Mopar Torque Converter Bolt Kit

The Mopar Torque Converter Bolt Kit (MPN 240-7301) is an essential fastening solution for serious transmission rebuilders and performance enthusiasts working on Mopar-equipped vehicles. This kit addresses one of the most critical stress points in any automatic transmission assembly—the connection between the torque converter and flexplate. Whether you're performing a stock rebuild or upgrading to a high-stall converter for improved launch characteristics, using OEM-grade fasteners ensures proper clamping force, eliminates vibration, and prevents catastrophic converter separation during hard acceleration.

Torque converter bolts experience extreme shear and tensile loads, especially during aggressive driving or forced induction applications where engine torque multiplication occurs. This kit is engineered to exact Mopar specifications, ensuring proper thread pitch, bolt grade, and coating to resist corrosion and galling during installation and thermal cycling. The precision-manufactured fasteners maintain consistent clamp load across the converter mounting interface, critical for preventing leaks at the front seal and avoiding premature converter failure. Professional mechanics rely on spec-matched bolt kits because substandard fasteners can slip under load, leading to transmission fluid loss and catastrophic internal damage.

This kit is ideal for transmission rebuilders, drag racing enthusiasts, and daily-driver owners performing DIY or professional transmission service on Mopar automatic gearboxes. Compatibility spans multiple Mopar transmission platforms where this specific bolt pattern and fastener specification applies. When installing, proper torque sequence and values are essential—cross-tighten in a star pattern to ensure even pressure distribution across the converter mounting face. Always replace bolts during any transmission service or converter replacement to guarantee reliable operation and eliminate the risk of converter slip or separation.
