Moroso 23535 Vacuum Pump Radius Tooth Pulley

The Moroso 23535 is a precision-engineered radius tooth pulley designed to drive vacuum pumps more efficiently while reducing parasitic power loss. This pulley features a radius tooth profile that provides superior belt engagement compared to traditional V-belt designs, resulting in smoother operation and improved power transfer.

Key Features:

• Radius tooth design for efficient power transfer and reduced drive load
• 0.500-inch wide belt compatibility
• Fits standard 1-inch mandrel with 1/8-inch keyway slot
• Precision-machined aluminum construction for strength and light weight
• Black anodized finish provides corrosion resistance and professional appearance
• Compatible with various drive pulley sizes for custom ratio configurations

This pulley is ideal for racing and high-performance applications where vacuum pump efficiency is critical. The aluminum construction keeps rotating mass low while the anodized finish ensures long-lasting durability in demanding engine bay environments. Works with external vacuum pump systems to enhance ring seal and reduce crankcase pressure.
