What is the primary function of an idler pulley in a supercharger system?

An idler pulley's main job is to guide the supercharger belt and maintain the correct tension. This ensures the belt grips the pulleys effectively, allowing the supercharger to spin at the optimal speed and generate consistent boost.

What material is the HKS Idler Pulley D59 made from?

This idler pulley is constructed from a durable aluminum alloy. This material is chosen for its lightweight properties and its ability to handle the rotational forces and heat generated within a supercharger system.

Can this pulley be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

The HKS Idler Pulley D59 is constructed from a durable aluminum alloy, chosen for its lightweight properties and ability to withstand the rotational forces within a supercharger system. This pulley is designed as a direct replacement for the stock idler pulley, ensuring proper belt tension and alignment for optimal supercharger performance. Its well-built nature means it's made to handle the consistent stress of spinning at high RPMs, contributing to the overall reliability of your forced induction setup.

Properly functioning idler pulleys are crucial for maintaining the correct tension on your supercharger belt. If the stock pulley is worn or damaged, it can lead to belt slippage, reduced boost pressure, and premature belt wear. This HKS replacement part addresses those issues by providing a solid, reliable component that fits right into your existing supercharger drive system. It's a straightforward part to swap in when you're servicing your supercharger or noticing any issues with belt noise or tension.
