ATS Allison Billet Flex Plate for Chevy/GMC (2001-19) 6.6L Duramax

The ATS Allison Billet Flex Plate for 2001-2008 GM 6.6L Duramax is an ATS Diesel Performance upgrade for trucks that see added power, heat, or heavy towing. ATS designs its parts around the failures it sees in its own transmission and engine work, so each upgrade targets a known weak point.

The flexplate connects the crankshaft to the torque converter, so every bit of engine torque passes through it on the way to the transmission. Factory flexplates are stamped steel, and on a truck with added power and hard launches they can crack around the bolt holes or at the center hub.

ATS Diesel Performance has built diesel transmissions and performance parts since 1993. ATS designs, engineers, and manufactures most of its products in-house at its Arvada, Colorado facility, and tests them at altitude on the same long grades its customers tow on.
