Hooker Blackheart Gen III Hemi swap headers are one part of a fully engineered swap system that provides maximum component clearances, ideal drive train geometry & clearance for a 3.00" exhaust system. The swap system fits the 1972-1993 Dodge D100/D150 2WD trucks & includes Headers BH2355 or BH2366, Motor Mounts BHS524, Crossmember BHS525, exhaust systems (BH2356, BH2357, BH2467, or BH2468), and the appropriate adapter for your choice of transmission (each part number is sold separately). These high-quality mid-length swap headers are made from 304 stainless steel and feature 3/8" thick header flanges, 18-gauge 1-7/8" primary tubes, and 3.00" collectors (w/ merge spears). Headers provide clearance to the brake booster, steering shaft, power steering box, starter (both left & right side-mounted), OE (original equipment) rear sump oil pan, and provide clearance for several automatic & manual transmission options.
