861 vs 891 vs Superflex Coils for rear weight

Go 861's if you've got a lot of weight in the back, carry a lot of gear, or like a good raked stance. I've got 861's and my rig is about as heavy as they come at this point. It sits good unloaded, and even with a FULL load I still sit with a slight rake. In my opinion 861s are the only spring up to the task of carrying weight. My only suggestion is to wrap the top progressive coils in "spiral cable wrap". I had a terrible noise from mine around 40mph where the coils would vibrate and resonate off each other. I put some of this on yesterday and the noise went away! It would have been so much easier to do off the truck though.

I just ordered 861s, extended rear brake lines, and some 20mm spiral cable wrap. Thanks a bunch for the tip about vibration. That would have driven me nuts. This is a work truck so everything needs to be right.

Ive found other threads on vibration after installing 861s. But it seems no one can identify the cause. If cable wrap really solves the problem we should spread the word and save people a lot of headache.

This is good info since I am looking at rear coils again, and 16mm spiral cable wrap, apparently, if going 261
