Kartboy Crankshaft Pulley weighs in at 1 Pound. A good bit lighter than stock but not light enough to throw a CE light. Free up a little crank HP and get some KB Bling.
NOTE: Pulley will not fit unless Subaru part number 12339AA010 is installed on these applications
2015-2017 Crosstrek

Johan –
Great product that helps with lowering the rev-hang (noticeably improved throttle response compared to stock pulley). Makes rev-matching/heel-toe much smoother/easier.
Makes a slight whine (like a supercharger) up to about 3,000rpm – not a major issue (you get used to it).
