Questions & Answers
Is this a genuine original part?
This is a premium quality 4Drive / Aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for heavy-duty commercial fitment and performance.
How do I know if it is compatible?
We recommend checking the 11-tooth pinion count and the 24V rating. If your original unit is a 50MT Delco style and your cross-reference part number appears in our list, it is a guaranteed fit.
Can this replace a 40MT starter?
In many high-torque applications, the 50MT is used as a heavy-duty upgrade to the 40MT. However, the 50MT is physically larger and heavier; please ensure you have the required clearance and mounting space in your engine bay.
Note: Please verify your original part number against the references above before purchasing. This is a heavy-duty industrial unit (approx 36kg).
