Product Description

The OS Giken NS221-CH51 is an R3C triple plate clutch built for the 1999-2002 Nissan Skyline GT-R R34, representing the highest-capacity clutch in OS Giken's entire lineup. Designed for the RB26DETT's 26-spline transmission, this clutch is engineered from the ground up to handle extreme horsepower and the sustained torque and heat generated by drag racing, drift competition, and circuit racing.

At the core of the R3C is OS Giken's exclusive floating dampened center hub design, which minimizes drivetrain shock during hard shifts and launches while still delivering exceptional holding power - a critical balance for heavily modified RB26 builds pushing well beyond factory power levels. With a torque capacity of up to approximately 1,100 lb-ft, this clutch is built for serious, heavily built applications rather than mild street use.

This kit suits R34 GT-R owners running extreme power builds for drag, drift, or circuit competition who need a clutch capable of reliably transmitting massive torque without slipping or failing under repeated abuse. Installation requires the OEM pilot bearing or bushing along with Nissan's specific flywheel bolts, and OS Giken recommends using their dedicated center alignment tool to ensure the clutch installs correctly given the tight tolerances involved.
