Show original supplier description
The Circle D Specialties FLEX-BS-GM-LST-8 is a high-strength billet steel flexplate designed for LS, LSA, and Gen-V LT applications. Engineered in-house using Finite Element Analysis, this flexplate is crafted for optimal strength and minimal weight, making it suitable for racing, daily driving, or towing. It boasts SFI 29.2 certification, the highest possible rating, ensuring its safety and durability. Constructed from a single piece of billet steel, this flexplate features an attractive black finish and 168 teeth. It is compatible with both 6-bolt and 8-bolt crankshafts and includes universal GM torque converter bolt patterns with multiple bolt circle options (6 x 10.75-inches, 6 x 11.06-inches, & 6 x 11.50-inches). A pilot adapter may be required for certain torque converters with standard short GM pilots to ensure proper engagement with the crankshaft pilot. Torque converters with LS/Gen-V LT-length pilots will not need this adapter. This flexplate is street-legal for all 50 states, as indicated by its EMS Code 4, meaning it does not require an EO in California.
