I have the Centramatics on my 2006 Ram. I had to special order my truck and it took 6 months to deliver it. During that time I bought some accessories. When truck came in it has a balance problem. installed Centramatics and problem went away. than I took off all the wheel weights and it was still perfect.
this truck was my Fulltime driver so I changed out snow tires for a couple winters (I mount my own). at 50K mile mark I bought new tires, again, no balance. Every once and a while I might have a little vibration when I first start driving, but that goes away real quick. Love them and would recommend them to anyone. (but $200 would pay balancing around 20-30 tires).
