We study gauge extensions of the MSSM that contain non-decoupling D-terms,which contribute to the Higgs boson mass. These models naturally maintain gaugecoupling unification and raise the Higgs mass without fine-tuning. Unificationconstrains the structure of the gauge extensions, limiting the Higgs mass inthese models to roughly less than 150 GeV. The D-terms contribute to the Higgsmass only if the extended gauge symmetry is broken at energies of a few TeV,leading to new heavy gauge bosons in this mass range.Comment: 30+1 pages, 7 figure
