The Beatrush crank pulley replaces the factory main pulley, the lightweight unit improves acceleration by reducing the rotational mass of the stock unit by as much as 4lbs.

Weighs 1.5lbs, over 4lbs lighter than the factory pulley for improved engine acceleration.

EASY INTALLATION FOR 08+ WRX, STI! as this piece has no belt groove in the back end compared to the competition.  2008 WRX's and STI's have no AC belt tensioner, so the rear belt keeper is not needed.

Works on:
WRX & STI 02-09
Impreza RS,TS 93-01
Legacy GT/Outback XT 05-09
