Just put one on a 2014 SGS about 1000 miles ago. Been pretty happy with it so far. You can feel the difference. Feels like snappier response. Freed up a couple pounds of spinning mass. Bought it from J&P Cycle and it's made by Twin Power (34 tooth). Upgraded to a Hayden chain tensioner while I had it open to reduce chain slap. I have a welded crank so I don't have to worry about scissoring and having no energy absorption that the compensator used to provide.

I'll be installing an Evolution Industries 30t sprocket very soon, before winter is over. My compensator is making a little racket now.
I also have an S&S crankshaft with Timken bearing. No concerns about the swap and the 30t will make things a little more fun.

I'm not sure the spring loaded compensator was meant to reduce crank shock, I believe it was meant to reduce driveline and transmission shock. The concern for me would be transmission gears and bearings along with the primary chain. Maybe they would hold up fine, but just do not know. The primary belt option would be much more forgiving on the drivetrain.

their are a few guys in here that ran em with stock crank, thought was as long as u had ids that would take up some of the shock load.

I ran an EVO Industries 30 tooth in lieu of the stock comp on my 08 ultra for awhile when I was messing around with changing the doggy gearing that was prevalent on the early TC96's. I then changed it out to the original SE version comp and an EVO 49 tooth ring gear conversion to achieve the gearing change. Unless there is a hidden problem lying in wait, it otherwise caused no adverse issues with the stock crank.

I would think you should be ok with a solid sprocket on a stock bike as long as you dont abuse it doing burn outs ,powershifting & or often going close to or @ full throttle when going thru the gears just about every time getting up to cruise speed.
Its when you abuse an HD & or have a modded motor putting out considerably more pwr & trq running a solid sprocket in place of the compensator that would be much more likely to end up with an issue.
