Cummins QSB 3.3L Timing Gear 4 Cylinder Diesel Engine.

Diesel technicians agree that aftermarket parts, especially made overseas, don’t have the same standards or durability as original OEM parts. As dealer inventories of OEM parts diminish, technicians are faced with the unfortunate choice of resorting to cheaply-sourced aftermarket parts or rebuilds from worn-out cores. OSMI Parts has great news as we have received new, original hard-to-find parts directly from Cummins! Why risk using a rebuild, used or cheaply-sourced overseas aftermarket part when you can have the new original Cummins part in hand and ready to install?
