It's a SE adjustable tensioner, it should be in the Screamin' Eagle Catalog. There are a couple threads about it, with part numbers and cost (around $150), etc.
Here's a pic I saved of it...
I purchased a Hayden just before I saw this one. Glad I stuck with the Hayden.
While all second hand...... on the Harley Tech Talk forum, a guy installed it and didn't like it at all. He said it was very noisy... He removed it.
Just an FYI......

It's for high power race applications.
The Screaming Eagle Manual Primary Chain Tension Adjuster is a real benefit in those aggressive racing situations where frequent drag racing starts and high rpm speed shifting are part of the riding experience. Ideal for bikes equipped with big displacement high performance (100hp+) engines that are regularly used for track-day drag racing; this Screamin' EagleŽ Tension Adjuster permits manual selection of primary chain tension.A direct replacement for the Original Equipment automatic version, this anodized billet aluminum adjuster allows you to fine-tune the settings, and lock the position when the freeplay is properly set. The manual adjustment locks the chain tension in place to prevent the chain from adjusting during severe shifting. Kit includes required mounting hardware.
