The GFB 200sx Underdrive Crank Pulley has been re-designed to further reduce weight, and more importantly, a steel wear sleeve has been fitted to the oil seal running surface to greatly increase the 200SX crank pulley longevity and eliminate potential oil leaks caused by wear over time. Nissan 200SX GFB Crank Pulley suits SR20DET & SR20DE RWD ONLY.
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.
