Performance builders, this March Performance power steering pulley is serious upgrade material! CNC machined from 6061-T6 aluminum, this 6-rib pulley runs perfectly true and delivers that clean billet look. The clear powder coat finish means no polishing ever - it stays looking new through years of use. With a 6-3/8-inch outside diameter and 3/4-inch bore, it uses press-fit mounting for secure installation. But here's the performance benefit: this pulley reduces accessory drag by 12-15 horsepower at the rear wheels! That's free power you're currently wasting on turning your power steering pump. The quality is exactly what you'd expect from March Performance - precision machining, perfect balance, and durability that handles high-RPM operation. Whether you're building a street machine, race car, or just want better efficiency from your engine, this pulley delivers both style and substance. Backed by a 90-day warranty, it's a smart upgrade that pays dividends in both looks and performance.
