The best recommendation I can give you since we don't carry the Gabriel actuators would be to check out the link I attached that will take you to a page that has all of the actuator shocks we carry. On the product pages for each there will be dimensions for each that you can compare to the shock you are trying to replace.

You'll want to know the hole center to center dimensions when retracted and extended. If you can get me the brand or style of actuator you help that might help me find what you are looking for as well.

@Patrick this is for a actuator shock? That's quite a bit of movement if so. Is there a brand or any other info you can see on the actuator?

@Ted Are you possibly looking for the Gabriel 61663 as that's a number I can find from Gabriel?
