Excellent sales department and products. Ordered new lb7 injectors, received a confirmation of the order, shipping updates, well packaged with clear core return instructions. Product was neatly packaged. Return and core payment was prompt and post installation follow up questions were professionally and quickly responded to ( I lost the balance rate sheet that shipped with the injectors and received a copy via email the next day. Top notch sales and support. I'll be using Lincoln for all my LB7's needs!
