This is the Ultimate Racing Aluminum Steering Ball Link Protector. It is machined from T6-7075 aluminum and anodized in dark gray.

Designed to fit the ball link to prevent the rims from rubbing when turning the wheels and weakening the ball link.

Mounting: No glue is required. Place the protectors as far as possible inside the ball joints and thread the tie rod. As the tie rod is threaded, the plastic of the ball joint expands, locking the protector in place.
