ARP Torque Converter Bolts - Prevent Catastrophic Transmission Failure

Secure your torque converter to the flexplate with ARP's precision-engineered torque converter bolts. Designed for high-stall converters, drag racing, and high-horsepower automatic transmissions, these bolts provide superior strength and reliability compared to stock hardware that can loosen, stretch, or shear under extreme loads.

Why Torque Converter Bolts Fail

Stock torque converter bolts are marginal even at factory power levels. Under high-RPM launches, aggressive stall speeds, or increased engine torque, stock bolts can stretch and loosen, allowing the converter to separate from the flexplate. The result is catastrophic—destroyed transmission cases, damaged bellhousings, and potential injury from flying debris. ARP torque converter bolts are heat-treated to 180,000 PSI tensile strength, ensuring your converter stays securely attached under the most demanding conditions.

ARP Torque Converter Bolt Features:

• 180,000 PSI Tensile Strength: Heat-treated 8740 chromoly steel for maximum strength and fatigue resistance
• Precision Thread Rolling: Threads are rolled after heat treatment for superior strength compared to cut threads
• 12-Point Head Design: Allows precise torque application and prevents rounding during installation
• Black Oxide Finish: Corrosion-resistant coating for long-lasting durability
• Complete Kits: Includes the correct quantity of bolts for your specific application
• Proper Length: Application-specific lengths ensure correct engagement without bottoming out

Common Applications:

• High-stall torque converters (2500+ RPM stall)
• Drag racing and bracket racing automatic transmissions
• Powerglide, TH350, TH400, 700R4, 4L60E, 4L80E transmissions
• LS engine swaps with automatic transmissions
• Street/strip performance builds
• Any high-horsepower automatic transmission application
• Transmission rebuilds requiring upgraded fasteners

Critical Installation Notes:

Torque Specifications: Always use ARP Ultra-Torque assembly lubricant and follow ARP's torque specifications. Typical torque is 25-30 ft-lbs, but verify for your specific application.

Thread Locker: Use medium-strength thread locker (blue Loctite) on torque converter bolts to prevent loosening from vibration.

Access: Torque converter bolts are accessed through the starter motor opening or inspection cover. Rotate the engine by hand to access each bolt.

Inspection: Always inspect torque converter bolts during transmission service. Replace if any signs of stretching, thread damage, or loosening are present.

Safety First: Never reuse stock torque converter bolts in performance applications. The small cost of ARP bolts is insignificant compared to the cost of transmission failure.
