I have read on this board to remove the little rubber bumpstops on the w-arm. Just wondering of any problems anyone had after they removed them? Im missing one, and was gonna remove the one in the sled rather then get a new one..I heard this almost stops the famous w-arm cracking..Just wondering what damage I would cause by removing these...would rather not rob peter to pay paul, if u know what i mean.as far as i know, rest of suspension is set stock....thanks...
 
REMOVE THEM they contrubuite to cracking the w arm ...but just cause u remove them dont mean you wont crack a w arm ....happens to all of them
 
If you bottom out hard enough without them, you will likely break more than the W-arm. With them installed they do transfer the energy of a hard bottom-out to a point on the w-arm that often breaks. Kindof a catch-22.
 
hmmm good thing i saw this thread, i didnt realize they were such a bad thing.. i mean i knew they contributed to w arm cracking but i didnt realize they were recommended to be tossed... ill be doing that later today!
 
We take them out all the time... it does help prevent w arm problems but if you dont add some spring tension to compensate for hard bottoming you may pound the shock cover and shock shaft rubber stopper apart.
 
two more questions

if i decide to put those bumpstops in, how the heck do they go in? i know the correct orientation, but how do you fit them in? and if i decide to leave them out, how do i know if i need to tighten those springs, and how do i tighten them? which spring needs to be tightend? the one closest to the front of sled or the one closest to rear?

They go in hard, the fin part goes in with a metal clip. Tighten the spring on the shock that attaches to that A-Arm only if you feel it bottom.
 
You should always use these. When you run without them, you overextend the front shock in a hard bottom, sometimes busting the lower mount and or the shock end if the mount twists. This can let the end of the busted shock stab track, spring can come off binding up inside and breaking other stuff. The bump stop is not so much there to stop the w arm, it is there to transfer the hard bottoming forces through the rails to the center fra shaft. Without it, you now have nothing to bottom this on but the w arm to the fra shaft all this transfered now through the bump stop on the shock.

best fix for the w arm is tight bushings, and slug the inside of the w arm tubes, then spotweld.
