Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance in agricultural environments.

How do I know if it is compatible?

We recommend checking your current alternator for the part number 406015A1 or 11.201.952. Note that some MTX models use an 8-groove serpentine pulley; if your tractor uses a flat multi-rib belt, please contact us at 4Drive for the Bosch-style equivalent.

Can this replace a 95A version?

Yes, this 120A unit serves as a high-capacity upgrade for the 95A versions, providing better charging performance for tractors equipped with extra work lights or air conditioning.
