Well, I finally got around to installing my Centramatics last week. They work as advertised, which is to say they work great. The only problem I had was bolt size. Centramatic assured me they would fit my truck, but the holes that lined up with my bolt pattern were 9/16 and my studs are 5/8. There were 5/8 holes in the Centramatics also, but they didn't line up with my pattern. A quick drill out of all 16 holes to 5/8 i. d. and they went right on.
The only other thing I'm not too happy about is the noise. My truck has 4" pipe with no muffler, it's pretty loud as most of you "straight pipe" guys know, but I can STILL here the balancers up to around 25 MPH. They sound like loud baby rattles bolted to the front wheels. I'm quite happy with their performance, but if I had to do it over I would go with the BalanceMasters which use liquid instead of a solid media for balancing. I'm sure the BalanceMasters are much quieter, if not silent.
