Crankshaft Pulleys

Easy installation
Better throttle response
Retains original belt
Improved MPG
Best and most economical entry level modification

This pulley kit yielded an improvement of around 6-7whp and around 9ft/lbs of torque. Both the lighter construction and smaller size helps improve power. Comes with belt and pulley. This is a custom ROAD/RACE CNC machined crank pulley. It is made of aircraft grade aluminum and weighs just .5 lb , stock pulley weighs more than 4 lbs. and robs HP from the engine just to spin it. Just like a light flywheel, throttle response will be greatly improved by reducing parasitic drag on the crankshaft. Research has shown that 2.7 HP is gained from every pound of weight reduced from the crankshaft. Installs in minutes and uses original belts. Professional installation is not required, however we do recommend using an impact gun to remove the main crankshaft bolt.
