BuyAutoParts 40-30314AN HX52

Updated May 13, 2026

Different Engines, Different Categories

These two products serve different engine families AND different product categories. The 40-30314AN is a complete Holset HX52 turbocharger for the Volvo D12 12-liter Class-8 engine. The HE351VE CHRA is a cartridge-only repair part for the Cummins ISB 6.7L pickup engine.

The BuyAutoParts unit ships as a self-contained assembly — center cartridge plus exhaust housing plus compressor housing — and replaces the failed factory unit in one mounting bolt-up. Direct-fit replacement for the original Holset HX52, Volvo OEM part number 3599996, 3599996-D or 20516147. The Holset HE351VE Cartridge CHRA is the center rotating group only — turbine wheel, shaft, compressor wheel, center bearing housing. Turbo Cartridge CHRA for Holset HE351VE. The buyer drops the cartridge into an existing usable Holset HE351VE exhaust + compressor housing assembly pulled off the failed unit.

The BuyAutoParts Complete-Unit Path

The 40-30314AN is the bolt-up path for Class-8 Volvo D12 buyers. One purchase order, one warranty term, one ISO/TS 16949 manufacturing standard covering the full assembly.

The warranty disclosure is explicit on the listing: Engineered for superior durability, backed by a one year, unlimited mileage warranty. For Class-8 fleet operators running a Volvo VNL or VNR with the D12 engine, the warranty term is the manufacturer-tier risk-management envelope against a $5,000-$15,000 all-in turbo failure event. The fitment language is the same blunt disclosure as the broader BuyAutoParts heavy-duty diesel catalog: 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 chassis.

The casting-stamp verification discipline applies the same way as on every BuyAutoParts heavy-duty listing: the only way to 100% guarantee fitment would be to look up any OEM part numbers off your original turbo. Photograph the failed turbo casting, match the visible Volvo OEM prefix (3599996, 3599996-D, or 20516147) against the cross-reference chain, order if the prefix lands on the published list.

The Holset CHRA Cartridge Path

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

A CHRA cartridge swap requires the rebuilder labor a complete-unit swap does not — cartridge alignment in the existing housings, end-float adjustment to the OE service spec, balance check on the rotating group, and oil-feed line replacement. For shops running a Cummins ISB rebuilder pipeline, this is routine work and the parts savings flow straight to the bottom line. For first-time installers landing on this listing thinking it is a complete turbo swap, the gap is real: the cartridge does not include exhaust or compressor housings, the wastegate actuator assembly, or any mounting hardware. None of that is on the listing page.

The listing has zero customer reviews on Amazon at extraction. Buyers depend on the source-knowledge ecosystem around Cummins ISB HE351VE rebuilds — Prosource Diesel's SPOOLOGIC line, KC Turbos' premium HE351VE complete units, MaXpeedingrods' aftermarket cartridges, and rebuilder shops with multi-year HE351VE field-experience reports — rather than first-party Amazon verified-purchase signal.

Counterfeit Risk on Chinese HE351VE Listings

The Holset HE351VE has a documented counterfeit pool. The Cummins ISB pickup chassis runs a high-volume install base and Chinese factory production of fake castings flows into the Amazon and eBay listing pool at fractional pricing.

A Turbo Tech UK employee in the r/Diesel community thread put it bluntly: we do have big issues with counterfeit items in Chinese markets, it won't have been burst tested.. The burst-test absence is the structural risk — a genuine Holset cartridge passes a destructive over-speed test as part of OE production QA; a counterfeit unit ships without that QA pass and can grenade under boost.

Authentication tells the same thread documents: 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 on the data plate: a missing red-text danger statement on the compressor housing data plate is a counterfeit signal. Buyers ordering Holset cartridges from any Amazon listing should treat these checks as mandatory.

The pricing tell is the most diagnostic of all: 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 Amazon listing for this CHRA is in the middle of the price band, not at the one-third counterfeit signal — but buyers still carry the authentication-photograph load.

If You're Coming From the Volvo D12 Side

If you're coming from a Class-8 Volvo VNL, VNR, or VHD with the D12 engine, the 40-30314AN is your part. The Holset HE351VE Cartridge CHRA does not fit your chassis — different engine family, different displacement, different turbo frame size.

The Volvo D12 production run covered 1995-2009 in North American Class-8 trucks before transitioning to the D13 platform. Buyers running a D12 chassis with an HX52 prefix on the casting stamp have the complete-unit path through the 40-30314AN, with a one-year unlimited-mileage warranty backstop and ISO/TS 16949 manufacturing positioning. For chassis that have since had the engine replaced with a Cummins ISX or X15, the cross-shop routes to the rebuilder-tier Class-8 segment instead — not to the Cummins ISB 6.7L pickup-chassis CHRA on this listing.

If You're in the Cummins ISB Ecosystem

If you're in the Cummins ISB 6.7L ecosystem — 2007.5-2018 Ram 2500/3500 pickup chassis 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 on your bench BEFORE ordering, inspect compressor housing and exhaust housing 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 reviews of the holset-he351ve-turbocharger-for-cummins-isb-5354495 complete unit or the asdpi-he351ve-he300vg cross-shop options, not through the CHRA cartridge on this listing. 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 turbocharger engineering background spanning both heavy-duty diesel and pickup-chassis applications, the Wikipedia Turbocharger encyclopedia entry documents the compressor-and-turbine architecture both products implement. For the Class-8 / industrial rebuilder context the BuyAutoParts unit sits within, the TSReman Turbo University service-part catalog publishes Holset HX52 cross-reference manifests on the Volvo D12 chain. For the Cummins ISB 6.7L cartridge rebuild context, the Rotomaster understanding turbochargers reference covers CHRA cartridge tolerances and rebuilder-tier specification practices.

Verdict: Choose by Chassis and Housings

Choose by chassis and existing housing condition. The 40-30314AN is the complete-unit path for Class-8 Volvo D12 buyers — warranty, ISO/TS 16949, ready to mount. The HE351VE Cartridge is the cartridge-only path for Cummins ISB 6.7L buyers with inspection-clean housings and a rebuilder-tier install discipline. These two are not direct competitors; they cover different engines AND different product categories.

Cross-Engine Decision Points

Are the 40-30314AN and HE351VE CHRA interchangeable?

No. The 40-30314AN is a complete HX52-frame turbocharger built for the Volvo D12 12-liter Class-8 truck engine — flange standards, exhaust-housing geometry, and compressor map all sized to the D12 exhaust gas volume. The HE351VE Cartridge CHRA is a bare cartridge (rotating group + center bearing housing) sized for the Cummins ISB 6.7L pickup-chassis engine, intended to drop into an existing usable Holset HE351VE housing assembly. Different engine families, different product categories, no interchange.

When does a CHRA cartridge make more sense than a complete unit?

When the failed turbo's exhaust + compressor housings are inspection-clean and the failure was confined to the cartridge — bearing failure, shaft play, compressor-wheel damage from foreign-object ingestion that didn't score the housings. Re-using a clean OE housing assembly and dropping in a fresh CHRA cuts the parts spend roughly in half versus a complete-unit swap. The trade-off is the rebuilder labor (cartridge alignment, balance, end-float adjustment) and the loss of a complete-unit warranty backstop covering both housings AND cartridge.

Why are there counterfeit Holset HE351VE turbos to worry about?

Holset is a Cummins-owned Class-8 OE turbo brand. The HE351VE serves the Cummins ISB 6.7L pickup chassis (2007.5-2018 Ram 2500/3500) and a deep aftermarket-rebuilder install base. Counterfeit Holset castings flow out of unofficial Chinese factories at fractional pricing. The r/Diesel community thread atoms in our mining substrate document specific authentication tells — casting numbers, machining finish, internal-inspection green marks, data-plate red-text danger statement — that buyers should photograph and verify before fitting.

Does the BuyAutoParts 40-30314AN warranty cover the same as the HE351VE listing?

The 40-30314AN listing publishes an explicit one-year unlimited-mileage warranty. The Holset HE351VE Cartridge CHRA listing has zero customer reviews on Amazon at extraction and does not publish a warranty term beyond Amazon's standard return window. For Class-8 fleet operators where downtime cost dwarfs parts spend, the explicit warranty term on the BuyAutoParts side is a documented manufacturer-tier backstop. The CHRA-side buyer carries the warranty uncertainty load alongside the cartridge-vs-complete sourcing decision.

Which side fits Dodge Ram 2500/3500 pickups with the 6.7L Cummins?

The Holset HE351VE Cartridge CHRA side. The listing names Cummins ISB part numbers 5354495, 6411490, and 5354552 — the OE chain for the 2007.5-2018 Ram 2500/3500 with the 6.7L Cummins ISB engine and the variable-geometry Holset HE351VE turbo. The BuyAutoParts 40-30314AN does not fit any Dodge Ram pickup — it serves the Class-8 over-the-road Volvo D12 engine on the VNL / VNR / VHD chassis. Different engines, different chassis envelopes.
