Wow Darren. I didn't think it was possible for the Kings to fail. I see the seal is separated from the housing. Is that due to too much pressure build-up? We used to have to bleed the air from the front forks on our motorcycles after each race or the seals would leak just like yours. Is that an air fitting on the remote reservoir? Are you supposed to bleed those regularly?

I think the shaft just got mucked up with all the road crud we had this year, lots of metling and freezing. Then it pulled the dust seal out. After that the crud got into the oils seals I guess. Should have maybe tried to keep the shafts clean a bit? I always have preffered boots but they told me no need for them.....
I do pound on this thing pretty hard, even with 1,500 lb of fire wood in the back I was ditch banging a couple of weeks ago
Thanks for the MX ref, I think I will get my buddy in Calgary to re build it, wonder what he is up to these days........

Well......
One leaking shock was kinda funny and I considered it a fluke.
But now I have 2 leaking and it is kinda making me mad.
King shocks have no warranty which I can kinda see for their typical application.....but I would have expected them to last a year for a daily driver application.
But, Carli has said they will pay for the rebuild kits if the shafts are not pitted (which they are not, the shafts are stainless steel and smooth as a whistle). Good on them I supose. This part surprises me..... NADP (North American Diesel Performance) has said they will cover the cost of getting the shocks re built (whick will be the majority of the cost, expensive oil and expensive labour). So really good on them. As far as I am concerned, that is going above and beyond the great service they have always given me. If you need anything for your truck in the Edmonton area, tuner, titan tank, amp steps and almost anything else NADP will treat you right!
Also foundout, Bilstein 5100's have a lifetime warranty, I did not know that! Pretty cool as lots of guys here have them.
I will have to purchase a cheap set of shock to run while the kings are sent back for repair.
That's where we are at, it will be a while before I can get the truck in and a while to get the shock fixed. I will let you all know how it truns out.
OH YA, I am sending all 4 back, yet to be determined who will be paying for the 2 that are NOT leaking but pretty sure it will be me. With 2 leaking I want all 4 looked at so there are no more issues.....
Thanks

I have a set of gently used Rancho OEM Fx4 shocks from my F-350. Only 9K miles and they still work . I'll sell them for $1.55 each plus shipping

My family/friends have been running King 4.0/4.5's bypass shocks for 10+ years on their desert cars (Cali dunes) and nobody in our group ever had a King go bad so I wouldn't expect it to be a regular occurrance, especially with how much we abused them (whooped out sections at 70mph, jumps, etc). My dads latest car is running Fox shocks/bypasses and he's been satisfied with them but it took us much longer to get them tuned correctly than the Kings ever did.
I kept my (junk) stock shocks in the event I had to send the 9000's back, but since yours is lifted, it may be worth it to have an extra (decent) set on hand in case you have anymore issues with the Kings. I hope you don't, but ya never know...

Save some steak and potatoes for me, I will be prety hungry by the time I get there.
