There’s really no need for a dual shock set up anymore. The only time I see them is on off road vehicles and they’ll use a coil over shock along with a bypass shock.
My opinion is you get what you pay for when it comes to shocks. And the rings true especially when you’re off the pavement.
The shaking you’re experiencing is not due to you requiring another shock. You have another problem problem. Wheels need to be balanced, alignment, something with the leveling kit is off. Not installed properly, not tightened, etc.
I did not mention any worn suspension or steering components because the truck is still brand new. But those can also cause a shaking feel while going down the highway.
