BuyAutoParts 40-30796AN HX35

Updated May 13, 2026

Different Cummins Engines, Different Frames

These products serve different Cummins engines on different chassis envelopes. The 40-30796AN is a complete fixed-geometry HX35 turbocharger for the 5.9L Cummins 6BT in industrial applications. The HE351VE CHRA is a variable-geometry cartridge-only part for the 6.7L Cummins ISB pickup chassis.

The chassis distinction is explicit on the BuyAutoParts listing: This is for the Cummins 6BT in an industrial application - Does NOT fit any Dodge Ram pickups!. Industrial Cummins 6BT applications run fixed-mount engine beds with stationary manifolds — generator sets, marine mains, irrigation pumps, stationary fleet equipment. The HE351VE Cartridge CHRA targets the opposite chassis envelope — the 2007.5-2012 Dodge Ram 2500 / 3500 pickup with the 6.7L Cummins ISB and the variable-geometry Holset HE351VE turbo platform. The listing names the Cummins ISB part-number chain (5354495, 6411490, 5354552) that the cartridge drops into.

The Industrial Cummins 6BT Path

The 40-30796AN is the complete-unit bolt-up path for Cummins 6BT industrial buyers. One purchase order, one ISO/TS 16949 manufacturing standard covering the full assembly.

The manufacturing-standard disclosure: 100% BRAND NEW replacement turbo, premium ISO/TS 16949 quality. The category framing is direct: This is an exact-fit replacement turbocharger meant to replace the existing turbocharger on your vehicle. — direct OE-chain replacement, not a performance upgrade and not a kit for non-turbocharged 6BT chassis.

The Holset HX35 OE cross-reference chain on this unit covers six casting-stamp prefixes: Replaces Holset HX35 3537132 3537133 3537134 3537135 3537136 3537137. A buyer photographing the failed turbo casting should see one of these six prefixes — a match confirms industrial-6BT fitment. Dodge Ram pickup buyers with the 5.9L 12-valve or 24-valve Cummins should see a DIFFERENT Holset HX35 variant on the casting stamp and route to the pickup-chassis path through our Fleece Performance HX35 Cheetah coverage or the rebuilder-tier alternatives, NOT to this industrial-only listing.

The HE351VE Pickup Cartridge Path

The HE351VE Cartridge CHRA is the cartridge-only path for Cummins ISB 6.7L pickup-chassis buyers whose existing housings are inspection-clean. Lower parts spend, higher rebuild-discipline load.

The fitment is named directly on the listing: Turbo Cartridge CHRA for Holset HE351VE — sized for the 2007.5-2012 Ram 2500/3500 chassis with the 6.7L Cummins ISB engine. Variable-geometry vane geometry, integrated wastegate actuator interface, and a cartridge-bearing assembly compatible with the Cummins ECM calibration on those chassis years. The 2013-2018 Ram chassis runs the HE300VG (smaller-flow VGT) and is not in this cartridge's envelope.

A CHRA swap requires the rebuilder labor a complete-unit swap does not — cartridge alignment in the existing housings, end-float adjustment, balance check, and oil-feed line replacement. For shops running a Cummins 6.7L rebuilder pipeline, this is routine work. For first-time installers landing on this listing thinking it is a complete turbo swap, the gap is real: the cartridge ships without housings, without the wastegate actuator assembly, and without mounting hardware.

Counterfeit Protocol on Chinese HE351VE

The HE351VE has a documented counterfeit pool. The Cummins ISB 6.7L install base is high-volume and Chinese factory production of fake castings flows into Amazon and eBay listing pools at fractional pricing.

The structural risk is the missing destructive QA pass: we do have big issues with counterfeit items in Chinese markets, it won't have been burst tested.. A genuine Holset cartridge passes a destructive over-speed burst test as part of OE production QA; a counterfeit unit ships without that QA pass and can grenade under boost. The industrial 6BT side has its own QA-bypass risk pool, but the HE351VE pickup-chassis pool is the more documented one in the r/Diesel community substrate.

The authentication checklist from the same community thread: the numbers in the casting are good quality, the machining from what I can see looks good and well finished and the green mark suggests it's been through an internal inspection. Photograph the casting numbers, inspect machining cleanliness, look for the internal-inspection green mark before installing. A second authentication tell is on the compressor housing data plate — a missing red-text danger statement signals a counterfeit.

The pricing tell is the most diagnostic: if you're buying a "new" one for 1/3 what a Cummins regional distributor charges, and they don't want a core returned, good chance its a counterfeit.. Cummins does not sell direct to retail in China; any vendor proclaiming "directly from the factory" at one-third distributor pricing is sourcing from an unofficial production line. The 40-30796AN sits in a different category here — BuyAutoParts is a US-based supplier with ISO/TS 16949 manufacturing positioning, not a direct-China-factory listing.

If You're Coming From the Industrial Side

If you're coming from a Cummins 6BT industrial application — generator set, marine main, stationary fleet equipment — the 40-30796AN is your part. The HE351VE Cartridge CHRA does not fit your chassis. Different engine displacement (5.9L vs 6.7L), different turbo frame (HX35 fixed-geometry vs HE351VE variable-geometry), different product category (complete unit vs cartridge).

The industrial 6BT install base spans irrigation pump engines, fleet generator sets, marine mains on smaller commercial vessels, and stationary equipment running the Cummins 6BT as a power-take-off source. The casting-stamp discipline applies: photograph the failed turbo, match a 3537132-3537137 prefix on the Holset HX35 chain, order if the prefix lands on the published list. Confirm the chassis is industrial (not a Ram pickup, not a Class-8 truck) before fitting — the listing's no-Dodge-Ram exclusion is a hard fitment fence, not a marketing technicality.

If You're in the 6.7L Pickup Ecosystem

If you're in the Cummins ISB 6.7L pickup ecosystem — 2007.5-2012 Ram 2500/3500 with the variable-geometry Holset HE351VE turbo — the cartridge CHRA path is on the table when your existing housings are still serviceable. Photograph the failed turbo BEFORE ordering, inspect exhaust and compressor housings for scoring or galling, and route to the cartridge path only when both housings pass inspection.

When the housings are damaged or marginal, the complete-turbo path is the correct route — through our Cluster B coverage of the complete HE351VE unit, the asdpi-he351ve-he300vg cross-shop for 2008-2010 chassis-year coverage, or the rebuilder-tier specialty alternatives (Fleece Performance, BD Diesel, KC Turbos). The bare-cartridge path is a parts-spend optimization for shops with rebuilder discipline; first-time installers carry too much uncertainty load against the parts savings to make it the right route.

For the underlying Cummins engineering background spanning industrial 6BT and pickup-chassis ISB, the Wikipedia Turbocharger encyclopedia entry documents the fixed-geometry vs variable-geometry architecture both products implement. For the industrial-rebuilder context the 40-30796AN sits within, the TSReman Turbo University service-part catalog publishes Holset HX35 cross-reference manifests on the Cummins 6BT chain. For the variable-geometry HE351VE cartridge-rebuild context, the Rotomaster understanding turbochargers reference covers VGT cartridge tolerances and rebuilder-tier specification practices.

Verdict: Choose by Engine and Chassis

Choose by Cummins engine and chassis envelope. The 40-30796AN is the complete-unit path for Cummins 6BT 5.9L industrial buyers — fixed-geometry HX35, ISO/TS 16949, no Dodge Ram fitment. The HE351VE Cartridge is the cartridge-only path for Cummins ISB 6.7L pickup-chassis buyers with inspection-clean housings and rebuilder-tier install discipline. These two are not direct competitors; they cover different engines, different chassis, and different product categories.

Cummins Cross-Application Decision Points

Does the BuyAutoParts 40-30796AN fit Dodge Ram 2500 pickups?

No. The 40-30796AN listing explicitly excludes Dodge Ram pickup applications — it serves the Cummins 6BT 5.9L in industrial generator, marine main, and stationary fleet applications only. For Cummins 6.7L pickup-chassis buyers on the variable-geometry HE351VE platform, the cartridge CHRA on this comparison page is the cartridge-only path; the complete-unit path runs through the rebuilder-tier Holset HE351VE complete-turbo coverage or the BD Diesel / Fleece Performance specialty alternatives.

What is the displacement difference between these two applications?

The 40-30796AN serves a 5.9-liter Cummins 6BT industrial engine. The HE351VE Cartridge serves a 6.7-liter Cummins ISB pickup engine. The 6BT was the prior-generation Cummins inline-6 (1989-2007 production), and the ISB 6.7L is its successor on the Ram pickup platform (2007.5-2018 with the HE351VE turbo, then HE300VG on 2013-2018 chassis). Different exhaust gas volume, different turbo frame sizing, no interchange.

Why is the HX35 frame different from the HE351VE frame?

The Holset HX35 is a fixed-geometry turbocharger sized for the 5.9L Cummins 6BT exhaust gas volume. The Holset HE351VE is a variable-geometry (VGT) turbocharger sized for the 6.7L Cummins ISB. The HX35 has no actuator-modulated vane geometry; the HE351VE has the variable-geometry vane assembly that modulates boost across the RPM range and integrates with the post-2007.5 Cummins ECM. Different frame size, different boost-control architecture, different OE chains.

Cartridge CHRA viable when the 6.7L pickup housing is damaged?

No. The HE351VE Cartridge CHRA is a rotating-group repair part intended to drop into existing usable Holset HE351VE exhaust + compressor housings pulled off the failed unit. When the failure damaged either housing — scoring, galling, casting cracks, wastegate-actuator mount damage — the complete-turbo path is the correct route. Cluster B coverage of the complete HE351VE unit and the asdpi-he351ve-he300vg cross-shop options addresses that scenario; the cartridge path on this listing assumes both housings pass inspection.

How does the warranty disclosure differ between these two listings?

BuyAutoParts 40-30796AN does not publish an explicit warranty term in the verified atom set, though it carries the standard ISO/TS 16949 manufacturing positioning and no-core-deposit return policy. The Holset HE351VE Cartridge listing has zero customer reviews on Amazon and does not publish a warranty term beyond Amazon's standard return window. Both listings carry warranty uncertainty load relative to the sibling 40-30314AN Volvo D12 unit which publishes an explicit one-year unlimited-mileage warranty.

For the broader Cummins-family context spanning 6BT industrial, ISB 6.7L pickup, ISX15, and X15 chassis, route to the cross-engine turbocharger roundup, or size aftermarket spend against the dealer quote with the Turbo Replacement Cost Estimator.
