JDC Titanium Cam Gear Hardware | Evo 8/9/DSM

Upgrade the cam gear hardware on your Mitsubishi Evo or DSM with JDC Titanium Cam Gear Hardware. Designed as direct replacements for the factory cam gear fasteners, these precision-machined titanium components replace ordinary OEM hardware with lightweight, corrosion-resistant titanium and the vibrant anodized finishes JDC is known for.

Choose from the Cam Gear Center Bolt, Cam Gear Timing Adjustment Hardware, or configure the hardware needed for your specific cam gear setup. These components are ideal for aftermarket adjustable cam gears, engine builds, restorations, and detail-focused engine bays where every piece of hardware matters.

Cam Gear Center Bolt

The JDC Titanium Cam Gear Center Bolt is designed as a direct replacement for the OEM Mitsubishi center bolt, part number MF140285. It maintains the required factory fitment while replacing the original hardware with premium titanium for improved corrosion resistance and a cleaner appearance.

  • Direct replacement for Mitsubishi part number MF140285
  • Precision-machined titanium construction
  • Sold individually
  • Evo 1 through Evo 8 and DSM applications require two center bolts when replacing hardware on both cam gears
  • Evo 9 MIVEC applications require only one center bolt

The Evo 9 MIVEC cam gear does not use the same center bolt. For a complete titanium appearance on Evo 9 applications, the JDC Titanium MIVEC Gear Cap can be purchased separately.

Cam Gear Timing Adjustment Hardware

JDC Titanium Cam Gear Adjustment Bolts replace the outer hardware used to secure the timing adjustment points on compatible adjustable cam gears. This hardware provides a clean finishing detail while allowing you to coordinate your cam gears with other JDC Titanium components throughout the engine bay.

  • Replacement hardware for cam gear timing adjustment points
  • Each adjustment kit includes titanium bolts and matching washers
  • Precision machined for a clean, premium appearance
  • Available in multiple JDC anodized titanium finishes

GR5 Titanium (Grade 5 Titanium) is a premium alloy composed primarily of titanium, with small amounts of aluminum (6%) and vanadium (4%) for added strength and versatility. Renowned for its exceptional strength-to-weight ratio, GR5 Titanium offers superior corrosion resistance, excellent heat tolerance, and remarkable durability. This makes it an ideal material for aerospace, automotive, medical, and high-performance applications, where lightweight strength and longevity are critical. Its ability to be anodized into vibrant colors further enhances its appeal for customization in industries like motorsports and jewelry.

How Do I Keep My Titanium Products Looking Brand New?

Installing: Wear gloves when installing titanium parts to prevent oils from your hands causing a "faded" look. After installation, clean the part before applying heat to avoid baking oils onto the surface.

Cleaning: Use our JDC Titanium Cleaner, designed to safely clean titanium without damaging the finish. Alternatively, clean with soapy water, a microfiber towel, or Windex, rubbing alcohol, or Clorox wipes.

Avoid: Harsh chemicals like water spot remover, engine degreaser, brake cleaner, metal polish, or acidic cleaners—they can damage the oxidized layer and remove the color.

Tip: Always clean when parts are cool to avoid water spots or tarnished finishes.
