Billet Pulleys

All ARS billet pulleys are CNC-machined from 6061-T6 billet aluminum and anodized for a hardened, corrosion-resistant finish that holds up to the abuse of high-RPM and boosted applications.

Built for serious racers and performance enthusiasts, our pulleys are available in smooth or grooved designs with single or double bearing options. Step up to ceramic hybrid bearings for lower friction, higher RPM capability, and longer life under extreme conditions.

**Why ARS Billet Pulleys Win Races:**
- Significantly lighter than steel with superior corrosion resistance
- Maximum strength and durability for high-horsepower builds
- Available in 8, 10, and 12 rib configurations
- Proven on Coyote, Mustang, Hellcat, GT500, HEMI and other modern muscle cars

Every thousandth of a second counts on the track. Our ceramic bearing upgrade uses lighter, harder ceramic balls that reduce friction and heat, letting you spin faster and put more power to the ground.
