Hey y'all, bit of a newbie here. I'm currently in the process of swapping out my air struts, Ive ordered KYB struts, RSR springs, and KYB strut mounts, bump stops and bellows.

I need a little assistance specifically with the rear strut mounts. I've noticed there's no kind of rubber gasket/seal on the rear strut mounts like there are for the front (which include a rubber bellow).


The rear strut mounts did not include any sort of rubber fittings

Is there supposed to be metal-on-metal contact with the rear struts like this or is there a grommet/gasket piece that I am missing? I've been searching around for days now trying to find the name of this part and if it's even needed. Any sort of help would be super appreciated. I want to do this right!

 

Okay, looking around at other assemblies it looks like there's some kind of Insulator that needs to be between the strut mount and the coil spring, but I cannot for the life of me find the correct part. Would the OEM 48257-50020 work in this case?

 

4825750020 is the correct part for the Rear,

 

Thank you so much for this. Just to confirm, I'll need to get 48258-50020 as well right?

 

I did my rear struts 3 years ago so my memory may not be perfect but I think it's just a thin plastic "sheath" that wraps around the top part of the coil. It doesn't amount to much so I wouldn't think it's critical.
If you have the OE rubber insulator (4525750020) you prob don't need it. Just my 1.5 cents...
