This is not an aftermarket part, it is OEM. Additionally, there is no core charge and this is not a reman (RX).These units are OEM "take-offs", they are brand new and unused but do not come in Cummins retail packaging. We buy complete units from Cummins and then dismantle them so that we can sell the pieces individually. Due to this, there may be paint marks or minor cosmetic blemishes, but we assure you they are brand new and genuine.

This has been fully inspected. Performance will not be affected by the possible blemishes on these products. See the attached photos.
