BD Diesel 1062035 Big Stack Overdrive Shaft And Reaction Plates Kit

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.
