350Z and G35 Coupe Factory Propeller Shafts: Model, Construction and Transmission Identification

No checked formal successor was exposed for complete 350Z shafts 37000-CD000/37000-CD100 or G35 Coupe shafts 37000-AM600/37000-AM610; the official/dealer paths currently describe the 350Z identities as discontinued and the Infiniti path as backordered, so no replacement number is invented. Explicit hardware relationships are 37120-AL600 -> 37120-AL60A, 37171-AL600 -> 37171-AL60A, 37512-4P010 -> 37512-4P011, 37120-CG200 or 37120-CG205 -> 37120-CG20A, and 37171-7S000 or 37171-0P000 -> 37171-7S00A. These fastener/support changes do not supersede the complete shaft and do not prove 350Z/G35, Coupe/Roadster, manual/automatic, RWD/AWD, one-piece/two-piece or OEM/aftermarket interchange.

Begin with both 17-character VINs and build dates. Verify 350Z versus G35 Coupe, Coupe versus Roadster, factory RWD, automatic versus six-speed manual, readable installed or donor service identity, transmission output/sleeve interface, differential companion-flange pilot and four-bolt pattern, actual spider-to-spider dimensions, tube diameter/construction, balance marks and every included part. The 350Z and G35 Coupe can share transmission or differential families without sharing propeller shafts: the 350Z uses one-piece CFRP 37000-CD000/CD100, while the longer G35 Coupe uses two sections, a center bearing and AM610/AM600 identities. The Infiniti catalog exposes some same-number RWD Sedan option text, but this page does not authorize Sedan donors because live listings commonly confuse Sedan and Coupe; require Coupe-specific donor evidence or a current VIN lookup. Do not apply aftermarket pages' 2008 G35 Coupe wording to the US 2003-2007 V35 Coupe scope. Factory shaft lengths are identification checkpoints measured spider-to-spider, not shipping-box dimensions or permission to order by overall tape measurement alone. A bare 350Z shaft does not automatically include rear flange bolts/nuts, transmission seal, fluid, exhaust hardware or protectors. A G35 sale may omit the center bearing, upper/lower brackets, center-joint hardware, rear flange hardware, shields or balance hardware unless itemized. On a used 350Z CFRP shaft, reject a dropped part and inspect for dents, cracks, chipping/bending, bond/seal peeling, lost yoke-to-tube clearance, abrasion and missing balance marks; the factory joints are non-disassemblable. On a used G35 two-piece assembly, additionally inspect both tubes, center bearing noise/play and rubber deterioration, bracket distortion, center-flange alignment marks, staked/lock hardware, splines, seal surface and all joints. Factory manuals require zero journal axial play and year-specific runout limits, so use the exact service manual and qualified driveline measurement rather than a seller's spins free claim. Preserve matching/balance orientation and replace non-reusable hardware as the exact procedure directs. After installation, check clearances, leaks and vibration safely; a high-speed driveline is not a place for improvised welding, straightening or unverified balancing.

Transmission- and model-specific one-piece aluminum or carbon-fiber replacements exist, but they are not generic 350Z/G35 shafts. Checked paths include Z1's configurable 350Z one-piece aluminum shaft and Driveshaft Shop G35 Coupe manual aluminum 610101/INSH1, automatic aluminum 610102/INSH4-A and manual carbon-fiber 610103/INSH1-C. Require the exact recipient model/body/transmission, manufacturer part number, published flange/spline interfaces, tube diameter, measured length, included adapters and hardware, balance method/speed, power/speed limitations, clearance requirements, serviceable-joint statement, lead time, warranty and return terms. A one-piece G35 conversion removes the factory center-bearing arrangement and changes construction/NVH; it is a modification, not an OEM supersession. Inspect transmission, differential and subframe mounts and full-rotation clearance because a larger tube or drivetrain movement can create contact. Do not assume a seller's 2003-2008 G35 Coupe label proves a US 2008 G35 Coupe application, and do not treat universal/custom shafts, G35 Sedan, G35x/AWD, G37/370Z or swap products as factory-equivalent choices.

for US/LHD factory-RWD 2003-2008 350Z Coupe, 2004-2008 350Z Roadster and 2003-2007 G35 Coupe only. The 350Z uses one-piece CFRP manual 37000-CD000 or automatic 37000-CD100; the longer G35 Coupe uses a two-piece center-bearing manual 37000-AM610 or automatic 37000-AM600. Verify both VINs, transmission, readable identity, spider-to-spider dimensions, spline/flange interfaces, construction, balance/condition and exact contents. Do not infer 350Z/G35, Coupe/Roadster, automatic/manual, Sedan/Coupe or RWD/AWD interchange. Reject dropped or damaged shafts and use the exact factory inspection/installation procedure.
