Koni Rebuilding options

[steveespo]

I have 2 front Koni Yellow Sport struts that have different issues and I was wondering where to send to have rebuilt. The first strut has a bad seal allowing the rod to sag down into the strut by gravity. The second has the adjuster seized so I can't adjust softer or firmer.
If anyone knows the contact info and typical cost for rebuild I'd appreciate it.
Thanks
Steve

Konis have a lifetime warranty. My rear shocks were rebuilt by Koni (North America) under warranty. You have to send them a request form with the shocks. Once they get them the request and shocks are reviewed. Once approved, they send out new ones or rebuild what you sent. The turn around on all this can be long, so if you want they offer an option to pre-pay for any non-authorized product (basically, you're paying for new gear and if they honor the warranty they refund it).

I sent one with the same blown seal issue and another with seeping out of the shaft seal. They warrantied both and I had them back after about a month (from my house to them and back.

Best,

I've had Jeff do many revalves. He's always had them back to within a week of receiving them.

Since were on the topic of koni shocks. I recently took mine out and when they are full stiff and I compress them all the way down by hand. They don't return to the fully extended position at the same time. One is a little faster than the other. Is this normal?

+1 on the recommendation of Jeff at ProParts.

I wouldn't sweat that as long as the difference isn't too extreme, say more than 10 seconds. My failed strut the rod drops all the way down in like 5-6 seconds after I fully extend it. No external leak on it which seems odd but I guess it can fail internally.

I timed my dampers on low and max settings before I ever put them on so I would have a diagnostic reference . So when mine were new: 10/11 sec rebound on low . On high 28/30 seconds .

Are you the original purchaser? Where did you get them from?

 

[steveespo]

I bought them new from Maximum Motorsports 11/19/12.

Hey Steve, if you remember, once you get your dampers rebuilt, would you time the return on low and max setting and post the results? Curious how far the variance is across production.

I realize this isn't exact science, but I think it would be a legit, rough indicator.

There is no oil leaking, and it stays fully extended. They just go from full compressed to fully extended at slightly different speeds on full stiff or soft. But I haven't had any issue with them on the car.
