Founded in 2014, our company proudly carries on Detroit’s legacy of automotive innovation by producing high-quality OEM replacement parts that raise the bar for durability and reliability. What started as a focused effort to improve a few failure-prone components has grown into a trusted name in the industry.

Our breakthrough began with heavy-duty metal door handle upgrades—designed to outlast and outperform the originals. That success laid the foundation for a rapidly expanding catalog of premium replacement parts, now covering hundreds of SKUs.

Today, we continue to push the boundaries of excellence, extending our expertise well beyond door handles to meet the evolving needs of modern drivers. Every part we make is engineered to enhance performance, extend vehicle life, and earn your trust—mile after mile.

From DIYers to Automotive Experts
At T1A, we started just like many of you - passionate DIYers who know the pride that comes from fixing, upgrading, and maintaining our own vehicles. That hands-on spirit, rooted in American values and a love for the open road, became the foundation of our brand.

What began in garages and driveways grew into a team of automotive enthusiasts and experts on a mission to transform the aftermarket experience. We believe high-quality auto parts should be both affordable and accessible. That’s why we deliver the same premium-grade components used by leading automotive brands - directly to your door - at a fraction of the cost.

We’re here to help you save time, money, and frustration, while making the parts-buying process easy, convenient, and even enjoyable. Because working on your vehicle should feel just as rewarding as driving it.
