Variable Pressure Clutch
I currently have a SE spring on my 2010 Streetglide. Was thinking about adding a VPC to get better grip. Does the Variable Pressure make the hand lever pull any easier or will it actually get harder? Is the AIM any better/worse than the others? I believe from what I have read the Harley model is actually mfg'd by AIM.

The VPC does make the pull easier, some say that it is harder at high rpm's but I couldn't tell the difference. I used the AIM on a 2000flht and the Harley one on my 2013flhx, no difference between them.

I just had one installed on my 2010 SG back in Sept. AIM has various models depending on how light or heavy you want the clutch pull to be, and that is also dependant on the weight of the clutch spring being used. I had one put on to hold my clutch from slipping on my 107" build and it is fantastic at doing its job. My clutch no longer slips and the torque is incredible now that all the power is transfered to the wheel. The pull is a tiny bit lighter than stock but that is because I used a much heavier spring. I could've gone with a 40 percent lighter pull but not with the spring I selected. I wouldn't hesitate for a minute to do it again. Good luck with your decision.

Just went through this myself. Read my thread and it may give you some insight.

If the clutch spring you currently have is working fine then it should be possible to install a lighter spring with an AIM. It applies increasing pressure, as engine speed increases, hence at low road speeds a lighter spring will give you a lighter pull, the AIM bob-weights doing the rest. Their website gives details.

Just installed my VP95LT yesterday. Do it! The heavier clutch spring alone was disastrous for me, though mine was a Barnett and not the SE. The Barnett exerted 450 psi, and components around the clutch just aren't made to withstand that kind of pressure/pull.
Good luck sorting it out.

I used the VP95LT in tandem with the stock spring, and it has given my a clutch pull that seems to be slightly lighter than what the stock set up gave me. It's close though. It's SO much more pleasant on my left forearm, and you know how much easier it is on the motorcycle.
