Category: Late MOPAR "B" Body High-Performance Torsion Bars (43.50” Mid-Era Architecture) 

​Engineered by Sway-A-Way, these 43.50” high-performance longitudinal torsion bars are designed specifically for late-period MOPAR "B" body platforms (Dodge, Chrysler, and Plymouth). By the mid-to-late 1970s, factory MOPAR setups shifted drastically toward an overly soft, isolated luxury ride, causing massive body roll through corners, heavy nose-dive under braking, and structural wallowing. This solid alloy steel set delivers a calculated increase in spring rate, sharpening steering response, stabilizing the front track geometry, and eliminating float without harshness—perfect for modernizing the road manners of these classic personal luxury coupes and late muscle cruisers.
​Performance & Fitment
    • Application: Late MOPAR "B" Body vehicles, including:

      • Dodge Charger, Coronet, Monaco

      • Chrysler Cordoba

      • Plymouth Fury, Road Runner

    • Years: 1975–1981 (Mid-to-late platform architectures using the extended receiver layout).

    • Length: 43.50" (Exact factory longitudinal length specification for late-period "B" bodies; note: product data contains a minor cataloging label mismatch—these do not fit early 35.80" "A" bodies).

    • Hex Clocking: The hex heads on each end are precisely engineered and indexed ("clocked") relative to one another based on the specific spring rate. This guarantees your adjustment bolts remain perfectly centered within their operational sweep at target ride height.


​Premium Construction

    • Material: Solid Alloy Steel. Forged from premium racing-grade steel designed to handle massive structural twisting loads without sagging, flattening out, or losing its memory over time.

    • Manufacturing Process: Centerless Ground & Heat-Treated. Through-hardened to achieve an optimal balance of tensile strength and elasticity. The centerless grinding process strips away surface imperfections, producing a perfectly uniform diameter and eliminating potential "stress risers" where micro-fractures typically start.

    • Coating: Heavy-Duty Powder Coating. Provides a robust barrier against road moisture, grime, salt, and engine fluids, ensuring long-term protection against corrosive pitting.

  • 🇺🇸 MOPAR Muscle Suspension Tech & Installation Notes

    Upgrading to a 43.50" high-performance torsion bar system on a mid-era Chrysler platform requires strict adherence to factory procedures to ensure a safe installation and proper chassis leveling:

  • ⚠️ Caution: High-Tension Energy: Torsion bars operate under immense mechanical tension, which is amplified by heavy small-block and big-block V8 engines. Before attempting to loosen or remove the bars, you must raise the vehicle and support the frame securely with jack stands so the front suspension hangs completely free. Back out the torsion bar adjusting bolts in the lower control arms completely until they are loose to fully unload the tension.

  • ❌ Never Use a Pipe Wrench or Vise-Grip: When removing the old bars, never clamp a pipe wrench, vise-grip, or air hammer directly onto the center section of the bar. Any gouge, scratch, or nick created on the centerless-ground body acts as a severe "stress riser." Under the massive twisting loads of driving, the bar will rapidly fatigue and snap at that exact damage point. Use a dedicated MOPAR torsion bar removal tool that clamps securely onto the bar or slips into the rear crossmember anchor.

  • ❌ Deep-Clean the Hex Sockets: Over the decades, the female hex receivers inside the lower control arms and the rear chassis crossmember accumulate hardened grease, road grime, and rust. Before sliding the new bars in, thoroughly clean out both receivers using a wire brush and penetrating solvent. If the hex ends do not slide in easily by hand, do not force them with a sledgehammer; verify the sockets are clear of debris.

  • ❌ Anti-Seize is Mandatory: Always apply a generous coat of high-pressure, waterproof anti-seize or heavy moly grease to both male hex ends of the bars before sliding them into position. This allows the bar to slide smoothly into place, prevents the ends from seizing into the chassis over time, and eliminates the annoying metal-on-metal squeaking common in classic MOPAR front clips.

  • ❌ Left & Right Side Sensitivity: MOPAR torsion bars are highly directional and cannot be interchanged. They are stamped on the rear face with an "L" for Left (Driver's side) or "R" for Right (Passenger's side). Torsion bars are structurally pre-stressed during manufacturing to twist in one specific direction. Installing a bar on the wrong side will force the steel to untwist against its structural set, causing the front end to sag rapidly and risking a catastrophic failure under load.
