Sway Bar - Front 1-1/4in 66-72 Mopar B-Body

The QA1 Sway Bar – Front 1-1/4in 66-72 Mopar B-Body (SKU QA152860) is a bolt-on front sway bar engineered for serious suspension tuning on classic Mopar muscle cars. Constructed from chromoly steel and finished in black powder coat, this 1.25-inch diameter bar delivers measurable improvements to cornering stability and body roll control—critical upgrades for owners restoring or restomodding first-generation B-Body platforms from 1966 to 1972.

The 1.25-inch diameter provides a balanced rate increase relative to original equipment, suitable for street-driven restorations and vintage autocross applications. Chromoly construction offers fatigue resistance superior to standard mild steel, allowing the bar to handle repeated load cycles without degradation. The black powder coat protects against corrosion while maintaining a clean, period-correct appearance under the vehicle. This component is designed specifically for QA1 K-Member installations, ensuring proper geometry and bushing clearance without modification. Weighing 13.7 pounds, it integrates seamlessly into front-end assemblies without requiring frame reinforcement on factory structures.

This sway bar appeals to Mopar B-Body and E-Body enthusiasts (1970–74 E-Body compatibility confirmed) undertaking suspension modernization. Drivers transitioning from soft factory settings to active handling demand reduced understeer and improved weight transfer during spirited driving. The upgrade is particularly valuable for vehicles receiving independent front suspension conversions, where factory anti-roll geometry may no longer be adequate. Installation requires basic hand tools and fits within the QA1 K-Member ecosystem, making it suitable for DIY builders and professional shops alike.
