SPC UCA Specs

Got my 2021 sport extended cab with Fox 2.5 non res. coilovers, SPC UCAs and 275/70/17 BFG KO2s aligned, and its still rubbing on both front mud flaps. Told the shop about moving the LCA forward first, but he said he could not get the other numbers by doing that. The SPCs were at setting D. These are my numbers, Camber LF 0.2 RF 0.1 Caster LF 3.5 RF 3.3 Caster LF 0.08 RF 0.05 This is mostly a daily driver. Any idea what to shoot for to stop the rubbing on my mud flaps. Thanks in advanced.

 

There’s a point when adding caster using upper arms actually causes more rubbing. If the lower eccentrics are maxed, that’s it.

Take a photo of the rear lower control arm cams.

 

I can't help with your question, but that's a good looking truck!

 

He had moved the indexing plate on the PS only. The DS is at D don't know what the PS is but think its at E.

 

Make sure they moved the SPC index plates the correct direction, your picture makes it look like your wheels are really far back in the wheel well.

 

I think he moved the PS to E ?
