Getting fed up...

I hate to resurrect an old thread, but Rock Auto stung me again. I don't know why I keep buying their garbage. But never again. The story is: I went to Autozone and they only sold Duralast brand front struts. I didn't want Duralast, based on past bad experiences, so I went on Rock Auto and bought KYB struts. When they box arrived at my house I noticed a sticker over a sticker on the box. So I peeled the top sticker off and saw that the label said Duralast...... Since time was marching on, with my car in pieces, I paid the mechanic to install the Duralast struts. After they were installed, the ride was so bad that i lost a hubcap and broke a headlight pounding over regular road bumps. So now I have to pay double to buy correct struts and installation. In addition to paying the ticket that the police gave me for the busted headlight.
So, was the box from Rockauto branded "KYB"? If so, they shipped the part you ordered. Duralast is just a brand, not a manufacturer like KYB, other than their rebuilt parts, so Duralast parts might be sourced from various manufacturers. Just like Sears old Kenmore brand, which could be an appliance made by GE, Maytag, or Westinghouse. Another example is ~3 battery manufacturers for ~100 brand names. One youtube recently showed an AC compressor (motorized) removed from a Tesla Model 3 with a FoMoCo label. Unlikely the Tesla factory would ship them thus, so perhaps an owner, mechanic, or source like Rockauto found the Ford part identical at a lower price. Kudos to Rockauto for such cleverness. I once found a new brake booster for my 1965 Chrysler on Rock for $80, when rebuilding mine cost >$350. Came in an old dusty box. Tom Taylor is good at finding stuff.

Don't know your vehicle, but take a ride in a Prius or Tesla Model 3 to experience "stiff ride". They probably design that to spec higher range, and ditto for the low-profile tires. Our Prius specs 42 psig tire pressure, as I recall. You want comfort, drive a 1960's full-size sedan with fat pimp-wall tires, but don't take turns too tight, and plan the path of the boat in advance.
