GFB Lightweight Crank Pulley - Mitsubishi Lancer Evolution 4-9
The GFB Lightweight Crank Pulley allows for sharper throttle response (particularly off boost), as well as providing a large saving of 1.4kg of rotating mass over the factory pulley, without sacrificing strength or reliability!
Like all GFB lightweight pulleys, this one begins life as a single 6061 aluminium alloy billet, and is then precision CNC machined to exacting tolerances. GFB then anodize it black for a stealthy appearance and superior wear resistance.
The kit comes complete with the required serpentine belt, and installation is dead easy – no specialized tools are required and it can be done in as little as 30 minutes. The accessories are under-driven by 20%, which does NOT compromise their performance at low RPM, but does help reduce parasitic losses at high RPM.
Sold individually.
GFB Lightweight Crank Pulley features:
