Wheel Chock for GMC Sierra: Mountain Roads
This wheel chock is the version most often ordered for mountain roads 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: documentation that arrived after the container shipped, or warranty claims traced back to a single lot. Both come from a specification that was never written down.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
Ordering checklist
- Confirm the model year, market version and mounting points.
- State the duty cycle; mountain roads 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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.
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.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
