618 27 SPLINE INPUT AND HUB
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.
