Mercedes-Benz A45 CLA45 GLA45 AMG Performance Underdrive Crank Pulley BILLET ALUMINIUM

Specifically designed for the Mercedes-Benz A45, CLA45 and GLA45 models, our performance underdrive crank pulley replaces the factory heavy cast-iron pulley with our light-weight underdrive pulley. Our underdrive pulley slows down the rotation of the engine accessories, allowing for more power to go to your wheels. As our pulley is also significantly lighter, it allows the crank to spin easier - once again giving you more power. After installation, you'll have an increase in performance, throttle response and improved fuel economy.

Our underdrive pulley kit comes with a High-Quality Gates belt, and a New Genuine Mercedes-Benz Crank Bolt.

Our pulley is CNC manufactured from billet 6061 aluminium; we then anodize them black for that neat look. The pulley also has a hardened stainless-steel ring pressed onto the hub to allow for a better & stronger seal between the pulley & the crank.
