Full 2001 GMC Sierra 2500HD Review
What's New for 2001
Both light- and heavy-duty 2500s sport new torsion bar front suspensions. Light-duty models now offer optional traction control and standard child safety-seat tethers. Heavy-duty Sierras are completely redesigned for 2001 offering two new engines and transmissions, bigger interiors and numerous other improvements aimed at buyers looking for a "professional grade" truck from GM.
