Camburg 1.50in. 4130 Uniball Cup

If you're building your own upper or lower control arms, spindles, or links for your off-road rig, these uniball cups from Camburg are a solid choice. They're designed to give you maximum misalignment and strength, which is crucial when you're pushing your suspension to its limits. Camburg machines these cups in-house from US 4130 chromoly steel, so you know you're getting well-built components that aren't made from cheap, imported mild steel.

What sets these apart is that Camburg also machines the outside diameter to remove material scale and finish, which helps ensure a cleaner, stronger weld when you're fabricating your suspension parts. They're ready for either MIG or TIG welding, and you can even heat-treat them after fabrication for added durability. This 1.50-inch version is a standard size, perfect for many custom lower control arm and link applications where you need a strong mounting point.

Remember, these cups are sold individually and do not include the snap ring or bearing, so you'll need to source those separately for your build.
