Coils take up less room, allow one to lower the car (to drop the center of gravity), and allow moving the rear wheels farther to the rear. if (jsonResponse.status == true) { date.setTime(date.getTime()+(days*24*60*60*1000)); Unsprung weight is a disadvantage, and with the leaf springs, the axle is unsprung. return ((target) ? Still, torsion bars continued in two unexpected places. // if EU and execute eu tags * Follow factory torque sequence, Alternator Bracket to Block The torsion bar front springs used a high proportion of chromium in their steel (though they have been known to snap). //Execute Eu Tags Function JavaScript is disabled. } When the front wheel rose over a bump, the lower control arm pivoted around the points where the torsion bar was mounted, twisting the bar. Diagonally mounted steel struts reinforced and positioned the front-wheel lower control arms. Oh boy, could they ever. The suspension was sold for some years under the trademark Torsion-Aire. ordered the daystar level and did not come in the instructions. The four wheel drive Dodge Dakota also used torsion bars into the 1990s, and the cornering was excellent. I have seen a few threads but need to clarify so I don’t mess up. * Torque values shown are in Bolt, Water Pump Housing to Block } if (!geoIPCountryCode) if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); The angled upper control arms resisted brake dive; and in newer versions of the torsion-bar suspension (used in the 1970s and later) the upper control arm had a front pivot higher than its rear pivot instead of at equal height so that weight would shift forward when the brakes were applied, counteracting the extra weight caused by braking and helping to keep the car level. Widely spaced upper and lower ball joints provided a wide base of support for the front wheels to improve stability and reduce undesirable wheel motion. Damper), Torque Converter to Flexplate } if (! The Eagle Premier had the usual front-drive MacPherson strut front suspension, but instead of a solid beam rear axle in back, it used an independent torsion bar rear suspension. var nameEQ = name + "="; Getting ready to purchase the Mopar lift and install myself. Torsion-Aire used two chrome steel bars mounted parallel to the inner-front frame rails, the front portion of the bar mounted to the lower control arm with the opposite end anchored to the frame.

Along with its 950 lb.-ft. of torque, the complete engine assembly includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors and coil packs. Called “Torsion-Aire Ride” (there was no air to the system at all, unlike GM’s experiments with air suspensions), the suspension would garner Plymouth the title of best-handling car by Motor Trend magazine. function vsCFVerifyUserGeoIp(geoIps) { xhttp.open("GET", "/videoplayer/verify_user_eu_geoip.php?verifyUserGeoIp=true"); The long, flexible portions behind the axle benefited the ride. var ca = document.cookie.split(";"); } function vsCFSendAjax() { true : false) : (geoIps.includes(geoIPCountryCode) ? Rick Ehrenberg also suggested a complete suspension check to make sure all components were in good shape, then adjusting the steering box to be as tight as possible; and aligning the front end. to prevent broken bolts due to excessive torquing. Rubber bushings eliminated the need for lubrication in many spots, reduced friction, and absorbed road shocks. The system worked better than GM and Ford suspensions of the time, but eventually newer designs and the better materials to support them were developed. 3 bolts on top of the tower and the two bolts on the brace torque … return ((target) ? target = false; // Exclusion is selected * Follow factory torque sequence, RB/B Engine Torque Specifications Big Block Chrysler 383, 400, 440 Widely spaced, off-center mounted rear springs cut acceleration squat and also resisted brake dive. var vsCFTagsEUFunctions = vsCFTagsEUFunctions || []; The torsion-bar front suspension debuted in 1957 across the corporation’s models, and were used on all Chrysler Corporation cars until the front wheel drive cars arrived. In addition to the torsion bars, the company used an anti-sway bar (often just called “sway bar”) to resist lean in turns, with various degrees of success depending on its thickness and the suspension tuning; generally, Chrysler Corp products had less body roll than equivalent GM or Ford cars. Originally devised by Bob Batchelor, Chrysler’s torsion bar suspensions were used across the entire lineup, from Plaza and Valiant to Imperial, for decades. A full description of how to set alignment without a shop was in the October 2009 Mopar Action. } Chrysler Torsion Bar Car Suspensions, 1957-1992: Torsion-Aire, Torsion-Quiet. Torsion-Aire was more than just torsion bars; everything had been re-engineered, including the frame, wheels, tires, suspension, and steering linkage. vsCFExecuteNonEuTags(); return null; One advantage of the system used by Mopar tuners through the years has been the ability to easily raise or lower the front end of the car by adjusting the torsion bars; with coil springs, the springs must be replaced.

They only seemed to break at rest, not while on the road. “The same engineer (Bob Batchelor) responsible for the M-body design (transverse bars) corrected the problems on the [Eagle] Premier, in that the bars were “folded” together into a single, more compact design that was more rigid in bending and smoother riding, due to lower rate and greater travel.”. // if Non EU and execute Non eu tags Diagonally mounted steel struts reinforced and positioned the front-wheel lower control arms.
