PowerBastards Product FAQ
Will this fit my Chevrolet Silverado 2500 HD ?
Yes! Our 370A High Output alternator for the Chevrolet Silverado 2500 HD is built as a direct-fit replacement. It is designed to use the factory mounting points and original style electrical connections unless noted otherwise.
Will your 370A high output alternator damage the computer in my Chevrolet Silverado 2500 HD ?
Our high output alternators are designed to work seamlessly with your vehicle’s electrical system. Our alternators are fully compatible with your Chevrolet Silverado 2500 HD. They meet and exceed OEM performance specifications. In fact, you can install our high output alternator in a completely factory Chevrolet Silverado 2500 HD and your new alternator will operate exactly as designed.
Do I need a shorter belt ?
Your factory belt should work just fine with the new alternator, if it’s in good condition and was the correct length to begin with.
If you have any questions during the install, feel free to reach out.
Do I need the BIG ZERO Wire Kit ?
For high output alternators, upgraded charge wiring is strongly recommended. The BIG ZERO kit is designed to safely carry the additional amperage from the alternator to the battery without adding unnecessary extra grounds that can interfere with modern vehicle charging systems.
Do you have a higher amp model ?
Our 370A High Output alternator is the highest reliable amperage available for this Chevrolet Silverado 2500 HD. Pushing the alternator beyond its reliable operating limits can compromise performance, increase noise, and reduce long-term durability. Our high output alternators are engineered and calibrated to deliver maximum usable output across the entire engine RPM range while maintaining reliable, quiet operation for years to come.
Will too many amps damage my car ?
No. By design, your vehicle only uses the amperage it needs. A higher output alternator provides additional charging capacity when demanded by added accessories and electrical loads.
