Damper Top Thread Size

PostPost by: Gorpon73 » Mon Oct 03, 2022 3:46 pm

Hello,

Wondering if anyone would possibly know offhand the size of the thread at the top of the damper. The part that secures onto the end of the damper shaft above the lotocone, not the thread that secures the top of the damper body in the housing.

Thx, DJS

Pretty sure it’s 11/16 UNF.

You need to state Gorpon what dampers you have fitted, as as you can see, threads vary between damper manufacturers. I have various castleated nuts and they are not all interchangeable.

It does, but I tried to put what I thought was a 5/8 UNF nut on it, but it didn't fit! That's why I went quiet

Sorry for the confusion. I was expecting them to be the same as I've had three different sets which all used the same nuts, although the nuts aren't all the same design....

I'm now working with the top adjustable Koni sports. Curious for an tool idea.

I do not have top adjustable nuts :lol: so cannot help with the thread size, sorry. Are those the yellow Konis that use nylocks to secure, and if they are, I would think that the thread is metric?

My top nuts are 11/16” UNF, which I consider a very odd size. I expect Leslie is correct, as I believe Koni are a European manufacturer. Thread systems can be treacherous as some are very similar but not quite the same. To be more certain what you have you need the diameter and the pitch. Thread pitch gauges are available and look like little saw blades with the pitch or threads per inch (TPI) written on them.

Hope this helps,
