| Product Description New from GFB is the Under-drive Crank Pulley for the Mitsubishi EVO 
IV through to IX. Like all GFB pulleys  the material used is 6000 series
 aluminium alloy billet  which nets a large weight saving of 1.4 kg over
 the factory pulley  without sacrificing strength or reliability. 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.Like
 all GFB lightweight under-drive pulleys  the improvement to the car is 
felt in the form of sharper throttle response (particularly off boost)  
and the engine feels more willing to rev. A useful comparison is the 
difference between performance on a cool evening vs. a warm day
