Help with Cognito uca and Fox 2.0 Coilovers

[SupaFly209]

I've got a 2015 Sierra. It was once lifted on a 7" Rough Country lift with FTS boxed upper control arms. Now I've brought the truck back down to stock. Leveled on Fox Performance 2.0 coilovers. I wanted to continue to use the FTS boxed uca but I was having clearance issues. With the stock knuckles, stock 20 inch wheels and FTS uca......my wheels were rubbing the uca. The lip of the inner wheel got scratched up pretty good coming out of my driveway during a test drive. Now my question is.... has anyone used the Cognito uca with the Fox 2.0 and the 20 inch wheels? I really want to replace the stock uca with an aftermarket one to improve ball joint angles. I contacted Cognito and they told me that their arms with the Fox will certainly work with 17" and 18" stock wheels but are unsure if they'll work with stock 20" wheels. He mentioned those Cognito uca were designed in 2008 and they have no data on if they'll work with with stock 20's. I've searched and found guys using ready lift uca with 20's. But I'm asking if they'll work with Cognito or any other arms. I know for a fact they won't work with FTS arms. Please help and Thank You for your time.

I have Cognito UCAs on my 15 Sierra with Boss Halo coilovers and the stock 20" snowflake wheels.

My coilovers are set at 2" and I have a Zone 1.5" body lift.

Before I put the Cognitos on I had RC UCAs and had the same issue as you.

At that time my front was set to 3", so i think the higher you go, the more it pulls the wheel in.

At 2" on the coilovers it does not make contact anywhere. I'm running a LT285/60R20 tire.

I had Reklez UCA's with stock 20" LTZ wheels and Fox 2.0 coilovers on my 2018 when it was leveled. I was running a 285/60/ 20 tire also. Look into Reklez , as beefy and nice as cognitos. I'm now running them with the CST 4 1/2" lift.
