The setup provides a more planted feel, room for larger wheels and tires, wheelbase correction, and clearance for a 3 inch bumper-exit exhaust. Powder-coated tubular components, including the crossmember and upper and lower trailing arms, come with all required hardware. The system works with popular rear axles including the Mopar 8-3\/4 inch, Ford 9 inch, and Dana 60. Single-adjustable coil-over shocks allow ride and handling to be fine-tuned and the ride height to be adjusted.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: triangulated four-link rear coil-over suspension system\u003c\/li\u003e\n\u003cli\u003eShock valving: Single-Adjustable\u003c\/li\u003e\n\u003cli\u003eRear axle compatibility: Mopar 8-3\/4 inch (also offered for Ford 9 inch and Dana 60 under other part numbers)\u003c\/li\u003e\n\u003cli\u003eExhaust clearance: fits 3 inch bumper-exit exhaust\u003c\/li\u003e\n\u003cli\u003eFinish: powder coated\u003c\/li\u003e\n\u003cli\u003eIncludes: tubular crossmember, upper and lower trailing arms, coil-over shocks, springs, and hardware\u003c\/li\u003e\n\u003cli\u003ePart number: R150-175\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1963 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1963 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1964 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1964 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1964 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1965 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1965 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1965 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1966 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1966 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1966 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1967 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1967 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1967 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1968 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1968 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1968 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1969 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1969 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1969 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1970 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1971 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth Scamp\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1972 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1972 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1972 Plymouth Scamp\u003c\/li\u003e\n\u003cli\u003e1972 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1973 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1973 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1973 Plymouth Scamp\u003c\/li\u003e\n\u003cli\u003e1973 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1974 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1974 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1974 Plymouth Scamp\u003c\/li\u003e\n\u003cli\u003e1974 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1975 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1975 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1975 Plymouth Scamp\u003c\/li\u003e\n\u003cli\u003e1975 Plymouth Valiant\u003c\/li\u003e\n\u003cli\u003e1976 Dodge Dart\u003c\/li\u003e\n\u003cli\u003e1976 Plymouth Duster\u003c\/li\u003e\n\u003cli\u003e1976 Plymouth Scamp\u003c\/li\u003e\n\u003cli\u003e1976 Plymouth Valiant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhich cars does the QA1 R150-175 rear system fit?\u003c\/h5\u003e\u003cp\u003eIt fits classic Mopar A-Body cars, 1963-1976 per the fitment table.\u003c\/p\u003e\u003ch5\u003eWhat does this system replace?\u003c\/h5\u003e\u003cp\u003eIt replaces the factory leaf-spring rear suspension with a triangulated four-link coil-over design.\u003c\/p\u003e\u003ch5\u003eWhich rear axles does it work with?\u003c\/h5\u003e\u003cp\u003eQA1 Mopar rear systems work with popular rear axles including the Mopar 8-3\/4 inch, Ford 9 inch, and Dana 60; this part number is configured for the 8-3\/4 inch axle.\u003c\/p\u003e\u003ch5\u003eDoes it clear a bumper-exit exhaust?\u003c\/h5\u003e\u003cp\u003eYes.
