Since the question of strength has came up, whats the best way to fix the problem. The pics show where I've seen 90% of the swingarms break.

You'd have to tube it in peices and halves to strengthen it there.

No, that's called rocks at GNCC. that's where they break.

I thought about just welding in a round tube all the way down the driveshaft area bottom to top. that way it closes up the hole where the swingarm bearings go.. thers room to get it down there. but it'd be a little harder to change the swingarm bearings.

Is there a way you could make a full length burly skid plate that even covers the pivot?

I think that is where, like E said, a full skid would help alot, but make it out of teflon or Delrin. Something that can take a beating, slide over stuff, and dampen the impact. It's either that, or make a non-cast swinger.

Why not just use the PBR one and but thin plastic on it that way it doesn't get stuck as easily on the rocks?

Cast parts don't flex. They crack. It's just the nature of cast parts. And most likely, they crack full out in one hit.

I have had one that showed a small crack first but most just break. Also I believe that a full skid plate is worest because you have to clamp it at the top were it is already weak.

That's what happened to mine. Going too fast, ran off the trail, flew through the air and the right rear tire came down behind a square 15" rock. Ripped the swingarm out from under the quad, all that kept it together was the brake cables. I ended up 20 feet ahead laying in the mud w/o a scratch! The rock never touched the swingarm; the force of the tire slamming into the rock tore the swingarm in half. It didn't do much for the axle, either.:eek:
