ARP GM 200/700 4L60/4L80 Torque Converter Bolt Kit - Chevrolet Big Block, 6 Piece

ARP torque converter bolt kit for GM 200, 700, 4L60 and 4L80 automatic transmissions, supplied as a 6-piece kit. Torque converter bolts see reversing load every time the converter loads and unloads; ARP fasteners are cold-formed and thread-rolled after heat treat so the thread root is left in compression, which is where a stretched converter bolt normally starts to fail.

This is the Chevrolet big block kit in the pair. ARP lists 230-7305 for Chevrolet big block engines only, whereas the companion kit 230-7304 is listed for Buick plus Chevrolet small block and big block. The two share an identical kit name in ARP's catalog, so order by part number.
