The PMR NHRA Chromoly 8.50 SFI Roll Cage Kit for the 1970 - 1976 Plymouth Duster is designed to be easier to install than every other kit on the market — starting with the details that matter most.

Designed Specifically for the Duster Engineered around real‑world chassis data for a tight, accurate fit that eliminates guesswork.
