Engineered for racers who demand precision, safety, and a true competitive edge.

The PMR NHRA Chromoly 6pt Roll Cage 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. 

Why PMR Leads the Industry

• CNC Precision‑Notched Tubing Every tube in this kit is Notched in-house for exact fitment. Competitor kits often arrive without any notched ends — leaving you to fight gaps, angles, and wasted time. PMR’s precision notching means faster assembly, cleaner welds, and a cage that fits the first time.
• Chromoly Superiority: Stronger than mild steel while using thinner wall tubing, resulting in a lighter, higher‑strength cage that improves ETs, chassis response, and structural integrity.
• Designed Specifically for the Plymouth Duster Engineered around real‑world chassis data for a tight, accurate fit that eliminates guesswork.
• All Base Plates are Precision cut and bent, ready to be welded.
• Instructions Included for easier assembly.

It is the customer’s responsibility to ensure the cage is installed correctly and meets all certification requirements for their racing sanctioning body.
