PHR JZ Titanium Serpentine Belt Idler Pulley Hardware 1JZ 2JZ

The PHR Titanium Serpentine Belt Idler Pulley Bolt and Nut is a simple upgrade with a big visual payoff. Designed primarily as an engine bay dress-up component, this titanium fastener replaces the factory steel hardware used on the serpentine belt idler pulley or tensioner arm.

Machined from high-grade titanium and offered in multiple finish options, this bolt allows you to fine-tune the look of the front accessory drive—whether you’re matching other titanium hardware or adding a subtle accent to an otherwise clean setup. While titanium offers excellent corrosion resistance and strength, the real benefit here is a refined, intentional appearance that elevates the entire engine bay.

Features

• Available in multiple finishes to match or accent your engine bay
• Premium titanium construction
• Direct replacement for factory idler pulley / tensioner hardware
• Designed for Toyota & Lexus 2JZ / 1JZ engines
• Ideal for detail-focused builds, show cars, and clean street setups
• A small detail—but one that stands out when everything else is done right.

Manual or Automatic Tensioner:
How to spot the difference! Be careful when selecting your bolt style. It is often the case that someone could have done an engine swap or tensioner arm swap if you weren't the first owner of your car. Verify the tensioner arm in your car. Just because you have a manual or automatic transmission doesn't mean that is the tensioner arm you have on your engine. These are the arms as they come equipped on manual or automatic transmission equipped cars.
