Guess they didn't reinvent the wheel after all? Bummer.
Maybe, Maybe not. It is obvious that Synergy has had some issues with some but was it just a bad batch or is it the version they chose to use. But they are not the only ones using them either. Rancho, Clayton, ARB/OME, and Mopar are using versions of DDB as well. The Mopar ones look interesting to me as they have what looks like a larger inner sleeve that is knurled to increase grab to the control arm bracket.
