BILLET SFI APPROVED FLEXPLATE
The Sun Coast 618-BFP Billet Flex Plate for your 1994-2007 Dodge
5.9L Cummins is a must have when it comes to putting power to
the ground in your truck. The high torque of your Cummins in
conjunction with a better designed torque converter can transfer
the torque with no slip. The flex plate is bolted to the crank
shaft, then the converter is bolted to flex plate. The torque
from your Cummins is transferred to the flex plate, from the
flex plate to the torque converter then to your input shaft
in the trans. With increased torque from the engine and no slip
out of the converter it can crack and/or rip the center out
of a stock flex plate.
Sun Coast billet flywheels are CNC machined from a forging
for strength and reliefs are machined out between the converter
mounting area and the crank flange to enable some flex. We
designed our flexible billet flywheel with the understanding
that it needs to flex but at the same time we added extra
thickness to prevent cracking. We started with a better quality
material and a better manufacturing process to make it stronger.
Our flexible flywheel made or exceeded all the SFI specification
29.3 requirements for materials, mechanical properties, design
and rotational integrity.
Factory Flex Plate
29.3 SFI Specifications
A SFI certified flywheel flex plate is required on drag
racing vehicles running 11.99 and quicker in the 1/4 mile
and 7.49 and quicker in the 1/8 mile, or any vehicle exceeding
135mph. 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
flexplate requires that the material can not be a stamped
metal as many OEM and aftermarket flex plates are. To maintain
the SFI specification 29.3 requirements, the flex plate
must be replaced every three years.
Suncoast orders require the year, make, and model of your
