?? MMR does not manufacture a dampner?? I believe you are confusing Romac with our company. The Romac Product overall was of good quality, the main problem was that people failed to tighten the bolts and use loctite on them during assembly. This process of tightening the bolts and adding loctite is the same with ATI and most other balancer / dampner companies. We are sorry to hear you MAY be having a issue with a Romac product, should you have a warranty concern or problem however you would need to contact the manufacturer Romac. We are also happy to call them on your behalf if you can give us some more information in regards to the issue you are having.
