Lightweight Pulleys Kit with AC

The Toda Racing Lightweight Pulleys Kit (with AC) is engineered to enhance the performance of the Honda K20A engine. This kit focuses on reducing rotational mass and inertia by utilizing lighter pulleys. Constructed with attention to durability and performance, the kit incorporates a special affinity material on the oil seal face of the crank pulley. This material aims to minimize friction, improve sealing capabilities, and reduce wear. The kit comes with a shortened belt, and it is recommended to install it with a new belt to ensure a proper running-in process for the new components. The design also retains the original crank pulley's hexagon socket, allowing for the use of Honda's service tools for installation and removal. This pulley kit is specifically designed for the K20A engine, found in the 2007-2013 Honda Civic Type R (FD2). The part number for the AC version is 13810-FD2-HAC. It's important to note that while this kit is verified to produce sufficient power for the battery under most conditions, during prolonged idle periods, the generated electricity might be less than required. Therefore, caution is advised to avoid using multiple electrical devices simultaneously, such as the air conditioner or headlights, to maintain adequate battery charge.
