These Pedal Extenders are easy to install and can be adjusted to add two, three or four inches to the pedals of most vehicles. They improve driving comfort and safety for shorter drivers because they allow the driver to move back from the steering wheel and to rest the heel on the floor. This is something most drivers take for granted but for those who are used to driving with an extended toe, this a great relief. The price includes an extender for the gas and brake pedals. We recommend a booster cushion for most drivers since the booster cushion helps give the driver a better view of the road immediately ahead and a much better view behind the vehicle for backing up. They won't eliminate the need for an airbag on/off switch in many cases, but will improve driver comfort. These extenders can easily be re-installed on another vehicle when the car is traded in. (Note: If you need a clutch pedal it costs $65 extra but there is no additional shippping cost). These extenders can be returned for any reason within 30 days of receipt. Returns must be fully assembled with all parts included.
