The system uses a tubular K-member that reduces weight and clears big-tube headers, along with modular motor mounts that support many engine options including Gen III Hemi power. Tubular control arms and rack-and-pinion steering improve drivability and handling, and the kits bolt in without cutting or welding. Mustang II spindles are used for a wide range of brake options. QA1 systems are made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: front coil-over conversion suspension system\u003c\/li\u003e\n\u003cli\u003eShock valving: Double-Adjustable\u003c\/li\u003e\n\u003cli\u003eSpring rate: 350 lb\/in high-travel springs\u003c\/li\u003e\n\u003cli\u003eIncludes: tubular K-member, tubular upper and lower control arms, rack-and-pinion steering, coil-over shocks, springs, modular motor mounts, and hardware\u003c\/li\u003e\n\u003cli\u003eSpindles: Mustang II\u003c\/li\u003e\n\u003cli\u003eInstallation: bolt-in, no cutting or welding\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 52348-D350\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1966 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1966 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1966 Plymouth Belvedere\u003c\/li\u003e\n\u003cli\u003e1966 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1967 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1967 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1967 Plymouth Belvedere\u003c\/li\u003e\n\u003cli\u003e1967 Plymouth GTX\u003c\/li\u003e\n\u003cli\u003e1967 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1968 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1968 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1968 Plymouth Belvedere\u003c\/li\u003e\n\u003cli\u003e1968 Plymouth GTX\u003c\/li\u003e\n\u003cli\u003e1968 Plymouth Road Runner\u003c\/li\u003e\n\u003cli\u003e1968 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1969 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1969 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1969 Plymouth Belvedere\u003c\/li\u003e\n\u003cli\u003e1969 Plymouth GTX\u003c\/li\u003e\n\u003cli\u003e1969 Plymouth Road Runner\u003c\/li\u003e\n\u003cli\u003e1969 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1970 Dodge Challenger\u003c\/li\u003e\n\u003cli\u003e1970 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1970 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth Belvedere\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth GTX\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth Road Runner\u003c\/li\u003e\n\u003cli\u003e1970 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1971 Dodge Challenger\u003c\/li\u003e\n\u003cli\u003e1971 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1971 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth GTX\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth Road Runner\u003c\/li\u003e\n\u003cli\u003e1971 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1972 Dodge Challenger\u003c\/li\u003e\n\u003cli\u003e1972 Dodge Charger\u003c\/li\u003e\n\u003cli\u003e1972 Dodge Coronet\u003c\/li\u003e\n\u003cli\u003e1972 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1972 Plymouth Road Runner\u003c\/li\u003e\n\u003cli\u003e1972 Plymouth Satellite\u003c\/li\u003e\n\u003cli\u003e1973 Dodge Challenger\u003c\/li\u003e\n\u003cli\u003e1973 Plymouth Barracuda\u003c\/li\u003e\n\u003cli\u003e1974 Dodge Challenger\u003c\/li\u003e\n\u003cli\u003e1974 Plymouth Barracuda\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat does this QA1 Mopar front coil-over system replace?\u003c\/h5\u003e\u003cp\u003eIt replaces the factory torsion bar front suspension on classic Dodge and Plymouth B-Body and E-Body cars with a modern tubular K-member and coil-over setup.\u003c\/p\u003e\u003ch5\u003eDoes installation require cutting or welding?\u003c\/h5\u003e\u003cp\u003eNo. The system is engineered to bolt in without cutting or welding.\u003c\/p\u003e\u003ch5\u003eWhat spring rate and shock adjustment does part 52348-D350 use?\u003c\/h5\u003e\u003cp\u003ePart 52348-D350 is built with double-adjustable coil-over shocks and 350 lb\/in high-travel springs.\u003c\/p\u003e\u003ch5\u003eWill this system work with a Gen III Hemi?\u003c\/h5\u003e\u003cp\u003eYes.
