Overview

The MODE Auto Concepts GFB Lightweight Underdrive Crank Pulley is a performance upgrade for Mitsubishi Evo 4-9 models. Constructed from 6000 series aluminum alloy billet, it offers a significant weight saving of 1.4 kg over the factory pulley. This pulley under-drives accessories by 20%, reducing parasitic losses at high RPM while improving throttle response, especially off boost.

The kit includes the necessary serpentine belt and is designed for easy installation, requiring no specialized tools and taking approximately 30 minutes. The engine will feel more willing to rev with the installation of this under-drive crank pulley.
Show original supplier description
The GFB Lightweight Underdrive Crank Pulley from MODE Auto Concepts is engineered for Mitsubishi Lancer Evolution IV-IX models (1996-2007). Constructed from robust 6000 series aluminum alloy billet, this pulley offers a substantial weight reduction of 1.4 kg compared to the stock component, contributing to a more responsive engine. This underdrive pulley system reduces parasitic losses by under-driving accessories by 20%. This modification is particularly beneficial at higher RPMs, leading to a noticeable improvement in throttle response, especially when off boost, and a more eager feel as the engine revs. The effect is comparable to the difference in performance experienced on a cool evening versus a warm day, or with the air conditioning system disengaged. The kit comes complete with the required serpentine belt for a straightforward installation process that can typically be completed in about 30 minutes, without the need for specialized tools. The product is compatible with a wide range of Mitsubishi Lancer EVO IV-IX variants, including 1996-2007 models with various engine power outputs (e.g., 194kw, 195kw, 202kw, 206kw, 214kw, 246kw) and drivetrain configurations (FWD Sedan, AWD Sedan).
