[Contact Us to Order this Product!]
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 is a 16% reduction. Its weight has been optimized to be 1/2 that of any other under-drive pulley on the market today. An additional benefit is increased power and torque across the entire RPM range.
A boss on the front of the engine case will need to be cut down slightly to clear the smaller pulley size. Comes complete with the crank pulley and a new smaller belt.
