ATS Allison C4 Clutch Pack for Chevy/GMC (2001-10) 2500/3500 6.6L Duramax

The ATS Allison C4 Clutch Pack for 2001-2008 GM 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.

Clutch packs are what actually hold each gear. More friction surface, or better friction material, lets the transmission hold more torque without slipping, which is what keeps it alive behind a modified diesel.

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.
