Reports like this kept me away from aluminum ds and led me to QA1 CF. Glad went that direction.
I have no choice but to run one, I'm making nearly 900whp.

I've tried Gforce, DSS and Qa1. They all vibrated on the freeway, tried rotating every position possible. Back to stock, which has me concerned with the blower and sticky mickeys

I'm boosted. And I vote to keep the stocker. And just use a drive shaft safety loop.

I have the QA1 on my 2018 it is perfect!

Note: I did have some very minor vibration @100 MPH. So, I clocked it 180 on the pinion end only and the minor vibration was completely gone.

Did you clock the pinion only or the pinion and the spacer
