1.5” Wheel Spacers

So I installed my 1.5” wheel spacers (hub centric Spacers and wheels are lug centric) and I am getting weird vibrations and various speeds. It doesn’t happen all the time at those speeds which is weird, but around 50, the steering wheel shake is there and at 72, my back seat is shaking like crazy. But like I said, it doesn’t happen consistently. It varies
Before the spacers, it was as smooth as a truck could be.
Any ideas fellas???

 

Your wheels are not hub centric? What wheels are they?

You’re right. Just lug centric. My bad

 

I don’t think you want to run spacers. The leverage you are adding is just exacerbating the balancing issue.

 

Re-check the torque on your wheels and maybe re-balance the wheels.
