/93+ RX-7 Super Light Weight Main Pulley/

We offer different pulley kits for different applications.  All our pulleys are made of CNC machined 6061 T6 aluminum to reduce rotational inertia and they are made to under-drive the stock accessories to give more horsepower to the rear wheel.  All configurations of pulley kits are extensively tested both on the street and race track to ensure for reliability and performance.  The pulley kit is featured in the Sport Compact Car magazine.

Main Pulley kit: The power pulley under-drives all the accessories by 25%.  Our pulley is super light weight at 365 grams (0.8 lbs).  Others weight about 560 grams (1.2 lbs)  So our light weight pulley further reduces the rotational inertia and gives you more power to the rear wheel.  The power pulley kit is a bolt-on and it comes with stainless steel mounting hardware. The complete kit comes with pulley and two belts to work with stock air pump, water pump, power steering pump, and A/C compressor pulleys.

New: 2 Piece Pulley Kit: The pulley kit comes with alternator, water pump pulley, and a belt which is designed to be used with the stock main pulley and it eliminates the smog air pump which interferes with most single turbo kit installation.  The pulley kit under-drives both the alternator and water pump by 25%.

New: 3 Piece Pulley Kit: The pulley kit comes with alternator pulley, water pump pulley , main pulley, and two belts which eliminates the air pump but let you keep the A/C and Power Steering.  The pulley kit under-drives the alternator and water pump by 45%, power steering pump and A/C compressor by 25%.
