Sulastic shackles?

[Lifted92]

I was curious if anyone has tried the sulastic shackles and whether they help and/or how durable they considering that they are rubber springs? I have an add a leaf lift and they should help with the jumpiness.

I want to try them on my 99 suburban and 05 3/4 ton avalanche

My 1/2 ton rides like a 3/4 with that extra leaf and supposedly they help alot

I like them. Have had them for probably a year now, and think they helped quite a bit. My wife and kids noticed also when they rode in it. Put some on my Dads F250 also. They will give you refund if you don't like them. I tow a 9000 lb toy hauler and it tows really nice with the shackles.
