Big Stack Overdrive Shaft and Reaction Plates Kit; Big Stack Overdrive Shaft/Reaction Plates; Incl. BD Overdrive Shaft/Reaction Plate OE-US and OD-Rev;
The BD Big Stack consists of 16 overdrive clutches, made possible with an improved OD shaft with increased spline depth, and two billet QT100 reaction plates. This allows for a 33% increase in mechanical torque holding capacity and a 33% increase in steel thermal mass. The billet QT100 plates reduce clutch coning due to the stiffer material and geometry. The BD Big Stack can be used in conjunction with a Sonnax input drum to allow a 16% increase in apply area. This setup will allow for a 54% increase in mechanical torque holding capacity. An electronic pressure enhancer (1030369) will further increase OD torque holding capacity.
