K20A(EP3) Light Weight Front Pulley KIT
Developed to give lighter and sportier engine characteristic. By reducing the overall weight (and inertia) of the pulleys, and by modifying the alternator pulley ratio to take advantage of the more sporty use, the burden on the engine is reduced helping to improve acceleration performance. A standard length belt for the AC kit and shortened belt for the AC less kit is provided. Installing with a new belt is important to help improve the running in process of the new pulleys. A good affinity material is used on the oil seal face of the crank pulley to reduce friction improving sealing and to reduce wear. The hexagon socket design of the original crank pulley is retained so that Honda's service tool can be used when loosening or tightening the crank pulley bolt.
A. 2 pieces structure
A good affinity material is used on the oil seal face of the crank pulley to reduce friction improving sealing and to reduce wear.

B. Duralumin A-7075

CAUTION: TODA Racing has done many checks and calculations for its light weight pulley kit so that the revised ratios allow the charging system to supply the basic amount of electricity required to run the engine under most conditions and charge the battery. But please understand that in worst case situations the battery may become drained.
