Our Joints are 25 percent larger then OEM joints. You heard right! Our CV joints bearings and components are all 25 percent larger then OEM. The same goes for our shafts which are also a full 25 percent larger then oem (see pictures which show the difference) With the increase in strength you are not loosing any articulation angle our axles will work just fine with up to a 2 inch suspension lift. These are the last axles you will ever buy for your Rhino! Why don t other companies who advertise heavy-duty axles show you pictures of their product next to OEM axles? The answer is simple their axles aren t heavy duty at all! They are simply advertising
