Questions & Answers

Is this a genuine original part?

This is a premium quality 4Drive aftermarket replacement part, manufactured to meet or exceed original Delco Remy standards for performance and fitment.

What does "12:00 Clocking" mean?

Clocking refers to the position of the wiring harness plug relative to the main mounting bolt when looking at the back of the alternator. 12:00 means the plug is directly opposite the bottom mounting foot.

Can this be used for 1-wire systems?

This specific unit is configured as a standard 3-wire 10SI. While it can be converted with a self-exciting regulator, we recommend checking your specific wiring requirements before installation.

Note: Please verify your original part number and clocking position against the references above before purchasing. For expert support, contact 4Drive.
