Roush Performance

Roush Performance is an American automotive company primarily involved in the engineering, development and manufacturing of high performance components for street and competitive racing applications. The company's namesake is automotive mogul Jack Roush, who also owns and operates it. It was founded in 1995 by Roush to provide engineering from racing to street cars.

Aftermarket parts

Roush produces aftermarket performance parts for Ford cars and trucks, mainly the Ford Mustang, Ford Focus, and the Ford F-150 light duty pickup. These special model vehicles are sold to the public through select Ford dealerships. In addition to the high performance business, Roush supplies propane conversions kit for the F-150, as well as for school buses.

Roush is listed as a vehicle "Manufacturer of Record," in that the company modifies Ford F-150, Ford Focus and Ford Mustangs to the extent that they are considered "Roush" vehicles, and some carry Roush factory warranties (as opposed to Ford warranties).
