The Precision Works E55 5.5 AMG M113K supercharger pulley is a performance-oriented upgrade for 2003-2007 Mercedes-Benz 55K models. Machined from billet aluminum, this lightweight pulley features an 83.9mm diameter to increase boost pressure by approximately 2.5 psi.
Show original supplier description
The Precision Works supercharger pulley is designed to enhance the performance of the M113K engine found in 2003-2007 Mercedes-Benz 55K models, including the E55, CLS55, S55, CL55, and G55. By reducing rotational mass compared to the factory unit, this billet aluminum pulley allows for increased boost pressure by approximately 2.5 psi, contributing to gains in both horsepower and torque. Constructed with a focus on durability, the pulley incorporates an OEM Mercedes-spec Nachi bearing made in Japan. Its 83.9mm diameter is engineered to provide a balanced performance increase while maintaining reliable operation for the vehicle's forced induction system.
