Which Shocks for SS Springs?

So, I've noticed that the Left-Side is Higher?
I definitely have the 002 on the right side.
I have a KYB Gas-A-Just KG5511 on the Left...
Is that Long enough?
I have an Unknown Brand Air-Shock on the Right.
Maybe the Air-Shock is Too short now with the New Springs...
Should I put another KG5511 on the Right-Side or
is there a Preferred Longer Shock for Use with the SS Spring?

Thanx Fabo!
