Heavy Duty Overrun Clutch Hub
Part No. 74574-HD

The overrun clutch hub found in GM 4L60 (700R4), 4L60E, 4L65E and 4L70E units is highly susceptible to cracking and breaking in applications such as autocross.

Stop hub failure in these popular performance units with Sonnax heavy duty overrun clutch hub 74574-HD, which features high strength steel and thicker material for trouble free performance when applying deceleration engine braking in D3, D2 or D1 ranges.

This hub is a direct replacement for ’95-later 4L60-E, 4L65-E, 4L70-E hubs and can be installed in a 4L60 (700-R4) when a 95-up sprag assembly is retrofitted.

  • 2X Thicker than OE clutch hubs to prevent cracking and breaking in critical areas that engage the input sprag inner race
  • Manufactured from high-strength 4140 chromoly steel
