Strut cartridge install (is this correct for Sports?)

[KenC]

Here is my Bilstein Sport in the housing:


Is this correct? What are the other pieces that came in my box with the struts?

im pretty sure thats right the white ring deal holds the boot down you slide it on therea and then slide the boot over it

Jesus christ man, that picture is huge.

You probably got the collars for 45mm struts (external threads on the strut) and 51mm inserts (which have internal threads on the struts). Just use the ones you have on there - I like to tighten them down with a pipe wrench. The plastic rings both serve the same function, but one is for 45mm struts (grey, IIRC), and one is for 51mm struts (white). They go inside the bottom of the blue boots and hold the boots over the shock collar.

My bad, I was in a hurry to post it.

Thanks for the info on the collars and whatnot.
