Developed for the extreme power enthusiast, the RCM Light Weight Crank pulley reduces the crankshafts reciprocating mass massively improving acceleration and engine response as well of giving your engine the Roger Clark Motorsport identity and seal of quality.
The Subaru OE crankshaft pulley weighs in at 2.6Kgs, with the RCM light weight pulley weighing in at just 752grams, saving a huge 1.85Kgs on the engines rotating bottom end.
Constructed from the highest quality aluminium, this pulley has been manufactured utilising the latest CNC techniques as used by today's leading Formula 1 teams.
After machining, pulleys are anodised using the latest military specification.
Our kit retains the standard pulley diameter which allow the use of the existing auxiliary drive belt to ensure power steering and alternator speeds remain standard.
Please note that it is still possible to run air-conditioning with this pulley.
