Long Tube.
These uncoated, LONG-TUBE headers fit 1980-95 2WD Ford 1/2, 3/4 and 1 ton, and 1982-96 4WD Ford 1/2, 3/4 and 1 ton Trucks and Broncos with a 351W (5.8L) non-E.G.R. engine. The long, smooth-flowing 1-1/2 in. tube design provides superb exhaust flow to let your Ford truck's 5.8L engine breathe easy, and produce loads of horsepower and torque. They fit column-shift automatic and floor-shift manual transmissions, but will not work on lifted trucks, or 4WD models with a Dana 60 front differential.
These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures.
Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.
Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
