Like other owners of Mopar A-Bodies (19641974 Plymouth Duster/Valiant/Barracuda and Dodge Dart/Demon), Chris discovered he needed more room for the six-speed Tremec T56 transmission he was eyeing, and the Chrysler torsion-bar crossmember just doesn't allow any room for it. It seems there's a lot to recommend the torsion-bar suspension, so why change it? (Love your Mopar's torsion-bar suspension setup? See a rehab and upgrade here.) The truth is, you may not want to change it-unless you do. it certainly dont go together as easy as the video shows. Comparable coil-spring suspensions from competitors were not only heavier but also moved the mass out nearer to the corners, costing them a measure of handling capability. great suspension kit.just installed this in my 68 barracuda looks and works great. Its proximity to the boxed c-channels, the cockpit, and cowl area meant very little chassis flex, a superior ride, and better-than-average handling for its day. In the absence of a full frame, the torsion-bar crossmember provided the bulwark for a significant amount of the chassis' stiffness while also supporting nearly all the load of the front half of the car. Unseen and largely forgotten, few parts of any car up to this point had taken on so many important roles. Most critical to the success of the Chrysler chassis design was the torsion bar's supporting crossmember. Chrysler's move to a torsion-bar suspension wasn't new, but integrating it so thoroughly into the unibody's new construction was. Then, just as today, that meant finding new and creative ways to package the mechanical systems. in the early 1960s, many of Detroit's automakers redesigned their car platforms and powertrains for less mass and greater fuel efficiency. Altogether, more than half a million A-bodies were sold in the United States alone, a number even the. (Learn the history of the Mopar A-Body here.) The fact that it was so good, ironically, is the problem, and needs explanation before we get into why we're replacing it in this 1974 Plymouth Duster, a project vehicle owned by HOT ROD tech center mechanic Chris Arriero.Īs an economic recession hit the U.S. The 1972 Dart, Demon, and Swinger together sold more than 200,000 units, a phenomenal performance by modern American-car standards, but they were actually outsold by a good margin by their Plymouth equivalents, with well over 300,000 sales. The torsion-bar suspension found on vintage Chrysler cars from the '60s and '70s is perhaps the poster child for this, as arguably no manufacturer of the era had a more capable independent front suspension (IFS) design. Yukon Master Overhaul Kits are the most complete kits on the market and include all differential bearings and races along with seals, shims and high quality small parts.From a hot rodder's perspective, it's never an easy decision to completely replace a vintage car's front suspension with something newer that is of a completely different design.
