Got a Detroit Diesel Series 60 engine (like in many Freightliner trucks) that's running rough, has starting issues, or is throwing a check engine light related to timing? This MADAT sensor kit might be the fix. It includes both the camshaft position sensor (part #8929387) and the crankshaft position sensor (part #8929388) – two critical components that help your engine's computer know exactly where the pistons and valves are for perfect timing and fuel injection. Made from corrosion-resistant materials, they're built as direct replacements for the OEM parts. This specific set is compatible with Detroit Diesel Series 60 11.1L, 12.7L, and 14L engines found in many 1994-2007 Freightliner and other trucks (check the full fitment list to be sure for your specific vehicle). Easy to install if you're mechanically inclined, and getting both sensors together can save you time and money. Keep your big rig running smoothly with these reliable replacement sensors.
