    Variable pressure clutch, wear ring, and hardware
Variable Pressure Clutch is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from I am glad I bought this Variable Pressure Clutch ! After installing a SE 103 stage two kit in my 2011 96 ci FLHR I liked the extra power the motor had and the way it ran but I *did notice* the extra effort it took to pull in the clutch lever with the stronger SE clutch spring that came with the kit and was installed by the dealer. I could notice the extra tension on the clutch to pull the lever in especially in stop and go traffic around the city here where I live. So, I decided to use the Variable Pressure Clutch (VPC) in my 2013 Ultra Limited (FLHTK) when I recently had SE 255 cams and SE adjustable push rods installed instead of the stronger SE clutch spring, or converting to a hydraulic clutch instead of the cable that the bike came with. This Variable Pressure Clutch was the best move I made and no clutch slippage ! I used the factory clutch spring that my FLHTK came with, (very easy to pull in) in my opinion even easier than the pull of the new Rushmore Hydraulic Clutches. I also noticed it does seem to shift easier when traveling into the upper gears and also go into neutral easier as the other have already mentioned in the other reviews. This was a very good choice for me and it was well worth the price to be able to keep my *easy to pull factory clutch spring* in that my bike came with. HOWEVER; The gasket that came with the VPC started leaking after a couple short trips to the store (about a 100 miles or so). I have the Live to Ride 103 Derby Cover and it was a Saturday after the dealer had closed the service Dept. till Monday. I wanted to ride Sunday so I took the Derby Cover off, cleaned it, and clean the gasket good and used RTV gasket sealer on both sides of the gasket and put it back together. The oil leak stopped. It's been a couple weeks now and about 500 miles later. No leak. The serving Dealer did offer to change gasket for me but agreed the way I sealed it with the RTV sealer it would be fine till the next service is due for an oil change. Again, I am very happy with the VPC but, Harley Davidson does need to improve the gasket ! BTW, I read these reviews prior to me making my choice and purchasing a VPC. I Hope this helps others as it did myself.

Rated 5 out of 5 by from Easy upgrade I upgraded my 96" to a 107" with TW-555 CAMs, new lifters, CAM plate, oil pump, push rods etc and based on feedback of a few local builders I upgraded to the VPC. After putting 2K miles on the bike since I am glad I upgraded the clutch given it is a LOT easier to shift, find neutral and holds strong even with 100+ HP.

Rated 5 out of 5 by from more power to the ground It does what they said it would do. With a stage4 it puts more power to the ground, and while traveling down the road. Its awesome, what can I say its Harley Davidson.

will this work with 2008 ultra classic with hydraulic clutch?

Will not fit 2016 FXSE ?

If I read the fitment correctly, this item will not fit my 2016 Pro Street Breakout? Can I perhaps downgrade my S&A clutch to an older unit and then add this?? For me, the benefit of lower clutch lever feel, while still being able to handle higher output, outweighs the benefit of smoother deceleration. Please advise. Cheers Mike
