Product Description

Complete Pulley Kit

This pulley kit replaces the alternator, the water pump pulley, power steering pulley and the main pulley. They free up horsepower (With our SR Underdrive Power Pulleys our Project RX-7 gained 14 horsepower.) due to being 45% lighter than stock and by underdriving the crank shaft pulley, alternator, power steering and the water pump to keep down the chance of cavatation.Our SR pulleys are also larger than the competition's pulleys so the fan belts have a larger surface contact area ( so our pulleys _won't slip_ on the fan belt causing your rotary engine to overheat which is very common) Available in anodized hardcoated lightweight and strong 6061-T6 billet aluminum for years of trouble free use. Complete kit with everything needed. A very easy horsepower increase and nice looking addition to your Mazda RX-7. Simple to install with hand tools.

( Note: Our SR pulley kits do not require you to remove the crank shaft hub in order to install the main pulley ( like some other pulleys ) which is a very _difficult_ thing to do.)

Our Underdrive Pulley Kit Includes: Alternator pulley, power steering pulley, waterpump pulley, main drive crank pulley and all needed hardware.
