Moroso Vacuum Pump Radius Tooth Pulley

Moroso Vacuum Pump Radius Tooth Pulleys are billet aluminum drive and driven pulleys for racing vacuum pumps, also called smog-style pumps. They are built to run efficiently and to take less power to turn the pump. This pulley line suits racing and performance engines that need steady vacuum for power brakes or for crankcase evacuation.

Key Features:

• Radius (round) tooth design with 8mm tooth technology, which helps the belt drive run efficiently
• CNC machined from billet aluminum
• Black anodized finish for durability and a clean look
• Made for 1/2" wide radius tooth belts
• Offered in a range of tooth counts, so you can choose the drive ratio you want and adjust the centerline distance between the pump and the crankshaft
• Pump pulleys use a 3-hole OEM-style mounting pattern, and drive pulleys fit standard 1.00" mandrels with a 1/8" keyway
• Made in the USA by Moroso

Pair a Moroso radius tooth drive pulley with a matching pump pulley and the correct radius tooth belt. This gives a complete, low-drag vacuum pump drive. Moroso has a long record in motorsports and builds these pulleys for hard use.
