We unfortunately don't sell this coil balance system in sets, but we do sell the individual components. You ultimately only need to replace what's broken and can simply reuse the rest. The only exception to that is the spring itself; if you replace one, you really should replace them all. Otherwise the undamaged housing pieces are fine to reuse.

In your case, I would suggest the 15-087 housing pivot, 15-086 secondary housing, and Series 180 coil spring.

These parts are all designed to work on both the left or right hand side interchangeably.
