Browse our inventory of used OEM Infiniti parts sourced from US-based salvage facilities. Every component is a genuine factory-original part inspected for condition and listed with full vehicle compatibility details. Infiniti is Nissan's luxury division — every Infiniti model shares its platform with a Nissan equivalent, which means the much larger Nissan donor pool is fully accessible for Infiniti structural and drivetrain components at significantly better availability and pricing. Free shipping on all US orders. VIN fitment confirmed before dispatch.
New OEM Infiniti parts carry a luxury brand premium over equivalent Nissan components — despite sharing identical engineering, the same factory, and in many cases the same OEM part number. An Infiniti QX56 rear subframe and a Nissan Armada rear subframe from the same production year are the same unit. Understanding these cross-references is the most valuable knowledge an Infiniti owner can have for used parts sourcing — and our listings reflect it, with Nissan cross-references noted in product titles throughout this collection.

Nissan Pathfinder (R52) / Nissan Quest (partial) |
QX60 and Pathfinder R52 share their unibody platform — front subframe, ABS pump, and CVT transmission cross-reference within the same generation. Source CVT from sub-60,000-mile donors only |

QX56 & QX80 — Our Strongest Infiniti Inventory
The Infiniti QX56 and its successor QX80 represent the strongest section of our Infiniti collection. The QX56 rear subframe (2008–2011, shared with Nissan Armada) is one of our page-1 ranked listings — a testament to the demand for this component and the depth of our inventory in this category. If you own a QX56 or QX80 and need a structural or drivetrain component, contact us with your VIN and we can cross-check the Nissan Armada inventory simultaneously for the fastest match.
VQ Engine Family — Infiniti's Shared Powertrain
Infiniti's VQ engine family is shared extensively with Nissan. The VQ35DE powers G35, FX35, M35, and EX35 — and cross-references with Nissan 350Z, Murano, Altima V6, Maxima, Pathfinder, Frontier V6, and Quest. The VQ37VHR powers G37, Q50, Q60, and M37 — cross-referencing with Nissan 370Z. Engine components from either Infiniti or Nissan donors are directly compatible within the same VQ variant.
