OE 1638800029 — Gas Spring Bonnet for Mercedes-Benz

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the gas spring bonnet should be inspected, and reference 1638800029 replaced if it measures outside specification.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest suspension, steering & brake reference and narrow by build year. Send photos and we will cross-check the number for you.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 1638800029 with other suspension, steering & brake references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a gas spring bonnet the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.
