If you are replacing the front tires on your AFX with o-rings, I would take the chassis to an auto parts store. They will have hundreds of different sizes of o-rings to choose from. When you find the right one, that o-ring will have a size number. GET IT FROM THE PARTS GUY. Then you'll have it for next time. Good luck.

i used 108 orings. 1/4" ID, 7/16" OD, 3/32" Width

I wanted to try ones with slightly larger inside diameter next time, some times it fits too tight on certain rims.
109 for next time 5/16" ID, 1/2" OD, 3/32"

I ordered 100 of them and it took me 2 years to use them up :D


a guide for the Durometer

60 Shore A is softer than 70.

70 Shore A is the standard.

90 Shore A is very stiff.

they make a 55D white RVA oring and it is super soft.

You can also get any size o-ring you want at any hardware store that has plumbing supplies. Take a piece of test track, so you can eyeball which sizes would work. Be sure to write down the size for future reference. Once you determine the size, you can hit Ebay and buy a quantity of any size you need at a good price.

Do a seach for a thread called something like "AFX Replacement Fronts'. It was started by user Ligier Runner (may be misspelled). It has the size, part number and supplier.

I bought some from here:
http://www.paintballorings.com/

They have an excellent size chart:

You may be able to find some cheaper somewhere else but this place had the easiest site I found to navigate and the size chart helped me find exactly what I needed after measuring the front wheels. They shipped fast too...got them within a week.

bobwoodly is right. The #10 size is best for these. You can try smaller #9 or #8 and stretch around the wheel but in my experience these end up too small diameter and the guide pin shank drags the track and/or the pickup shoes bottom-out.

#10 o-rings on stock AFX front rims comes out to somewhere around .400 to .405 diameter.

And you can get these just about anywhere for super cheap. I think mcmaster,com has these for $2 and change for 100 pcs.
