Secure Your Aftermarket Converter

If you have upgraded your GM Turbo 350 or Turbo 400 transmission with an aftermarket torque converter, you need hardware that can handle the increased performance. The ARP 230-7302 Torque Converter Bolt Kit is specifically designed to secure aftermarket converters, providing the strength and reliability that stock bolts simply cannot match.

Why Upgrade Your Converter Bolts?

  • Engineered for Performance: Specifically designed to accommodate the unique mounting requirements of aftermarket torque converters.
  • High-Strength Alloy: Manufactured from premium materials to prevent bolt stretch and ensure a secure connection under high torque.
  • Precision Threads: Rolled threads ensure accurate torque application and maximum holding power.
  • Durability: Finished with a protective coating to resist corrosion and wear in harsh under-car environments.

Aftermarket converters often have different mounting hole specifications or require specific fastener profiles. Using the wrong hardware can lead to loose converters, vibration, and catastrophic transmission damage. These ARP bolts are the professional choice for ensuring your converter stays perfectly aligned and secure. Don't compromise your transmission build with inferior hardware. Get the best in the industry for your performance vehicle at GGCRACING.
