Is it really necessary to have this on? Who here with rear lift coils are still using it?

 

I still use mine.. I just trimmed it down super short. Essentially it's a cheap spacer for me.

 

remind me what the coil isolator is??? Its not that cone thing in the coil is it. If so I tossed it when I put in the Revtek. Hopefully thats what your talking about. Dumping the cone, wont cause problomes will it?

 

Left mine in, heck free 1/4-1/3 of lift why not leave it there
