The GFB Power-Up Pulley Kit is designed as a replacement for the original pulleys and increases
engine power and response by reducing the inertial and driven loads, and also by under-driving the
alternator and power steering pump.

GFB recommends that this pulley kit be installed by a qualified motor mechanic, using the Subaru
workshop manual guidelines.

Note: that only the alternator/power steering belt is supplied with this kit, as the crank pulley is designed to re-use the existing factory A/C belt.
