Hi guys,
I eventually found some x-rings (double edged o-rings) to suit Associated shocks. They are 1/8" ID, 1/4" OD and 1/16" CS so may fit other brands of shocks also. I have them in my sc10 and b4 and have had no leaking and they feel nice and smooth.
Unfortunately i had to buy alot to get any so i know have some for sale.
Price is £6.00 (paypal gift) or £6.50 (paypal goods) for 20 rings posted. May sound expensive but if you look at the price of alternatives such as Kyosho "grooved rings" (same thing) you can see thats a good deal. Such as these ones;

The ones i am selling are Nitrile buna 70d and do not expand as much as silicon rings when they come into contact with silicon shock oil. Can post pics if needed but they look they same as the kyoshos but black.
