Consistent quality part.

This is the correct heim joint for the trackbar on the Nissan Xterra solid axle swap kit from Calmini.Note that the trackbar uses two of these right-hand thread heims, not one right and one left like you'd expect.

These are top quality Messerschmitt joints (or ""Heim"" after the one licensed to copy the Messerschmitt product). I use these spherical rod ends for the drag link, tie-rod, and panhard rod on the steering and suspension of my 4x4. The spherical rod ends on the steering rods last a long time. The panhard rod puts a lot more force on the rod end, but these FK units still last longer than rubber bushings. After about 15K miles, the rod ends have a little play. Perhaps a larger one would last longer, but these fit the frame and axle attachments perfectly.

Ive had these joints on my aftermarket control arms on my 350z for a few months now. Still as quiet and function as well as the day I put them on. Good quality joints for a decent price.

GREAT product!! Excellent quality - very durable!
