Rubicon Express Tri-Link upgrade kit

I called up Rubicon express about the lift that I own. I asked him about the binding that takes place in the rear of the jeep. He suggested to me a Tri link upgrade for around 500. Any thoughts on this rear upgrade?

I'm assuming I can install a 4 link in the rear but would have to re-weld the upper brackets back on.

(Trying to avoid paying 3k on another lift in the future)

Thank you guys,

You're binding because you are running radius arms. You can install this single rear upper arm to help but, the amount of flex you'll have will still be limited to the length of your shocks. Being that you still have to run a track bar, I would just opt for a standard 4-link setup but, that's just me. Your main lowers are fine, you just need uppers.
