EMF is the only Ball Joint with the removable race and pin (EMF Patented Design). Competitor products have a removable pin that can be rebuilt, however the inside of the housing will wear as the pin wears resulting in the inevitable replacement of the entire unit in the future, as the pin will no longer possess a tight fit. By having the internal race and pin set on the EMF ball joint, the race will act as the wear point instead of the housing body creating a long lasting unit.
Each EMF Ball Joint unit is made from 4140 HTSR material and then sent to a metal treating facility to be Nitride Coated. Liquid Salt Bath Nitriding is a second heat treating process on the material resulting in up to a 30% strength increase as well as a beautiful black oxide corrosion resistant coating that also resists galling and does not reduce the tolerances of the pieces.
Rebuildable so you will never have to purchase an entire unit again, you simply replace the inner race and pin and off you go. You can do this right on the truck without removing the housing from the knuckle.
Serviceable so if you ever start to feel movement in the joint, you simply back out the set screw on the side of the cap and tighten the cap then replace the set screw. This can be done right on the truck without having to remove anything from the knuckle.
Greaseable so you can just pump a couple squirts of grease into it around every oil change and go.
