Without trying to sound clichéd, the GFB SR20DET lightweight underdrive crank pulley is new and improved! Of course, it can't be both new AND improved, so we'll go with improved!

It has been re-designed to further reduce weight, and more importantly, a steel wear sleeve has been fitted to the oil seal running surface (shown below) to greatly increase pulley longevity and eliminate potential oil leaks caused by wear over time.

Suits SR20DE and SR20DET engine in rear-wheel drive configuration only.
