The Story
South Bend Clutch's 12 1/4 Dyna Max Kit is a single disc clutch and features an organic friction material comprised of 808 composite. This means reduced operating temperatures and ultra smooth engagement. This clutch is a good upgraded stock replacement for those who have stock to mild upgrades such as a programmer, can withstand up to 350hp and 700 lb. ft. torque, and is not recommended for extreme towing. Works on NV4500 and NV5600 non HO/ETH trucks.
