We no longer offer a rebuild kit for the AD10 and AD12 rear shocks as production of these dampers ended over 15 years ago.

You can check with your local authorized service center to see if they still have seal kits available. Alternatively, you can use the part number's corresponding o-ring sizes to order through your local hardware store:

AD0106 - #011
AD0108 - #029
AD0110 - #123
AD0111 - #010
AD0125 - #004
AD0301 - #222 quad-ring
AD0302 - #027
