IMPORTANT NOTE: 7460-4007 Upper Ball Joint Installation Tool is required if your ball joint press kit is not equipped with a die with an ID minimum of 1.93” and a minimum depth of 0.86”. The EMF-K3134 joint can be pressed into place by a die resting on the cap, however it risks damaging the cap threads, leading to the possibility of not being able to rebuild or tighten the joint. This is your call if you want to purchase the tool or not - EMF is not responsible for damage to the cap that may occur during install without this tool.
** The upper install tool is to prevent the cap from being damaged when you press the upper joint into the knuckle. It just sits over top of the cap. It is not included with the ball joints, so if you would like it - please select it from the drop down menu.

Facts about the EMF Ball Joint:
- 2 Canadian and US Patents covering the design
- 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
- The entire unit is 100% Canadian Made by an Alberta Small Business. We have a strict Quality Assurance policy and each piece we make is numbered and logged with tolerances and measurements documented so if there is ever a problem we can look back on when it was manufactured and what the material specs were.
- EMF is the only Ball Joint with the removable race and pin (part of our patents). 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.
- EMF’s price point is set below the competitor pricing which is very enticing to the customer. We are not only a manufacturer and business, we are also the consumer so we wanted to have something affordable and high quality available.
- 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.
EMF Ball Joint Warranty
- Life-Time Warranty against Material and Manufacturers Defects. EMF will replace part of or the entire unit if it is determined to be an issue that falls under this category. The customer is encouraged to contact EMF directly to determine cause of fault and to receive warrantied products.
- Warranty does not cover breakage due to misuse of the product, improper installation or as a result of another component failure on the vehicle.
- EMF Ball Joints are meant to be rebuilt, which means the internal races and pin will wear over time under normal circumstances. The internal race and pin components are not covered by replacement Warranty, unless it is determined there is a manufacturer defect that caused premature wear. In order to maximize your product life, regular maintenance which includes tightening of the cap and greasing are required.
