Seeking 1915 Rear Radius Rod

Post by mortier » Tue Sep 02, 2025 1:17 pm

Anyone have a spare 1915 rear radius rod? The threads on one of the rods on my car are stripped.

Is it a cast iron end on the diff side you should probably just repair it it will be cheaper

Phil, yours is repairable if you want to go down that track. The worn section can be built up with weld, then ground/filed back into round. The good thread on the end gives you a lead-in to then use a die to make a new thread.
I have found 2 or 3 variations in the length of the round section of those rods, so finding a matching one, if that is important to you, may be a little frustrating.

I found a radius rod at Lang's, but I'm also attempting a repair of my old one. If that works, I'll post some photos.

My MIG repair worked well. Though not a concours winner, it's plenty strong.

Doesn't have to be strong. Filling the worn spot just tightens the potential movement if loose.
Did you deal with the corresponding wear in the DS tube?

I rebuilt the rear, so I think the driveshaft should be OK.
