Suncoast's 618-27 Proprietary 27 spline input shaft (requires custom torque converter) has proven itself time and time again. This shaft takes an extreme amount of abuse where stock sized billet input shafts simply cant stay in one piece.
Our optional 27-Spline Stator Support is designed to be used with this Input Shaft & Hub and is machined to exact tolerances to ensure true drop-in replacement.
For 48RE, 47RE, & 47RH transmissions only: this kit will only fit Ram 5.9L Cummins with 48RE, 47RE, or 47RH transmissions. Please verify your truck's transmission type before ordering.
Requires 27-spline torque converter & stator support: this kit will require the use of a 27-spline torque converter and SunCoast's 27-Spline Stator Support for installation. The kit will not fit with stock-style 23-spline torque converters or 23-spline stator supports.
