I've got an annoying problem with my springs dancing around in my aftermarket coil buckets. Sometimes they get kicked to a spot where the spring rubs on the sides of the bucket and makes a nice crunching noise. I wrapped some heater hose around the top of the coil, and it worked perfectly, it kept the coil nice and centered, got rid of the metal to metal contact, and last time I checked they were holding up. But its time for alignment again, so it would be a good time to do something more permanent. Has anybody used some kind of coil insulater that wraps around the top like a cap? If so who made it? Thanks, and thanks to all that replied to my last question about worn heims, it turns out the heims are worn, I just couldn't tell because my shocks are stronger than me but when I fully extended them I could see/feel some play.
