Optimally your piston should be a simple two force member, that is, only experiencing direction extension or compression loads. Many times this is accomplished via ball joint fittings, or having enough play in its pivot that it doesn't take any load.
Keep check on load paths through the module and it should be easy enough to be sure the piston isn't taking any bending loads.
