You all know that more clutch pressure means a stronger clutch, but clutch pull also becomes much heavier.
Since a long time AIM Corp. (Advanced Innovational Machinery Corporation) offers Variable Clutch Performance Kits to upgrade Harley-Davidson the stock clutch and eliminate unnecessary heavy pull.
They are cost effective ways to upgrade a stock clutch without any modifications. Now, AIM offers the first “sliding lock up” system released in the industry for an easier pull (30% lighter during low RPM) and creating 120-130 lbs of extra clamping pressure at 4000 rpm, or 40% more clamping force.
Will directly fit into the ’15 Ultra Limited Low/Electra Glide Ultra Classic Low models’ with the new narrow primary cover. Bolts into the Twin Cam Assist and Slip ( &S) clutch kit. Also fits ’13 and up Tri-Glide and ’13 and up CVO models. Slider weights design will fit behind stock, 103 and 110 derby covers, with no modification needed. More info at AIM Corp. 714.848.3030.
Sounds like just the thing for the S&S T143
