Are these rebuildable?

[crooklyn]

Was wondering if these shocks are repairable?
If not what do you recommend?

I checked the shocks and couldn't find any names on them other then some numbers.

The #'s are:
503 1900 20 for the long back shock
the short middle shock on the track has no #'s
505 0707 53 on the the front shocks

I would say no, their not rebuildable

They are stock rebuildable / revalveable KYB's on a Doo.

as long as there is a place to charge nitrogen on the body of a shock, it is rebuildable.

75 each to change oil and orings. 150 each to revalve and rebuild.
