Lightweight Under drive Pulley is made from 6061-T6 aluminium. Offers improved HP & TQ by reducing drag from the power steering pump, A/C, water pump and alternator.
Pulley outer diameter: 123mm (measured from ribs to ribs)
Increase your engine output by reducing the draw of the engine's ancillaries ie the power steering pump, Air Conditioning, water pump and alternator by slowing them down and reducing the horsepower they use.
Underdrive pulley is one of the cheapest returns for the money spent when it comes to actual performance and horsepower gains for track and street use cars.
Installation tool (wrench) included, new OEM crankshaft pulley bolt is recommended but not included with this product.
Note: In order to accommodate the smaller diameter pulley, the timing boss on the engine case
must be shortened using die grinder or similar tool (see link for instructions below).
