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).

Perhaps best known of these Roush-modified vehicles is the Ford Mustang, which in 2016 is available in the "RS" (3.7 liter V6, with body kit, stripes, wheels, and interior modifications only), "Stage 1" (standard 5.0 liter V8, with body kit, stripes, wheels, and interior modifications only), "Stage 2" (standard 5.0 liter V8, with body kit, stripes, wheels, suspension, and interior modifications only), and "Stage 3" (body kit, stripes, wheels, suspension, interior, and exhaust modifications, with the addition of an Eaton-supplied 2.3 liter TVS-2300 "roots-style" supercharger). The addition of the supercharger to the Ford-supplied 5.0 liter engine on the Stage 3 version results in a horsepower output of 670. All Roush factory cars are 50 state street legal. All packages are available in both coupe and convertible models, in either manual or automatic transmission (automatics are special order only).

The company has served occasionally as a part-time sponsor for Roush's Xfinity Series teams.
