[Crusty old shellback]

Picked up a few more parts today.
One nitrogen filling rig for shocks, tested to 200 PSI.

And so it begins.

Seems like the shaft of your rear shocks are exposed to gravel being down low like that.

Are the shafts pitted?

I wonder if a shield could be added?

 

[Crusty old shellback]

Shafts look good

But in screwed for now.

This is what Fox told me the charging set up was. What all the videos show. And what all the companies sell.
A rubber puck and a set screw with a hole in it.



This is what the shock actually has. A set screw with a rubber o ring. No hole. And it's bigger than the rubber puck and set screw.
So I can't even drill and tap it to fit



Called Fox, gave them the part number of the shock. Guy says oh, yea that shock is different and uses a different setup to charge it. I can see if we have the tool and I can sell it to you. Or you can send your shocks to us in Georgia and we can rebuild them.

Well screw Fox and their shocks and special recharging set up
Just called summit and they have the Bilstein 5100s in stock at the local warehouse. So driving over there to pick up a new set of shocks

Wow, was really hoping it would all work for you. I have the King 2.5 from Carli, I would like to rebuild them myself, when the time comes...

 

[G Mcpherson]

Like they Didn't know when you spoke with them.

Like they Didn't know when you spoke with them.

That's the part that pisses me off the most. Several email back and forth about schrader valves and the rubber pucks. Never mentioned to me that these shocks use something different.

I've rebuilt remote resi king shocks before. It's just a bunch of rubber o rings. Just take a good look at the shocks to see how you have to charge them. Could just be a schrader valve, which is the easiest way

The reservoirs have a cap on a schrader valve on my shocks... thanks

Out of curiosity I had to see how your Fox would be charged. Somebody overengineered that design. Here is the $400 tool

DAMN.

Fix called me back. I just told him to pack sand. Didn't even ask how much for the tool.

That looks more like a pain in the A$$ than the needle method

 

[Crusty old shellback]

One down
Three to go

Simple and easy then. Just ask king what the spec is for setting the floating piston in the resi.
Also need to try and get all the air out of the oil/ hose/shock.

Plenty of videos on YouTube on the process. And I'll answer any questions I can on the process. I rebuilt the same shocks on my K5. But at 12/18 inches of travel

 

[Dewey]

This is the fix not to have to buy the 400$ tool.

That could work, depending on the length of the valve that will stick out from the shock. Fronts are probably ok, rears id worry about.

But $20 a pop. WOW they are proud of them. But then again, Ive noticed everything there is double the price of most other places

 

[Dewey]

Ya a little much they stick out .950 and a cap may add .050. I used them on my front shocks I have not done the rear yet. I change service all 4 in the spring.

 

[Crusty old shellback]

Done



If anyone is interested in the Thuren tuned Fix shocks that need a rebuild, let me know.
I'll be posting them soon in the sale section.

 

[jebram]

How is the ride with the 5100's compared to the Fox?

 

[azrwilkinson]

I second this^^^^^
