Just before Christmas we replaced both front struts on my L322. We ordered Delphi units from the supplier. There were no manufacturer markings on the boxes nor anywhere on the struts. The bags are marked Made in Mexico and the top plates are marked made in Spain.

The boxes are marked with the Delphi part no., the LR part no., and Made in UK but no manufacturer name:

Might be worth asking Dan at Duckworths on this?

Certainly when i replaced my Delphis with Delphis a few years ago, they were in Delphi boxes and labelled Delphi (although made in Mexico) .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember

The ones I bought last year from island 4x4 where exactly like yours. Sold as Delhi but no manufacturer named on them. Thought it was a bit odd but needed to get them fitted so didn't query it. They have been fine so far.

Interested in what you find out.
