Rebuild Kits for Mercedes-Benz Engines If you'd rather rebuild your Mercedes engine on your own, we offer complete DIY rebuild kits for both diesel and gasoline Mercedes engines. These kits are available either as a mix of OEM and aftermarket parts, or exclusively Genuine Mercedes-Benz OEM parts. Before purchasing a rebuild kit you may want to check out our high-performance rebuilt diesel motors, and our remanufactured engines from a specialty Mercedes-Benz motor shop. We specialize in parts for classic Mercedes-Benz, and especially the diesels, however we can get both OEM and aftermarket parts for any Mercedes-Benz. If you don't see the rebuild kit for your engine below, please contact us to inquire about one for your vehicle.
