no alleyway those are just the strut bags.....air cylinders are and actual aluminum cylinder that fills with air.....much more durable.....adam i have also had many experiences with bag and cylinder setup and have installed many sets on my freinds cars....and yes im sure uve done them hondas and let me tell u our mcpherson suspension is much more com plicated beacuse of the fact that the strut twists in its pocket as we turn out wheels.....talk about wearin out O-rings on the cylinders......ive never installed the AIM industries bag struts but have seen them on a contour and they SUCK!!!! they dont slam the car but about 3 inches......the owner said they leaked all over the top mount etc etc.......and basically are POSs
