to have z55 or z95 (09-14 Esky) active struts, here's the breakaway diagram for the assembly order. On my truck there is no dust boot or spring insulator visible. This leads me to believe that an installer decided it was easier to just
get er done since he forgot or didn't know to order them.
I've been poking around looking at Dorman & Arnott's loaded front z55/z95 assemblies that retail for 5-$6h each. There's a big red flag on both items. Dorman and Arnott state that they're compatible for both z55/z95 (Denali / LTZ & Esky) They're not the same. One is filled with hydraulic oil and the other is filled with
magnetorheological fluid. Both are valved differently, and both have a different control module.
It appears as though Arnott & Dorman are
selling their z55 struts as z95. They state that they're cross compatible strut has
magnetorheological based fluid. This just can't be. The z55 hydraulic filled struts would ride like **** if that were the case. I saw that Arnott is offering money for z55 cores. It also states they do not want the z95 cores. What do you think they're reselling as their z55/z95 cross compatible struts?
The reviews on Amazon for Dorman lifetime struts are not friendly. The word leak appears often. Arnott reviews show as good for their 2 year warranty.
Prior to July 2023 all Arnott z95/z55 have a lifetime warranty. Purchasing after that give you just a two year warranty.
