Griffin has been in full production of diesel wheels since 1966. Using our proven design, we produce diesel wheels cast to such close tolerances that they are better balanced than most steel wheels. Such balance contributes to maximum traction, smooth ride, and longer wheel life.

• All Griffin diesel wheels have witness grooves so the recontouring operation will better produce matched tapes throughout the locomotive.

• The parabolic sweeping fillets that connect both sides of the diesel wheel plate to the rim result in lower stresses, giving you a safer wheel with more resistance to failure.
