Is Moton also AST?

From what I remember however, the 4100 series had some pretty substantial reliability issues. They have had issues with the shocks leaking after one season, as well as failures in the design department.

Thats off the top of my head and some quick google searching. I know JRZ's will last 4-5 years with no rebuilds needed, as Sharif has a set on his personal GTR that have yet to leak or go soft since he put them on 4 years ago. He also has the older design that doesn't have bump stops or dust boots.
