2006 - 2012 BMW 135i / 335i N54 Pulley Kit NST53000K Crank Pulley Only

The NST BMW N54 Crank Pulley is designed for owners looking to reduce weight and increase the throttle response of their engines. 

This OEM diameter pulley will neither underdrive nor overdrive the associated accessories, yet leads to great throttle response, and improved horsepower and torque numbers. 

The NST PS-Lite replaces the plastic OEM BMW power steering pulley with a much stronger, lightweight, aluminum piece. 

Each kit is CNC machined from 6061-T6 aircraft quality aluminum, and tested for tight machining and balance tolerances. Every NST pulley is hard anodized for exceptional durability and is available in a choice of colors. ​AVERAGE WEIGHT COMPARISONS
