American Racing Solutions 90mm 12 Rib Smooth Billet Idler Pulley Double Bearing (ARS9012DB)
Engineered for extreme horsepower applications, the American Racing Solutions 90mm 12 Rib Smooth Billet Idler Pulley with double bearing design delivers maximum strength, stability, and performance. Designed for high-load belt systems, this pulley is ideal for racers pushing the limits of their setup.
Machined from premium 6061-T6 billet aluminum and finished with a clear anodized coating, this pulley offers superior durability and a hardened surface to resist wear. The large 90mm diameter combined with a 12 rib configuration ensures optimal belt contact and stability, while the smooth surface design reduces friction in specific routing applications. For ultimate performance, optional ceramic hybrid bearings provide increased speed capability and efficiency.
Performance and Construction
This 90mm smooth idler pulley is built for strength and reliability under extreme conditions. The billet aluminum construction provides excellent durability while keeping weight low, and the clear anodized finish enhances surface hardness and corrosion resistance.
Double Bearing Design
The dual bearing configuration increases load capacity and improves stability, making it ideal for high-tension belt systems. This design helps maintain proper alignment and reduces deflection at high RPM and boost levels.
