Constantly Improving!

KTSDI has expanded, now we're even bigger and better equipped to handle all of your needs.

Our new, significantly larger facility is just a few short miles from our old facility in Youngstown Ohio. We've increased staff, increased spare parts selection, increased our service facility and increased our presence in the heavy duty vehicle market!

Our goal is to continue to offer you the same personal experience you've always gotten, we've still got real staff answering the phones, and we make every issue a priority!

Please be sure your records are up to date with our new address!

Helping To Shape The Future

At KTSDI we firmly believe in preparing today’s youth for the challenges of tomorrow. We take an active part in our community and our country’s future by hosting, attending and assisting in numerous STEM (Science, Technology, Engineering, Mathematics) events every year.

If we wait until our country’s youth is in high school or older to begin introducing them to STEM concepts then we’ve waited too long. That’s why we’re trying to make these concepts interesting, engaging and fun for young children. KTSDI, along with a wide variety of other local companies works hard to help shape America’s future by putting tools in the hands of developing youth. We do that by teaching them to change a tire or what renewable energy is, how 3d printing works or what CAD is. We teach the value of engineering principles in everyday life and show not only what jobs are available to them when they’re ready, but expose them to how interesting and fun these jobs can be.

We are proud to have been able to host dozens of local schools, children of all ages, politicians, teachers and businesses and we hope to be able to continue to do so for the foreseeable future.
