TCI 399753 Flexplate, 153-Tooth, Internal Balance, 1-Piece Rear Main Seal, SFI 29.1, Chevy, 4.8/5.3/5.7/6.0L

• Thicker and stronger than factory flexplates
• Can be used with both LS and early transmissions and converters, thanks to dual converter bolt patterns
• SFY 29.1 is fully approved for racing purposes

GM LS1 engines are powerful machines. Make sure that that your faceplate can stand up to the RPMs they can create. The new TCI®
LS1 style flexplates are 67% thicker than the factory version, ensuring many years of flawless and reliable performance.

The ring gear is crafted precisely to make a perfect I.D. circle prior to welding the plate in place on both sides. This makes for a stronger, cleaner fit that prevents runout, ring gear bounce and other dangers seen when using inferior faceplates.

Dynamic balancing and electro-coating protect the flexplate from dangerous vibration as well as damage from the elements. It features an integrated early style dual converter bolt pattern, ideal for use with both LS and classic torque converters. It also works great with TH350/400, Powerglide, 700R4, 2004R and 4L60E/65E/70E transmissions.

These flexplates, which are fully SFT 29.1 approved, are the right choice for performance driving of all kinds, due to their outstanding strength and ability to shrug off RPM strains that would cause cracking and ring gear breakage in lesser plates.
