Control Arm Fabrication
Control arm fabrication parts for racers building or repairing their own suspension arms rather than buying complete assemblies. This covers ball joint sleeves and rings used where a ball joint screws into a fabricated control arm, letting you set up the correct thread size and fit for your chassis.
Screw-in sleeves come in different sizes to match the ball joint being used, so check what size ball joint your arm is built around before ordering. These are the kind of small but important parts that determine whether a fabricated arm goes together properly and holds up under load.
Frequently asked questions
What's the difference between the small and large screw-in sleeves?
They're sized to match different ball joints, so you need to pick the sleeve that corresponds to the ball joint thread size you're using in your fabricated control arm.
Do I need a ball joint sleeve for every control arm build?
Yes, if you're fabricating a control arm that uses a screw-in ball joint, you need a sleeve welded or fitted into the arm to accept that joint.
