Detroit Diesel Engines & Parts

Kustom Truck Parts supplies factory remanufactured Detroit Diesel engines and premium supporting components built for reliable performance in semi-truck repowers, engine swaps, and ongoing maintenance. Detroit Series 60 platforms are trusted for exceptional longevity, torque, and serviceability, but successful integrations—especially into chassis that began with a different engine—require precise, conversion-ready parts for wiring, mounting, cooling, and electronic compatibility.

Our lineup features Factory reman Series 60 engines and upfit parts like serpentine upfit kits, fan hubs, mounting brackets, intake manifolds and more. These direct-fit solutions ensure seamless integration—reducing fitment issues, preventing electrical/mechanical problems, and minimizing downtime.
