Genuine Spicer light vehicle axle products are manufactured to the same high standards as original equipment (OE) parts because they are OE parts. That means when an automotive axle part is replaced with a genuine Spicer part, you are getting the same performance and reliability you have come to expect. And because Dana is constantly revolutionizing the technology behind its Dana axles and Spicer products, the replacement car axle or component you purchase today may even exceed the standards set for the original equipment part that you are replacing.
