HE400VG 5459711 Turbocharger for Cummins X15 Performance 525HP
The HE400VG 5459711 is the Holset VGT turbocharger for the Cummins X15 Performance Series, rated at 525 HP (CPL4343, CM2350). This is the higher-output variant of the X15 HE400VG family. The Performance Series turbo uses a larger compressor wheel compared to the Efficiency Series (5459710), which delivers more airflow at higher boost pressure to support the increased fueling. This listing is for the turbo assembly without the VGT electronic actuator. If your existing actuator tests good, reuse it. If you need both, see our HE400VG 5459711 with actuator listing. Built new with all new components, dynamically balanced, ships with gaskets. We supply shops, fleets, and distributors.

FAQ
The 5459711 is the Performance Series turbo (525 HP, CPL4343) with a larger compressor wheel for higher airflow. The 5459710 is the Efficiency Series (400-500 HP) with a smaller 63mm compressor wheel optimized for fuel economy. They share the same turbine housing and VGT mechanism - only the compressor side differs.
No. This is the turbo assembly only. Reuse your existing actuator if it tests good and run the ECM calibration after install. If you need both, see our 5459711 with actuator listing - it ships pre-calibrated for plug-and-play install.
The Cummins X15 Performance Series 14.8L, 525 HP, CPL4343, CM2350 platform, 2017-2021 model years. OEM numbers include 5459711, 5459711RX, 5358003, 5358483, 5358484, and 5351565.
Yes. The 5459711 bolts directly onto Efficiency Series engines with no hardware changes. The larger compressor wheel provides better airflow under heavy load. The ECM calibration stays the same. Some operators in heavy-haul or mountainous routes make this swap for improved breathing.
No. The 2021+ EPA21 X15 uses a redesigned HE400VG with different compressor wheel geometry. See our 5602145 EPA21 listing for that generation.
Brand new, 100% new components, dynamically balanced. Ships with gaskets. No core charge. One-year unlimited-mileage warranty.
Yes. US stock, volume pricing for shops, fleets, rebuilders, and distributors.
HE400VG 5459711: The X15 Performance Series VGT Turbo
Cummins offers two HE400VG configurations for the EPA17-era X15: the Efficiency Series (5459710, 400-500 HP) and this Performance Series (5459711, 525 HP). They look nearly identical from outside, but the internal compressor wheel is different. Getting the wrong one on your engine leads to either underperformance or calibration issues.
5459711 vs 5459710 - what is the actual difference?
The physical difference comes down to the compressor wheel. The Performance Series (5459711) uses a larger-profile compressor wheel that flows more air at higher pressure ratios. The Efficiency Series (5459710) uses a smaller 63mm round-edge inducer optimized for fuel economy at lower HP ratings. They share the same turbine housing, bearing housing, and VGT vane ring - only the compressor side differs.
| Spec | 5459710 (Efficiency) | 5459711 (Performance) |
|---|---|---|
| HP Rating | 400-500 HP | 525 HP |
| Compressor wheel | 63mm round-edge inducer | Larger profile |
| CPL | Various | CPL4343 |
| Best for | Fuel economy, line-haul | Power, heavy-haul |
The 5459711 can also be used as an upgrade on Efficiency Series engines to improve airflow at higher loads, though the ECM calibration remains the same. Some operators running 5459710-equipped trucks in heavy-haul or mountainous terrain swap to the 5459711 compressor for better breathing under sustained high load.
Identifying your turbo before ordering
The turbo nameplate on the compressor housing shows the part number. If you see 5459711, 5358003, 5358483, 5358484, or 5351565, you need this Performance Series turbo. If you see 5459710, 5358001, or 5358454, you need the Efficiency Series. If your engine is a 2021+ EPA21 X15, see the 5602145 listing instead - EPA21 uses a redesigned compressor wheel that is different from both EPA17 variants.
Failure modes specific to the Performance Series
The Performance Series turbo runs at higher boost and higher shaft speeds than the Efficiency variant. Bearing wear tends to show up slightly earlier at equivalent mileage, and the larger compressor wheel is more sensitive to air filter integrity. All other failure modes - vane sticking, actuator failure, oil starvation - are the same as the Efficiency Series. Refer to our 5459710 page for detailed VGT troubleshooting.
Installation notes
- This listing does not include the VGT actuator. Transfer your existing actuator if it tests good, then run the ECM VGT calibration procedure.
- Replace exhaust manifold and oil drain gaskets (included).
- Flush and inspect the oil feed line before connecting.
- Prime with clean oil and hand-spin the shaft before first start.
- Idle 3-5 minutes, verify VGT tracking through the ECM before loading.
