Look around, most of the shocks in the country are made by the same couple of countries, I know when we had a Wal Mart auto center a couple of years ago, I was able to buy shocks from them for less than any of the auto parts store and they were made by the same company that makes Gabriels, NAPA, O' Reilly, Car Quest, they were all the same shocks painted a different color with the store brand name on them. it is amazing how few companies actually make shocks and struts. The last set of struts I purchased for the Subaru, we some weird name off ebay with free shipping, got all for struts with free delivery in 3 days, opened the box and there was a paper in there from the company that makes KYB struts. I have not run a set of Highjackers for a couple of decades now. When I figure out they were mostly being made by the same companies to the same specifications, I just go with the lower priced house brands.
Living where I do, my shocks get a real work out, believe me!
