About Powerhouse

Power on the first turn.

Powerhouse Supply is an Oklahoma company built on a simple idea: when you turn the key, it should start. We supply auto electrical parts, starters, alternators, and the components that keep vehicles running, chosen for fit and reliability so you are not guessing.

Why Powerhouse

The name says it. In every cell of the body, the powerhouse is what makes energy. In every vehicle, the electrical system is what brings it to life. That is our lane, and it is all we do. We keep the catalog focused, the fitment accurate, and the shipping fast.

How we work

• Ships from USA. Every order ships from the United States with tracking.
• Fits / compatible with OEM. We list the OEM numbers a part matches so you can order with confidence. The compatibility note is a guide, so please confirm the OEM number and application match your vehicle before you install. Electrical parts that have been installed or used cannot be returned. Not sure? Send us your vehicle details and we will help you check before you buy.
• Backed by warranty. Our starters and alternators carry a 1 year limited warranty that starts on the delivery date. Read what is covered, what is not, and how to file a claim in our Return and Refund Policy before you buy.
• Real help. A person answers your questions about fit, specs, and orders.

Our promise

We would rather help you get the right part the first time than sell you the wrong one twice. Send us what you are working on and we will point you to the part that turns it over on the first try.

Our policies

How we ship, our 30 day returns, the 1 year limited warranty, our Terms of Service, and our Privacy Policy are all posted in full. Please review them before you order so you know how we ship, how returns and warranty claims work, and how we handle your information. Questions about fit, an order, or a policy?
