Unhappy Bent the lower control arm...

First ride, took my Rush up to some freshly groomed trails this morning. Plenty of snow. The area I went had 4 feet of fresh snow this week and the trails great. Figures when I'm turning around I end up getting the side of my right ski hung up on a rock. Couldn't have been going more than 5mph (maybe 6 or 7mph). Stopped the sled immediately.

Gave the sled a very good look over and didn't see anything wrong. Went another mile and I could notice something wasn't right. The right ski was sitting just a little back further than the left. Gave it another more thorough look over and it appears the back of the lower control arm is bent downward (I'll post a pic). Possibly, but not noticeable the upper as well.

Maybe I was going faster than I thought...or maybe I'm used to trailing arms. But are these A arms designed to give so easily to protect the chassis?

Anything else I should look for that could be damaged?

Easy fix, just costly. Same thing happened with my '05 Fusion when I didn't see a snow covered ditch drain pipe. Ski slid inside pipe and it almost threw me over the hood. Knew it was bent right away and was able to ride it back home without a problem. Took me about a half hour and back to normal. As hard as I hit, I thought for sure the a-frame mounts in the bulk head got damaged. It's amazing how strong the chassis is on these sleds.

I'm more concerned about getting a lower arm in RED, :ohmy:

All the online microfiche only have part numbers for black...

i had the same thing happen to my 800 assault switch, same little bow in the bottom a arm. but i hit a pretty good sized rock snow covered in a swamp. i was pushing a trail. but no other damage. looked over everything pretty close. my buddy has a 08 800 doo xp gade and did the same thing on a smaller rock and totally mangled it. both a arms kinked, shock bent, tweaked and cracked two of the three peices that make up the lower bulk head. comparing our two collisions and we both were around the 10 mph when we hit the polaris took the hit allot better. Still isn't nice to hit anything but i was still able to put on 70 miles after and still riding as the do sits in pieces. i hear the arms are on back order for a week, polaris is/was out.

Thanks Johnny, I'll keep that in mind. I'm working with my dealer to get an OEM Indy Red part.

The trails were in Winona Forest (West of Tug Hill, east of Sandy Creek).

reading some of the mountain forums and those guys are having the same issues with bent A Arms. guess is they are designing them to take the crunch instead of your bulkhead??

If I want to replace this myself I had a couple questions.

Is there a trick to replace a lower and upper control arm? Do you need to compress the shock to remove it? Or is it fully decompressed when the sled is in the air?

Also, should any lock-tite be applied?

Thanks!

Sorry to hear about that jbspolaris. Here is the part number for the right hand side arm in red. 2204429-293

As for installation, lift the front of the sled up, remove bolt from shock there will be no pressure on shock when lifted. Remove swaybar mount. Remove bottom bolt into spindle, unbolt arm from chassis. You will also have to press out the ball end from the arm and put in your new arm. Put locktite in places it was on your old arm, locktite is not needed on locknuts. Hope this helps.
