience.
The Grand Touring single plate dampened clutches give some forgiveness to the transmission by absorbing drivetrain shock. The result is a quiet and reliable clutch set. This is ideal for those customers looking for a slightly higher capacity clutch for their showcase vehicle to take it to and from their local concourse gatherings.
****For pure motorsports use or dual purpose vehicles, we recommend starting with our STR clutch lineup.****

OS Giken Tech:
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.
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.
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
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.
