2018 steering knuckle fit 2014?

Found some used 2018 steering knuckles for a Chevy 1500 just curious does anyone know if those would fit a 2014 GMC? thanks

Not unless your 2014 has aluminum control arms.  A 2018 knuckle has different ball joint stud hole sizes that will only fit aluminum or the 2016.5-2019 stamped steel control arms.

 

If you have the forged steel arms they used 2014-2016 you need a matching steel knuckle or you have to get the 2016.5-2019 knuckle and also swap to stamped steel or aluminum control arms.

It does have aluminum control arms. What wouldn't work if it didn't?

 I just edited my post right as you posted lol.

 

If you have the forged/cast arms, they won't fit the 2016.5-2019 knuckle.
