Standard Uncoated Hedders; 1-3/4" Tube Dia.; 3" Coll.; SHORTY Design These uncoated, MID-LENGTH TUBE, headers fit 1988-92 2WD and 1988-97 4WD F150, F250 and F350 trucks (light-duty only) with a 7.5L (460 CID) EFI powerplant. The long, smooth-flowing 1-3/4 in. tube design provides great exhaust flow to let your F-Series truck's 7.5L engine breathe easy, and produce amazing amounts of torque. They fit column-shift, automatic transmission vehicles only, and are not designed for use on Super-Duty F-series trucks. These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish. Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.
