Description

The B&M 20340 is a GM LSx SFI flexplate designed for LSx type motors, including models from 2010 and newer. It features a 14.13-inch outside diameter and a 168-tooth count. This flexplate is SFI 29.1 approved and legal for NHRA/IHRA classes.

Constructed with B&M's Radial Tension Technology, it offers a balance of extreme strength, flexibility, and minimal weight. The design allows for the removal of unnecessary material in non-critical stress areas, resulting in a lightweight yet strong component.
