Competition Clutch Lightweight Steel Flywheel Skyline RB20DET RB25DET 2-630T-ST

The Competition Clutch Steel Ultra Lightweight Flywheel (ST) for the RB20 & RB25 Nissan Skyline models with a push type transmission, provides a lighter 12lb. flywheel that helps decrease the moment of inertia compared to the factory 22lb. flywheel. This weight reduction will result in better throttle response and quicker acceleration.

The Competition Clutch ST flywheels are manufactured from 4140 forged steel and are a one-piece design. These characteristics prevent ring gear separation, reduce friction surface warpage, and maintain the rigidity of the flywheel. STs can be resurfaced for long term durability. CCI flywheels are CNC machined and balanced to O.E. specifications.
