Superior Performance for Your 1975-1980 Chevrolet G30

Introducing the Top Pick 1975-1980 Chevrolet G30 V8 6.6l 12si High Output Alternator Massive 35% Savings [gUzLVNjW], a direct-fit solution designed to boost the electrical output of your classic vehicle. This high-output alternator is engineered to provide increased charging capacity, ensuring your vehicle's electrical systems operate smoothly and efficiently. With its direct fitment, it's easy to install, requiring no additional modifications to your stock alternator location.

Engineered for Performance and Reliability

The high-output alternator is equipped with a separate adaptor plug, allowing for seamless integration with your factory plug and aftermarket high-output alternator. This adaptable design ensures compatibility and ease of installation. Notably, the included smaller pulley optimizes the alternator's performance by spinning faster, which can enhance its maximum output. However, it does require a 1/2" - 1" shorter belt, which you can find assistance with in our blog article "Need Help Finding Shorter Belt for Your JS Alternators High Output Alternator".

Enhance Your Vehicle's Electrical System

Upgrading to the high-output alternator is an essential step in ensuring your Chevrolet G30's electrical system is up to par. It's recommended to pair this alternator with our Big 3 Wiring Upgrade Kit, which includes 1/0 100% copper wires for optimal performance. This kit is 10% off when purchased with a JS Alternator, and you can enjoy this exclusive offer by using the code BIG3DISCOUNT at checkout. By investing in this high-output alternator and the Big 3 Wiring Upgrade Kit, you can rest assured that your vehicle's electrical system will be powerful, reliable, and ready for any adventure.
