These ball joints are manufactured by what we consider to be the best in the industry, Proforged. They’re serviceable with a grease nipple and will more than likely outlast the arm you choose to press them into.


The world’s finest ball joints from the name you trust – Proforged. Laboratory tested and proven in the real world, our ball joints feature improved design over the competition for increased longevity and durability, even in the most demanding conditions. Proforged Ball Joints generally utilize forged SAE4140 steel for the ball stud and forged SAE1045 for the housings, a combination that yields incredible strength and toughness. Proforged ball joints are available for nearly every year, make, and model vehicle found on the road today.


  • SAE1045 forged steeling housings
  • Ball studs forged from ultra-strong SAE4140 chromoly steel
  • Ring-retained, accordion-style boot
  • CNC-milled fit surfaces

Note – There is a difference between the MK2 / NB upper control arms and the NA arms, these ball joints won’t fit.

    Looks and feels like a real high quality US Made product. The finishing touch to my wishbone refresh.

    Lovely quality and reassuring to know it’s backed by a fantastic warranty, similar price to the few alternatives out there but far superior quality
