Need some new lock nuts for my radius and trailing arms and I'd like to try to source them from McMaster or someplace cheaper than AB. I'm having a rough time stomaching $6/nut for the radius/trailing arm end nuts.

I'm looking for the actual nut sizes for:
Radius arm, at the axle (x4)
Radius arm, at the frame (x2)
Trailing arm, at the axle (x2)
Trailing arm, at the frame (x2)

The nuts at the chassis are all M20 locking nuts. The others are M14 diameter, 80mm length maybe? I'll double-check that once I get back to the office (might be m16, 100mm)

If you didnt remove them yet you might want to wait and see if you need the bolts too. I remember needing to cut off my radius arm to axle bolts for whatever reason.

Yeah I checked Rovahfarm actually. That particular nut though, looks like it is quite a bit shorter than the one currently on the arms. Which is why I was looking elsewhere.
Already had the bolts out, when replacing the arms. The nuts don't hold quite as well the second time around.

Radius arm to axle bolts are M16 diameter, 100mm length, I have used 2.0 thread pitch in the past but factory is a little more coarse. Just make sure whatever nuts you order match of course. Not sure on the thread pitch for the M20 nuts. The M14x80 bolt is for the panhard rod.

x2. And if the blue doesn't do a good enough job for you, step up to red. Any vehicle wheeled ought to be loaded with thread locker.
