Product Description

The TCI 399273 is a black steel automatic transmission flexplate for GM SBC, BBC and LS engines. It uses a 168 teeth ring gear, internally balanced construction, and SFI 29.1 approval for performance drivetrain use.

The heavy-duty construction is 0.035 in thicker than stock, and the starter ring is welded to both sides of the flexplate for added strength. High-tensile material helps resist elongation and cracking, while precision balancing and runout checks support smoother operation.

This flexplate uses large, small and LS bolt patterns and 10-1/2 in and 11-1/2 in torque converter bolt circle details where specified. It is listed with large, small and LS bolt patterns and a 2-piece rear main bearing attribute. TCI lists limited 30-day racing and 90-day street-strip warranty coverage.
