The Zipper’s MUSCLE 128″ Kit for the 114-117″ M-8 is the most powerful top end and cam kit we’ve ever produced for a production motorcycle! Our Red Shift 552 cam delivers HUGE torque as soon as you open the throttle, and carries it across the RPM range to provide instant acceleration from any RPM. #REPOST @americanclassicmotors 152HP/ 155TQ with power still climbing at Redline. #fxlrs #fxlr #2020lowriders #americanclassicmotors #harleylowrider #harleylowriders #softail #softaillowrider #softaill

The all-new Red Shift Cams® RS528 Cam for Gen2 Non-VVT M8® engines, in a CVO ST 121", idling and running on the dyno. An RS528 in a 2024 117" will run circles around a stock CVO ST 121", but when they have the same cam, the 121's added displacement and compression really shines, and stands above the 117"! https://bit.ly/4fZUI2R | Zipper's Performance Products
