74-78 Mustang II Main Hoop

The 74-78 Mustang II Main Hoop from Competition Engineering is a structural roll bar assembly designed for serious street and strip enthusiasts who demand maximum chassis rigidity and occupant protection. Built to fit first-generation Mustang II platforms from 1974 through 1978, this main hoop serves as the primary lateral bracing point in any modern suspension or engine swap upgrade.

Engineered by Competition Engineering using high-strength steel tubing, the 74-78 Mustang II Main Hoop mounts directly to the existing frame pickup points without requiring extensive drilling or modification. The hoop's geometry spans 47 inches wide and 56.25 inches tall, effectively distributing lateral and torsional loads across the chassis, which helps reduce body flex during hard cornering or acceleration.

Installation is accessible to experienced DIY builders with basic welding capability or professional shops equipped for chassis work. This assembly adds minimal curb weight at 23.8 lbs while providing measurable improvements in steering response and structural integrity, particularly when combined with modern suspension components or forced-induction engines.
