Fits: 2011 thru 2016 Chevy Silverado/GMC Sierra 2500HD/3500HD LML Duramax Diesel

SunCoast Performance replaces the factory flywheel/flexplate with an improved billet steel one-piece design which eliminates the heavy cast iron and the weak stamped steel flexplate. A must with high torque in conjunction with a better designed torque converter that can transfer the torque with no slip. With increased torque from the engine, it can crack and/or rip the center out of a stock flexplate.

Features:

• SFI 29.3 Certified
• Billet Steel one-piece design
• Eliminates weak & crack prone 3-piece OEM design

Notes:

• The stock bolts are torque to yield and one time use, so they will need to be replaced when replacing the flexplate, we would recommend replacing the flexplate bolts with OEM or DmaxStore Performance Flexplate bolts
• A SFI certified flywheel/flexplate is required on drag racing vehicles running 11.99 and quicker in the 1/4 mile and/or 7.49 and quicker in the 1/8 mile, or any vehicle exceeding 135 mph.
• To maintain the SFI specification 29.3 requirements, the flexplate must be replaced every three years for sanctioned racing applications
