ARP GM 200/700 4L60/4L80 Torque Converter Bolt Kit - Buick and Chevrolet Small & Big Block

ARP torque converter bolt kit for GM 200, 700, 4L60 and 4L80 automatic transmissions. Torque converter bolts are a common failure point on a built engine: the factory bolts stretch, back out and let the converter walk away from the flexplate. ARP fasteners are cold-formed and thread-rolled after heat treat, which puts the thread root in compression and raises fatigue life over a cut-thread bolt.

This is the wide-application kit in the pair. ARP lists 230-7304 for Buick and both Chevrolet small block and big block engines, while the companion kit 230-7305 is listed for Chevrolet big block only. Check the application list below against your combination before ordering, and match the part number rather than the kit name - ARP publishes the same kit title for both numbers.
