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
