Ouch!!!

Today ride got cut short by some major carnage. Came up over a hump quickly, shock bottomed out.....snap. I recently had the shocks reworked and they changed the springs and are not heavy enough (thanks Mr Obvious). Rode RB for three days with just me and the wife and I knew the springs were a bit soft but no real issues. Today we had four people which definitely overloaded the springs. When the shock bottomed out it almost knocked the top of the shock off and snapped the trailing arm right at the shock mount. It snapped a 2" .25 wall chrome moly arm like a twig. Took the wheel off, strapped up pieces and drove it out on three wheels   Managed to get it out and loaded up without any more damage. Got back and just parked the trailer and did not mess with starting to fix it. I'll drag it in the garage tomorrow and asses the damage but so far the obvious is: Trailing arm, shock, inner CV, fender, rear body panel, tail light, all trashed.






Guess I'll start ordering more parts Tuesday  

Wow that's the first time seeing that happen.

Wow! Thats a hell of a break! My Special Carriers trailing arms are holding up well. Going to put on the rest of their parts this week. Sorry about your luck.

Dang!

The trailing arm is not the problem. When the shocks were rebuilt the they used too soft springs for the weight. They also changed the shock bumpers which are also too soft. When the shock bottoms out and the suspension is loaded something has got to give. That's the problem with 4130, even though it's much stronger it tends to break rather than bend. $hit happens when you play tough with your toys.

Sorry about your trouble Joe. It might be all of that blue.

And I was pissed because I pinched a brand new tire....you win!!!!

No worries, all is good. It was probably because I put a red gas can on her Jagged X blue machine    Still need to order a "blue" kerosine can to replace the red one

   I win.... I think   

I know what the problems was... I wasn't there so the black cloud picked another jagged x... LOL Sorry to here about the bad luck. I think the black cloud jumps from jagged x to jagged x. I finally got mine all put back together this weekend. I ended up putting new super dave's bushings in the front as well as a gusset kit from to strengthen all of my arm tabs. Good luck on fixing everything.

Update: Found a set of shocks on the big forum (about the same as Polaris wants for one)and ordered all the other parts from polarispartsmonster.com. I'll talk to ORB tomorrow and he should replace the trailing arm. Ordered new axle (Rhino) and a new CV to repair this axle (got HD spares now). Will talk to smoothride tomorrow about the springs. Now I need to find the motivation to move it from the trailer to the garage    

Hey Joe, what is the dia. of those trailing arms. Don't know if it's just the pic but they look small?

No

When a shock bottoms out hard:

Upon closer inspection last night, I don't think the shock bottomed out. I never felt it bottom out nor any hard hits. I think the shock bent as a result of the trialing arm breaking. You can see at the top of the shock where the top screws on how it's been tweaked. I think the shock was bent back, the resovior hit the frame and bent inward toward the spring.

Talked with ORB and Justin is sending new redesigned arms out today.

Ouch !! That's Krazy it ripped a 1/4" thick DOM tube like that, spin jarring.

Remember when some of us on here were suggesting Zbroz trailing arms  
I agree that it had nothing to do with the spring rate but what was your spring rate? Just wondering.

That hurts. At least you were able to get it out of the woods. Do the other aftermarket manufacturers use 4130 tubing? Or are they mild steel DOM that will bend instead of breaking?

Smoothride did them, the fronts are 175#, not sure what the rears are. Same setup Marty has on his machine.

Well I hope I don't have that problem.... I went with your suggestion and bought the ORB trailing arms.    No worries its all good.

Check the bottom of the trailing arm and see if the angle iron that's welded to the bottom goes all the way back to the lower tube, if so it's fine.

No way the shock broke that trailing arm. No way!!!! I know ORB is a good dude but Smoothride knows shocks.

That arm broke then shit happened. I have to agree with what 8 ball said about trailing arms....

Nope, was not the shock no doubt. Tim is great guy, got a new set of rear shocks headed his way. The arm broke right behind the angle iron welded to the bottom of the arm. There is a ~3" gap between the re-enforcement angle and the lower tube. Created a weak point and metal fatigue caused it to break. Could not see this happening on a two seater but the extra weight of the four took it's toll.
