The stator in Allison® 1000/2000/2400, 2006-later torque converters is prone to spin on its outer race due to failure resulting from OE serration design. Sonnax stator and outer stator race kit AL-ST-1K replaces stators that have spun on the OE outer race and prevents future rotation.
Sonnax highly recommends replacing assemblies which have not yet failed, especially in units where diesel performance is enhanced.
Redesigned splines are longer and deeper than OE serrations for superior holding power
No machining required
