Aftermarket Auto Parts Made In-House

When you want something done right, you have to do it yourself. Sometimes the part you need just doesn’t exist, so you have to make it yourself. We have a staff full of mechanics who understand this principle all too well. That’s why we got into the business of machining our own parts built to handle our high standards.

You may not have a machine shop like ours, however. That’s why we offer a full line of supplies for fabricating your own solutions.

At Modern Automotive Performance, we have a reputation for high-quality products — we don’t sell things we wouldn’t install on our own cars. The same philosophy applies to our do-it-yourself components and supplies. If you need a simple silicone coupler, sensor bung or 90-degree elbow hose, we’re going to make sure you have the best quality option in your hands. We also offer durable tools that will last through repeated projects, quality chemicals and lubes and high-quality adhesives that can withstand the extreme environment of a high-performance engine.

So what do you need to make? Contact us and tell us what you need. Trust us: Our mechanics and gearheads fight each other to take these kinds of calls, because mechanical ingenuity is addictive. We’ll help you solve the puzzle in your garage and point you to the right pieces.

We want to be your personal pit crew — that’s why we put an unrivaled effort into our customer service, long after a sale is made. We don’t waste time with your order — as soon as it’s placed, our warehouse starts packing it. Our low prices, outstanding shipping rates and generous Loyalty Rewards program help you save money and fund your next project. We love helping automotive dreams become reality, even when those dreams require a solution that would make MacGyver proud.
