1975-1980 Dodge D100 - Gen III Hemi Swap

In 1972, the D100 received a complete redesign that lasted until 1980. With it came an independent front suspension and more rounded styling cues borrowed from contemporary Mopar cars. An extended cab was optional for the first time ever on any pickup and one of the most iconic Dodge vehicles of all time saw the light of day; The Li'l Red Express. But, if your D100 is struggling to keep up with the times, our Gen III Hemi Swap kits are just what you need.
