Anyone else brake the swingarm on their trike?

Looks like very poor (South of the Border) welding. Nearly missed the joint completely or the welder didn't intend on hitting the joint in the First Place.

On the IRS (LLS Lehman) the swingarm acts as a dead-man. There is stress as the picture shows but I believe it is defective construction.

I have to agree.



Question?

Is this only on the IRS suspension models?

I have seen no evidence of cracks on my champion straight axle.

I have to wonder if the failures were a part of a certain serial number run, Date of manufacture etc?

I bought my kit in the spring of 2013.

The only ones I have seen (2) are on the LLS models, not the straight axle models.

As far as I know, this was an IRS model issue only and was addressed by Champion a long time ago. I'm not sure of the exact time frame, but they totally changed the way the swing arm is reinforced. It is boxed on all sides now. I will post pictures shortly of one I am building now to show you all what the new part looks like.

Swing arm up-graded

Papa Zook You are correct on the new improved swingarms. The new replacement is also boxed on all 4 sides with what looks to be a little thicker metal ? The old style that cracked only had the 3 sided sleeve that appeared to be of a lighter gauge material? Welds also look better on the later style ? Time will tell and I'll add this "check swingarm" to other weekly checks (tire pressure, fluid levels, belt, ect.) Thanks for input!
