Not that I can tell. I just installed 4 of them last week. 3 usa 1 China. Jeep drives fine.
I try to buy usa when I can. I was bummed when one shock was China. The China shock had better letter stampings on the body, a better paint finish, didn't over spray onto the rubber bushing, rancho sticker already installed (I throw the stickers out), and came with hardware. The usa shock was missing the nut for the top mount. Both were in sealed boxes. One had rubber dust boot installed other I had to install I forget which.
