Subframe Connectors - 66-74 B-Body

The Competition Engineering Subframe Connectors for 66-74 B-Body Mopar vehicles are bolt-on structural reinforcement components engineered to reduce chassis flex and improve handling dynamics during spirited driving or performance use. Built from 2 x 1-1/2 x 0.083 inch steel tubing with a durable black powder coat finish, these subframe connectors bridge the gap between the front and rear subframes to create a more rigid platform that resists torsional stress.

The tubing dimensions—2 by 1-1/2 inches—provide substantial cross-sectional area for load distribution without requiring cutting or welding to the unibody. Bolt-on installation allows for straightforward fitment on original equipment subframe attachment points, making these connectors accessible to enthusiasts without specialized fabrication skills. The black powder coat protects against corrosion and provides a clean finish that integrates with factory undercarriage components. At 27 lbs, the complete kit adds minimal weight while delivering measurable reductions in chassis twist during cornering, acceleration, and braking events—conditions where unbraced B-Body frames can exhibit noticeable flex.

These connectors are purpose-built for owners of 1966–1974 B-Body Dodge and Plymouth vehicles (Charger, Coronet, Road Runner, Satellite, and related models) who are upgrading suspension geometry, improving handling response, or adding performance power plants. A more rigid chassis platform reduces the need for compensatory suspension tuning and provides more predictable vehicle behavior under demanding driving conditions. This is a complete two-piece kit ready to bolt directly to your B-Body frame.
