While GT has used a paticularally unique suspension pivot design pretty much all rear suspensions are brand specific. Some brands do a better job at offering replacement parts for after market servicing. Some expect their bikes to have a limited lifespan and insted of having a business model with no long term support (meaning selling replacement parts for longer then the design is available on new bikes).


GT also has gone through various owners and distribution models in the past. I gave up trying to keep up with their stuff as it has become a bit player in the LBS market in general.


Good luck. Andy.
