Mine has lasted me two years now. Yeah, it holds. But it's hard to live with on a daily basis. It barks the rear tires, all 4 of 'em, on light throttle take offs. every time. And the pedal effort is horrible, especially with the arthritis in my left foot.
The housing is cast iron, as opposed to the SBC's steel.
The installation takes a special technique to get the disc centered.
At the time we all bought ours, that's almost all that was out there, other than the dual disc pulling clutches.
The SBC is a better choice in my opinion, in a side-by-side comparision. And it's backed by a warranty and service that cannot be beat. It installs easily. It has near stock clutch pedal effort.
I never did get the time or money to change my clutch out, perhaps that will change this year. It'll be either an SBC or a Mitchell pulling clutch.
Do I regret getting the Donnelly Re-Engineered Sachs? No. It's served me well, and I'm grateful. But I see an opportunity to move on to something that may fit my needs better... .
Gitchesum, "grabby" ? a "little grabby" ?
The only two things in the world that'd be grabbier than a D. R. E. Sachs would be a male teenager in the Playboy Mansion, or an octopus in a swimming pool full of bowling balls.
