You talking shock spring spacers?
If so.... It's gives a false lift by only increasing spring load. Makes the ride stiffer and the sxs sit taller. It does not add any angle outside factory specs as the shock max extension point stays the same. Some of us have done it to the front and rear shocks on the 700.
They can be cheaply made at home too.
I have a walkthrough somewhere for the 700, same concept for the 500.
