Chevrolet OEM Spoilers

Chevrolet OEM Spoilers  are spoilers that are direct replacements for the spoilers that came on Chevrolet vehicles from the factory. Not all Chevy cars came with OEM spoilers so you can buy OEM style spoilers for your car  as an aftermarket item.

Here is a little history about Chevy and OEM Spoilers

The company was founded by Louis Chevrolet (Swiss-French) and William C. Durant (American). Louis was a race-car driver, and William Durant, founder of General Motors, had been forced out of GM in 1910. He wanted to use Chevrolet's designs to rebuild his own reputation as a force in the automobile industry. As head of Buick Motor Company, prior to founding GM, Durant had hired Louis  to drive Buicks in promotional races.

Chevy first used its "bowtie" logo in 1913. It is said to have been designed from wallpaper Durant once saw in a French hotel. More recent research by historian Ken Kaufmann presents a compelling case that the logo is based from a logo for "Coalettes".

Famous Chevy models include the large and luxurious Impala (1958) and the innovative air-cooled rear-engined Corvair. Chevy had a great influence on the American automobile market during the 1950s and 1960s. In 1957, Chevy made the first fuel injected engine. In 1963, one out of every ten cars sold in the United States was a Chevy.

The basic Chevy small-block V-8 design has remained in continuous production since its debut in 1955, longer than any other mass-produced engine in the world, although current versions share few if any parts interchangeable with the original. Descendants of the basic small-block OHV V-8 design platform in production today have been much modified with advances such as aluminum block and heads, electronic engine management and sequential port fuel injection, to name but a few. The small block Chevy V-8 is used in current production model (2008) Impala sedans, a variety of light and medium duty Chevy trucks, and the current generation Corvette sports car. Depending on the vehicle type, they are built in displacements from 4.8 to 7.0 litres with outputs ranging from 180 to 638 horsepower (476 kW) as installed at the factory. It will also be used as a performance option in the forthcoming (2009 model year) revival of the Chevy Camaro. The engine design has also been used over the years in GM products built and sold under the Pontiac. Oldsmobile, Buick, Opel (Germany) and Holden (Australia) nameplates. Recently, a 6-litre, 400 horsepower (300 kW) version of the small-block V-8 designed initially for the C-6 Corvette has been installed in a factory-built high performance version of the Cadillac CTS sedan known as the CTS-V.

OEM spoilers are factory or factory style spoilers, to match the original OEM spoilers that would have being a factory option.

Sports cars are most commonly seen with front and rear OEM spoilers. Even though these vehicles typically have a more rigid chassis and a stiffer suspension to aid in high speed maneuverability, a spoiler can still be beneficial. This is because many vehicles have a fairly steep downward angle going from the rear edge of the roof down to the trunk or tail of the car. At high speeds, air flowing across the roof tumbles over this edge, causing air flow separation. The flow of air becomes turbulent and a low-pressure zone is created, increasing drag and instability . Adding a rear spoiler makes the air "see" a longer, gentler slope from the roof to the spoiler, which helps to delay flow separation. This decreases drag, increases fuel economy, and helps keep the rear window clean.

One of the best remembered factory / OEM spoilers is the wing on the Road Runing Superbird and the Charger Daytona in 1970.

The main design goal of the spoilers in passenger vehicles is to reduce drag and increase fuel efficiency. While many often imitate wings and airfoils, these serve mostly decorative purposes. Passenger vehicles can be equipped with front and rear spoilers. Front spoilers, found beneath the bumper, are mainly used to direct air flow away from the tires to the underbody where the drag coefficient is less. Rear spoilers, which modify the transition in shape between the roof and the rear and the trunk and the rear, act to minimize the turbulence at the rear of the vehicle.

Also new vehicles today not only have rear spoilers, the also have front spoilers. The front spoilers, also known as an air dam helps to move the air over the front of the vehicle and not under the vehicle which create lift.
