The PowerBond Unit also sold under Pioneer brand & PBM is the only damper I use other than ATI. It's my "budget" choice... have never had a single problem with one, even in 700-750 HP motors, including circle track use. I've probably used 35-40 of them.

I've had several Summit SFI dampers fail (slip).

When I did a search that one never came up. This is the one I ordered
http://www.summitracing.com/parts/SUM-B64277/ is this the one that slipped or was it the cheap one? I don't want to screw up your work.
It's been shipped but I can order a different one and send it back.
What do you think.
