I asked this on another forum with no response. Hopefully someone here has a legit answer. Has anyone installed 15-20 Upper control arms yet on a 2021. I am waiting for my Bilstein 6112 / 5160 and a set of BDS UCA's to come in. Are a set of BDS UCA going to beneficial? I have a 2021 STX with a crew max short bed 4x4. Has anyone even installed aftermarket UCA's yet or am I going to be the Guinea pig?
