Roush, Edelbrock, Chevrolet and More

Roush Engines

Combining engineering with racing, Roush founded Roush Performance Engineering in 1976 and began selling high-performance engine designs to the world of motorsports. His racing team's ability to win and a brilliant solution-oriented approach to building engines earned Roush a reputation associated with excellence.

Edelbrock Engines

Edelbrock engines are known for research and development, manufacturing, and state-of-the-art testing facilities. Racing enthusiasts have called the Edelbrock manufacturing approach "the most state-of-the-art" in the United States. Founder Vic Edelbrock Sr. bought his first project car, a 1932 Ford Roadster, and designed a specialty engine and intake manifold that instantly became a sensation in the world of "hot rods" and racing.

Chevrolet Engines

Chevrolet Performance began engineering high-performance crate engines 50 years ago and today continues to manufacture new horsepower focused engine designs with a distinctly American sound. Chevrolet offers full crate engine drop-in kits to help high-performance car drivers get back to leading the pack fast.

What Our Customers Are Saying

Brought my vehicle in thinking I had a tie rod problem which would be expensive but thanks to Ronsicks Auto they checked out my vehicle and found it was not the tie rods but something different. They saved me $500 + in repairs. I like their honesty and prompt service. They have my business going forward. The staff is very professional and polite.

Had my car in for a state inspection and to find the source of a squeak in the rear of the car. I was told that a strut was the source of the noise & to take it back to whoever did the installation because it should still be under warranty. Very honest workers.
