The factory struts are Bilstein, although they don't make a quick strut for it. Avoid the Detroit Axle ones on Amazon. Their other components are rock solid, but their shocks and struts didn't seem to be made for these vehicles. Rears started leaking 6 months in and I'm going to be replacing the fronts. I used the Duralast ones from AutoZone in the rear and have had no issue. I'll be doing the same for the fronts.
i put monroe quick struts in my front and they are doing just fine.
i wanted to go for ranchos, but this was my first time doing this and didn't want to start compressing springs. (couldnt find any rancho front strut assemblies, why not?!) someone should just assemble a few and put em up for sale
AC Delco makes a ready strut for the trailblazer, it’s on Amazon for $190 apiece,I just put in the original skinny front Bilstein struts and rear Bilstein shocks that came on my trailblazer, it had the premium smooth ride ZW7 package from the factory, found them on eBay, had to rent the spring compressor from advanced auto to put the struts in, hardest part was getting the rusted nut off the rod of the old struts.
