Designed to slow down the power steering pump to prevent it from overheating in racing conditions, this pulley will quickly pay for itself by not just saving your pump, but also your weekend at the track.

The pulley is fully balanced and 4" OD at the belt tooth (a 27% reduction), the minimum OD to be BSR legal. Its weight has been optimized to be one of the lightest under-drive pulleys on the market today.

Made from high grade aircraft quality 2024 aluminum, which is far superior to the lower quality pulleys on the market that are made from a lower quality material.

An additional benefit is increased power and torque across the entire RPM range.

The kit comes complete with the crank pulley and a new crank pulley bolt. Fits all 986, 987, 996 and 997 except 997S 3.8L or Turbo or GT3 or DFI (2009 on). A boss on the front of engine case will need to be cut down slightly to clear the smaller pulley size. A smaller belt is needed and can be purchased separately.
