The NS221-DH5 is an OS Giken R4C Series quad plate clutch kit specifically engineered for the Nissan Skyline R34 GT-R (BNR34) with RB26DETT engine. The R Clutch line-up is OS Giken's highest capacity clutch, designed for vehicles with substantial increases in engine power, featuring a unique floating center hub design built to withstand transmission shock from high-powered racecars.

Key Features:

• 215mm quad disc clutch with aluminum cover and center hub
• Capable of handling up to 1400 lb-ft of torque
• Can easily handle over 1000 hp with the billet aluminum clutch cover
• Redesigned diaphragm spring leverage mechanism provides higher clutch disk pressure while reducing pedal effort
• Ventilation holes reduce heat and allow friction plate dust to exit, increasing reliability
• Includes corresponding performance flywheel for maximum performance

This clutch is commonly found in competition drift and drag vehicles as well as Dakar Rally type vehicles. Despite its decreased diameter, the clutch allows for extremely efficient power transfer and improved engine response.
