I thought you guys might be interested in seeing this picture. The shocks were about 2.5 years old and used with a 375/300 GC setup. For the last 2 years, they only saw daily driving duties. I noticed that the car had started bottoming out in the rear recently. This is what I saw when I took off the wheel!

The shaft broke at a groove where the shaft diameter increases.

OW. Must be those Virginia roads - I took my hyperco/agx'd' B13 up there recently to play with my kid in Richmond; I've been down here (Atlanta) for six years, but I will NEVER complain about the condition of city roads down here again. Richmond must not have filled a pothole since I left. So much for tax cuts: no $ for infrastructure.

wow... hope you got home ok

Wow, that's the second car I've heard of doing that.

That sucks, good to see you managed to get it home.

That is NUTS man. I have never seen an AGX strut do that and I have prolly installed 4 sets on friend's cars. Crazy.

Perhaps the rear bushings are shot and it's causing the strut to move around enough to snap the shaft? Or maybe you're torqueing the top shaft nut a little too tight? Perhaps it's a little of both? Just throwing out ideas....:dunno:

I probably drove it about 600 miles in that condition!

That's pretty f#cked up right there

I don't think so. I replaced the suspension with a new hyperco/agx setup. The mounts were in good condition. The top shaft nut does not apply load to that part of the shaft.

Well at the very least KYB should replace under warranty.

:biggthump

I filled out the contact form on the KYB website and asked if they wanted to inspect the failed components. I never heard back from them. Coilovers void the KYB warranty so I just ordered new ones (my 3rd set). KYB did replace my first set under warranty. However, Stranos never reimbursed me for my replacement costs (AVOID STRANOS!). Looking at the failure surfaces, it appears that it was a fatigue failure which initiated at a defect at the groove. The crack slowly grew about 1/3 of the way across the shaft until the shaft fractured completely. I may get a friend to put it on the SEM to take a closer look.

OOOH SNAP!!! That sucks bro' :eek2: :eek2: :squint: :(

L

OOOH SNAP!!!

Literally.....;)

wow... that is just not good at all.. you seriously could have rolled your car EASY to avoid something.

Stop buying AGX, get Konis

Seriously, the roads/streets in Richmond proper are as bad (or worse) than those in Minneapols/St. Paul. Apparently, none of the road crews around here know what a pavement transition is. :(

AGXs are fine. every company has defects. even koni.

yikes... for the record, what were your dampening settings at?
