lowering kit problems

Jeremygmc5 · March 17, 2019

Hey guys i am new to the forum let me induce my self my name is jeremy and i drive 2018 sierra double cab 4x4 sle which i am looking into lowering

MY problem is i ordered the 34170 mcgaughy's kit and when i bought it they didnt specif that i need to have the older style cast arms in which i have the stamped arms

so would i be able to swap just the lower arm to the older style cast? or do i have to switch both arms?

I'm struggling to overlook why you'd lower a 2018 4x4, but I think that the only difference on the control arms pertains to the uppers. 2017 and up uses stamped upper control arms. 2014-2016 is cast. Lowers should be the same. Either way, you can buy a set of upper control arms for a 2014-2016 and that will bolt right on.

No, return it and get the correct kit for stamped steel arms, the stamped steel lower control arms on the 18 use a larger, heavy duty ball joint, same as the aluminum arms.

Is there an ability to specify which? I'm under the impression there is not, which is why I said to change the upper control arms out.

yes, they make a kit for each control arm style. aluminum and stamped steel are the same kit. and it's the lower control arms that have the different ball joint sizes.
