Turbo Compressor Wheels

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.

Billet or Cast — Matched to Your Turbo and Your Build Goals

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 and Cast Options for Every Build Goal

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.

Matched by Turbo Model and Wheel Dimensions

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.

Dynamically Balanced Before Shipping

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.

Stock Replacement and Performance Sizes

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.

The Most Damage-Prone Part in the Turbo

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.

Rebuild and Performance Shop Supply

One-year warranty on every compressor wheel. See the warranty page.

FAQ

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.

Turbo Compressor Wheel Guide

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.

Key Compressor Wheel Specifications

SpecWhat it means
Inducer diameterThe inlet side of the wheel — determines how much air enters the compressor
Exducer diameterThe outlet side — determines the wheel's overall size and scroll fit
TrimThe ratio of inducer to exducer squared, expressed as a number — higher trim = more airflow capacity
Blade countNumber of full and splitter blades — affects flow characteristics and noise

Billet vs Cast: When Each Makes Sense

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.

Compressor Wheel Damage Patterns

  • Leading edge erosion — Fine dust and particles wear the blade tips over time, reducing flow efficiency. This is the most common form of compressor wheel damage on trucks operating in dusty environments.
  • Foreign object damage (FOD) — Larger debris (bolt fragments, gasket pieces, filter debris) strikes the blades and causes chips, dents or fractures. Any visible FOD requires wheel replacement — a damaged blade creates imbalance at high RPM.
  • Surge damage — Repeated surge events stress the blade roots and can cause fatigue cracking. Inspect the blade-to-hub junction for hairline cracks during rebuilds.
