Alignment, Shocks, And Struts

The suspension system consists of shocks and struts. Their main purpose is to keep your vehicle’s tires firmly connected to the road. When shocks and struts get worn your car looses that firm connection to the road and its stopping ability is diminished. We make sure all your Steering and Suspension components are working the way they were designed to ensuring you are driving a safe vehicle.

Tire Services

The tires on your car are very important for the function of the vehicle. You can have a well functioning engine and transmission system, but without tires, you are not going anywhere or stopping safely. Because of the importance that tires have for the use of the vehicle, it is important that they are properly maintained and cared for. Flex Auto Center provides our customers with high quality tire replacement and service in Washington and St. George, UT.
