If your springs don't stay in place, REPLACE the springs!

 

They're noted as Isolators too, keeps from causing vibration and sound. The springs are not broke they just slipped off center as I said there is nothing but a small flange in the center to keep them in place (which is clearly not enough on its own). I was looking at different insulators/isolators and the type that I have was a simple flat washer but the one that they use in this , it fills up the hole of the spring more so that would probably work on the top to keep it from slipping off center. The flat washer that came with my kit is not enough. I pretty much did mine the way this shop did it accept I didn't remove that bottom boot I just slipped the flat washer around it, but you can't do that with the other style insulator you'd have to take that boot off. I didn't remove the air compressor. I still use mine for airing up tires. I don't know, I may just put it back to airbags, I've got new ones in a box, I just didn't like it going down and waiting for it to air up but mine were leaking though pretty bad. When it warms up I'll jack it back up and do one or the other. Put it back to airbags or buy that other isolator/insulator see if that fixes.

 

"the springs are not broke" Never assume your springs are junk, only with a break! Simple test on coil springs--> frame lift until both wheels are off the ground. After you have both rear wheels off the ground, rear axle hanging, frame secured with jack stands, crawl under and grab the coil springs and try to move them. If you can move them, they are junk!

 

Not worried about the springs. They work fine, problem is the rubber insulator is not the correct style. The ones that came with mine don't keep them in place. I found the correct ones on Amazon for the top.

 

I'm not worried about your springs either since I don't ride on them. Without insulators your springs should stay in place, even when fully extended! That's how "comfort ride coils" work. Driving down an uneven road can extend the suspension to max, in the meantime the coils should follow the extension to ease the contraction. Any addition of spacers will increase the firmness on the ride. Find the right replacement coils or go back to the airbags.

 

Thanks. I already figured out what the problem was. Wrong isolators. The springs will not stay in place without something to hold them there despite what you claim. I had them centered when I installed them and the right one slipped off, which I figured it likely would since there's nothing there to keep it from moving. The correct isolator will hold it centered by the looks of them. The style that I have installed now is nothing more than a washer and that will not work.

 

Yep - that raised bit in the center is not huge (maybe a half an inch) but it is enough and is needed to keep the coils centered on their seats.

 

After the new insulators springs still move, research: spring rate.

 

My 6” FabTech coils were different in size/length and clearly marked driver and passenger. Here is the insulators I used top and bottom.
Zero movement and everything fully functional in place and I’ve taken corners quickly trying to get them to move.

 

Test them by going airborne.
