Adjustable Ball Joints
Adjustable ball joints let you fine-tune front suspension geometry, which is useful when you're setting up a Mustang II style front end or dialling in bump steer. The range includes screw-in upper and lower ball joints, replacement ball joint studs, and related spindle and bump steer kit components.
Screw-in ball joints make it easier to adjust ride height or correct geometry changes without swapping the whole control arm, while a bump steer kit works alongside the ball joints to correct steering geometry when ride height is altered. Choose upper or lower depending on which joint you're replacing, and check that studs and spindles match your existing Mustang II style setup.
Frequently asked questions
What's the difference between upper and lower ball joints?
Upper ball joints connect the upper control arm to the spindle, lower ball joints connect the lower control arm; you need the one that matches the joint you're replacing.
Why would I need a bump steer kit as well as ball joints?
Lowering or raising a car changes the steering geometry, and a bump steer kit corrects that by relocating the tie rod end relative to the ball joint.
Are these parts specific to Mustang II style front ends?
Several items in this range, including the spindles and bump steer kit, are built for Mustang II style front suspension setups.
