Chassis systemsUse vehicle and physical product evidence together; the visual does not prove fitment.

Decision workflow

Turn a broad Land Cruiser request into traceable inquiry lines.

1. Map the driveline

Record transmission, transfer case, center/front/rear differential, ratio, locking system, shafts and actuators.

2. Name the suspension system

Standard dampers, AHC hydraulic units, adaptive dampers and KDSS cylinders are different product families.

3. State axle and side

Use front/rear and vehicle-left/right, then add mounts, splines, sensor provision and measured interfaces.

4. Do not infer from appearance

Use system labels, diagnostic context, removed-unit marks and dimensions before approval.

Evidence hierarchy

Use the strongest evidence without forcing an OE number.

Vehicle evidence

Chassis/VIN context, series, build date, market, engine, transmission and suspension/4WD system define the application.

Part evidence

Use a reliable OE/reference when available; otherwise use labels, interfaces, position, dimensions and old-part photos.

Commercial evidence

Quantity, grade, sample status, packing, destination and approved alternatives define the quotation.

Auto parts inquiry

Send the vehicle and part evidence.

Include brand, full model, year, engine or EV drivetrain, OE/material code, quantity, destination and packing request. You can attach a list or old-part photos.
