If you're looking to give your Mitsubishi EVO VIII or IX a little extra edge, check out the new Under-drive Crank Pulley from GFB. This isn't just another aftermarket part; it's a serious upgrade that can change the way your car feels on the road. Made from tough 6000 series aluminum alloy billet, this pulley is not only lightweight—saving you a solid 1.4 kg compared to the factory version—but it also maintains the strength and reliability you need when pushing your car to the limits.
One of the best parts? The kit comes with everything you need, including a serpentine belt, and installation is a breeze. You won't need any fancy tools, and if you’ve got a bit of mechanical know-how, you can get it done in about 30 minutes. The accessories are under-driven by 20%, but don’t worry, you won't lose any performance at low RPMs. Instead, you’ll notice a reduction in parasitic losses when you’re revving high, which is where it really counts.
What does this mean for your driving experience? Well, the difference is pretty noticeable. You'll enjoy a sharper throttle response, especially when you're off boost, and the engine just feels more eager to rev. It’s like the difference between driving on a cool evening versus a hot day, or feeling the change when you switch off the A/C. It’s that kind of improvement that makes your EVO feel alive.
Fitment:
Also fits Mitsubishi Lancer models from 2003-2006 and 2008-2015. If you're serious about enhancing your ride, this GFB Underdrive Crank Pulley is definitely worth considering.

It all started with the passion of John Adrian to create something that other aftermarket parts cannot produce. Most parts he encountered are either of low quality and are made out of inferior materials.
He decided to take matters into his own hands and started designing, testing, and developing parts that would help improve the performance of his vehicle. Using his own car as a personal testbed, he created products that other enthusiasts later noticed, which has become the start of Go Fast Bits.
