The Sun Coast A1-BFP-4 Allison Billet Flexplate replaces the factory flex plate on your Duramax, featuring an improved billet steel one-piece design that eliminates the weak stamped steel flex plate. Stock flex plates can crack under the pressure of higher power output applications. Combined with a SunCoast torque converter, this durable flex plate can easily transfer the higher torque output with no slipping. The flex plate is bolted to the crankshaft, then the converter is bolted to the flex plate. The torque from the engine is transferred to the flex plate, then to the torque converter, and finally to the input shaft in the transmission.

FEATURES:

• Billet flex plate
• Enhanced durability

Note:

• An SFI certified flywheel flex plate is required on drag racing vehicles running 11.99 seconds or quicker in the 1/4 mile and 7.49 seconds or quicker in the 1/8 mile, or any vehicle exceeding 135 mph. It was changed in 2008 from the 29.1 SFI specification to the SFI specification 29.3 for automatic transmission flex plates for diesel applications. The new rules for the flex plate require that the material cannot be stamped metal as are many OEM and aftermarket flex plates. To maintain the SFI specification 29.3 requirements, the flex plate must be replaced every three years.

Upgrade your Duramax with the Sun Coast A1-BFP-4 Allison Billet Flexplate for enhanced durability and performance, ensuring reliable power transfer under demanding conditions.
