  If supersymmetric partners of the known particles have masses at the
multi-TeV scale, they will not be directly discovered at planned future
colliders and decouple from most observables. However, such superpartners also
induce non-decoupling effects that break the supersymmetric equivalence of
gauge boson couplings $g_i$ and gaugino couplings $h_i$ through supersymmetric
analogues of the oblique corrections. Working within well-motivated theoretical
frameworks, we find that multi-TeV scale supersymmetric particles produce
deviations at the 1-10% level in the ratios $h_i/g_i$. Such effects allow one
to bound the scale of kinematically inaccessible superpartners through
precision measurements of processes involving the accessible superparticles.
Alternatively, if all superpartners are found, significant deviations imply the
existence of highly split exotic supermultiplets.
