Torsion-bar front suspensions are very durable and offer easy adjustment of ride height, regardless of age. Torsion bar front suspension systems as used in all Chrysler, Plymouth, and Dodge vehicles (beginning in 1957 and lasting through 1979), are perhaps the easiest suspension systems to modify that were available as original equipment. The lever in the lower suspension arm has an adjuster that can apply more or less pressure (preload) on the torsion bar. The front mount of the torsion bar is a six-sided socket built into a lever and attached inside the lower suspension arm, also perpendicular to the torsion bar. The rear mount of the torsion bar is inserted into a six-sided socket built into the floorpan crossmember, which is perpendicular to the torsion bar. The torsion bars run from the floorpan crossmember to the front lower suspension arms. The torsion-bar system from a 1972 Dodge Demon consists of two round steel bars (one left and one right) with a 1¼-inch hex on both ends measuring 35.7 inches long. He may have left a little early (note the red light) but he left strong! This 1972 Dodge Demon belongs to Caffey Broadus and was seen at the National Muscle Car Association (NMCA) Finals in Memphis, Tennessee, in 2009.Ĭhrysler B-Body cars with 41-inch-long torsion bars include:Ĭhrysler E-Body cars with 41-inch long torsion bars include: Therefore any bar with the same length could be swapped into another car regardless of diameter.Ĭhrysler A-Body cars with 35.7-inch-long torsion bars include: For all three bodies, the hex end measured 1¼ inches. The A-Body torsion bars were 35.7 inches long, while the B- and E-Body bars were 41 inches long. You can copy and paste this link to share: Ĭhrysler had three main passenger car platforms called A, B, and E.

Although all of these torsion-bar systems operate basically in the same manner, this book concentrates on the Chrysler-built cars as they are still popular on most drag strips around the country. They are currently used in trucks and SUVs from Ford, General Motors, and Dodge. Torsion-bar suspension systems were used in most Chrysler vehicles of the 1950s, 1960s, and 1970s, Cadillac Eldorado, Oldsmobile Toronado, Packard, and more. A torsion bar is a long round spring steel bar that resists twisting and returns to its original position after being twisted, thus providing a spring action for the car.
