New Billet and Cast Compressor Wheels for Diesel Turbocharger Rebuilds and Upgrades
The compressor wheel is the component that does the actual work of compressing air — spinning at speeds exceeding 100,000 RPM, it draws ambient air in and forces it into the engine at elevated pressure. We stock brand new compressor wheels in both billet (forged and machined) and cast configurations for Holset, Garrett and BorgWarner turbochargers. Applications cover Cummins, CAT, Detroit, Ford and other diesel platforms. Each wheel is matched by turbo model, inducer diameter, exducer diameter and blade count. Billet wheels are available as direct-fit stock replacements and as performance upgrades with larger inducer sizes for builds running added fuel. All wheels ship balanced and ready to install. US stock, no core charge.

The compressor wheel is the most damage-prone part in any turbocharger — dust ingestion, foreign objects and surge all attack the leading edges first. When the wheel is scored, chipped or eroded, the turbo loses efficiency and the rebuild needs a new wheel. We stock the specific wheel for the specific turbo, balanced and ready to press onto the shaft.
Billet compressor wheels are forged and CNC-machined from solid aluminum — lighter, stronger, and more precisely shaped than cast wheels. Cast wheels match the original OEM specification for stock rebuilds. We carry both so the shop can match the wheel to the application.
Compressor wheels are defined by inducer diameter (inlet), exducer diameter (outlet), blade count and trim. We match by the turbo model and the OEM wheel part number to ensure the replacement fits the bearing housing bore, the compressor housing scroll and the nut thread on the shaft.
Every compressor wheel ships individually balanced. When installed on the shaft and assembled into the CHRA, the complete rotating assembly should be VSR-balanced again before final assembly — but starting with a pre-balanced wheel significantly reduces the correction needed.
We stock stock-spec wheels for rebuilds to factory dimensions and larger-inducer billet wheels for performance builds running added fuel. A larger wheel flows more air but spools slower — match the wheel size to the engine's fueling level for the best result.
Coverage includes wheels for Holset HE300VG, HE400VG, HE351VE, HE351CW, HX35W and HX55 families, Garrett GT3782V and GTP38, BorgWarner S300V, S400SX4, B2UV and K03, and other common diesel turbo platforms.
One-year warranty on every compressor wheel. See the warranty page.

WHY CHOOSE US
We match by turbo model and wheel spec, hold common sizes on a US shelf, and support rebuild shops with fast turnaround. More about our company and quality process.
A cast wheel is poured into a mold — it matches the original OEM specification and is the correct choice for stock rebuilds. A billet wheel is machined from a solid forged aluminum blank — it is lighter, has tighter tolerances, and allows for blade geometry that casting cannot achieve. Billet wheels spool slightly faster than cast wheels at the same size due to lower rotational mass.
By turbo model and the original wheel's dimensions: inducer diameter (inlet side, in millimeters), exducer diameter (outlet side), and blade count. The turbo model narrows it to a family; the dimensions confirm the exact variant. The part number on the original wheel or the turbo's dataplate is the most reliable identifier.
Yes, if a larger wheel is available for your turbo's bearing housing and compressor cover. A larger inducer flows more air but requires more exhaust energy to spool — it works best on engines with added fueling. Contact us with your turbo model and current wheel size; we can confirm available upgrade options.
Yes. Every wheel ships individually balanced. For the final assembly, the complete rotating group (shaft, turbine wheel, compressor wheel) should be VSR-balanced as a unit before installation in the turbo.
All wheels are 100% brand new. No reconditioned or repaired wheels. Balanced and OEM-spec. One-year warranty.
Yes. Turbo rebuild shops order compressor wheels as regular stock. Consistent wholesale pricing from US inventory. See the wholesale page.
The compressor wheel is the heart of the turbo's cold side — it converts shaft rotation into compressed air. Understanding wheel specifications, materials, and sizing helps rebuild shops and builders select correctly.
| Spec | What it means |
|---|---|
| Inducer diameter | The inlet side of the wheel — determines how much air enters the compressor |
| Exducer diameter | The outlet side — determines the wheel's overall size and scroll fit |
| Trim | The ratio of inducer to exducer squared, expressed as a number — higher trim = more airflow capacity |
| Blade count | Number of full and splitter blades — affects flow characteristics and noise |
Cast wheels are the standard for stock-spec rebuilds. They match the original OEM dimensions and blade geometry, and they cost less than billet. Billet wheels make sense when the build demands more airflow (larger inducer), tighter tolerances, or reduced rotational mass for faster spool. On performance diesel builds running injector upgrades and tuning, a billet wheel is the standard choice. On stock rebuilds where the goal is restoring original function, a cast wheel is appropriate and cost-effective.
