ATL Diesel has been the camshaft expert, leading the industry since 1973. We spent decades remanufacturing camshafts for Dealers across the country but now we also sell directly to owner-operators, OE dealers, and large fleets alike. All of our Reman camshafts are completely remanufactured, NOT just used camshafts that have been cleaned or polished like many other companies sell. Every single lobe goes through the machining process to ensure that it meets OEM specifications for hardness, duration, and lift. We have 99.99% of all camshaft part numbers available, if you are unsure and need us to verify for you, just give us a call and our dedicated sales team will be happy to assist you. In order to receive a credit for your return, parts must. Have NEVER been used (kits must still be in unopened package). Be in original condition (no dirt nor grease on the parts). Gaskets, gasket sets, seals, seal kits and/or manuals of any type.
