The Terareflex Rzeppa is a factory style replacement cv joint. The best thing about it is they have modified the "mouth" and made it so that your driveshaft can run at a steeper angle and not damage the boot. When ever you lift a jeep jk this is a common failure. This is a simple install and will take you about a hour from start to finish. And it will give your driveshaft cv joint a longer life.
