Precision Remanufacturing
This Turbo Kings remanufactured turbocharger is engineered specifically for the Detroit Diesel DD13 engine platform and is equipped with the OEM-style pneumatic wastegate actuator. Each unit undergoes a complete teardown, followed by high-temperature alkaline treatment and ultrasonic cleaning to remove carbon buildup, soot, oil residue, and corrosion from all internal and external surfaces. Compressor covers, turbine housings, and bearing housings are then media-finished and inspected using digital metrology to ensure every dimension meets or exceeds OEM geometry.
The CHRA is rebuilt using brand-new journal bearings, thrust assemblies, piston rings, seals, and fasteners. Rotating components are matched as balanced sets, and all lubrication channels are restored to full flow capacity to ensure proper oil film support at high RPM. Every surface that interacts with lubrication or exhaust gas is reconditioned to provide OEM-grade sealing, thermal stability, and turbine efficiency. The result is a reman DD13 turbocharger that behaves exactly as a new unit would under commercial duty cycles.
Seal Integrity and Boost Control Stability
Turbo Kings places extra emphasis on sealing surfaces and wastegate calibration—two of the most common failure points on aging DD13 turbos. The wastegate actuator is replaced or fully reconditioned and calibrated to Detroit-spec cracking pressure, ensuring proper modulation of boost under varying load conditions. The actuator rod, lever, and bypass components are tested for stroke accuracy, ensuring the turbo responds correctly to ECM demand without over-boosting or under-boosting.
Sealing interfaces between the CHRA and turbine/compressor housings are resurfaced to eliminate leakage paths. Bearing pockets and thrust surfaces are restored to precise oil-clearance windows, which is critical for preventing oil consumption and ensuring stable shaft rotation at high boost. This ensures your DD13 turbocharger returns to service with the correct boost profile, consistent spool characteristics, and reliable performance under long-distance or mixed-duty operation.
What Makes Turbo Kings Different
Every Turbo Kings reman turbo is engineered for long-term commercial reliability, not quick cosmetic rebuilding. Our process includes:
High-speed VSR balancing at progressive RPM stages
Calibration of wastegate actuators to exact cracking pressure
New bearings, seals, and thrust hardware in every CHRA
CHRA assembly in a controlled, filtered environment
Pressure testing of compressor and turbine housings
Dimensional restoration of all mating surfaces
Final functional testing of bypass and boost-control components
Serialized documentation for traceability
This ensures each unit meets OEM expectations for boost, durability, and emissions stability.
Why Fleets and Owner-Operators Trust Turbo Kings
Commercial engines rely on consistent boost behavior, efficient turbine flow, and proper wastegate control. A Turbo Kings reman DD13 wastegated turbo restores:
OEM spool response
Accurate boost control under load
Proper exhaust backpressure balance
Improved fuel efficiency
Reduced fault codes related to boost deviation
Long-term reliability through clean lubrication circuits and balanced rotating assemblies
Our remanufactured units are built to withstand port work, regional haul, construction fleets, and mixed-duty applications where uptime is critical.
