Used on my 91 240sx, non-HICAS steering system. argued that this was not the case. Despite this, the fit is good and the bellows are not overtightened/compressed from lock to lock. Installation was easy, a small amount of lube on the small tip of the shoe made it easy to move. The quality seems ok, the material is quite flexible but holds its shape well. Again, I didn't have a stock comparison, but I think they should be good for a few years, which is certainly good enough for a car that's around 30 years old. The method of attaching the large end of the trunk was difficult to use when crawling. under the car so I had to replace the mechanics cable there, but your mileage may differ
