Tricycle Cargo Box for GMC Sierra: Construction Sites
This tricycle cargo box is the version most often ordered for construction sites on the GMC Sierra. It is supplied to a written specification covering material, dimensions, finish and packing, and that specification stays on file — so a repeat order is a reorder, not a new negotiation.
What usually goes wrong is ordinary: packing that arrived crushed at the port, or a specification nobody had written down. Both come from a specification that was never written down.

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.
Ordering checklist
- Confirm the model year, market version and mounting points.
- State the duty cycle; construction sites is not the same specification as occasional use.
- Approve a sample built from bulk material.
- Fix packing and marking before the first container.
- Inspect before balance payment.
Questions buyers ask
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the DOT-compliant build instead of a fresh interpretation.
