I am working on a vengeance chopper softail that brakes it’s shock bolts every couple of thousand miles. It brakes one or the other front bolts. I added a safety plate ( I can’t believe it came without one) so I won’t pogo on a shock anymore when it brakes but I can’t figure out why it breaks bolts. The bolts are good quality. The shocks are fine (I even took one apart to see if it was long enough when the swing arm bottomed out). The swing arm stoppers are fine ,the shocks are aligned.
Any ideas?loop-single-reply.phpJuly 3, 2014 at 11:56 pm #3178Stop riding off curbs…no fat chicks on the back?? (Sorry I couldn’t resist making a wise-a$$ comment its a Holiday weekend.) But seriously, the Daytec frames all came with color-matched shock plates that bolt into the welded-in mounting block in front of the shocks. That’s there to keep from tearing the shock apart if you high-side. I assume there are no trauma marks on the frame so the shock is resisting stretching more than the bolt is resisting breaking. It sounds like you’ve inspected all the culprits… Replace the shocks.

loop-single-reply.phpJuly 4, 2014 at 10:47 am #3181July 6, 2014 at 12:23 am #3182I’ve gone through the shock bolt breakage, the rubber eyelets the shock bolts go through wear out & get egg shaped causing play while extended or contracted. The side shear stress on the mount bolts makes them break, the bolts are #8 tinsel strength a very strong but brittle. Also the shock length is important to undo shear bolt pressure. Progressive sells new eyelet rubber grommets, they have to be pressed in, I changed my 03 Warrior at 5k and currently have 26k with no problems. You can put adjustable lowering rod ends on the shocks to insure you have the propper shock length to the Daytec frame travel. Good luck bro-Vengeance riders. ๐
