Torsion Bar Lock & Seal Mopar A/B/E Body

The Torsion Bar Lock & Seal Mopar A/B/E Body is a critical retention component engineered for Mopar muscle cars and street machines built on the A, B, and E platforms. This fastener assembly secures the torsion bar to the suspension frame, preventing unwanted movement during cornering, acceleration, and heavy braking cycles. Whether you're restoring a classic Dodge Charger, Plymouth Road Runner, or Chrysler 300, this lock and seal kit ensures your front suspension geometry remains stable and predictable under all driving conditions.

PROFORGED manufactures this component to OEM specifications, utilizing precision-machined steel and a factory-correct seal design that prevents dust and moisture contamination of the torsion bar anchor point. The lock mechanism features a positive mechanical grip that resists vibration loosening, while the integrated seal guards against corrosion and debris intrusion—critical factors in maintaining suspension performance over decades of ownership. The compact 3.05 x 2.75 x 4.35 inch profile fits seamlessly into original suspension cavities without modification or clearance issues.

This lock and seal assembly is ideal for enthusiasts rebuilding original suspension systems, performance shops upgrading vintage Mopar platforms, and restorers who demand authentic, period-correct components. Installation requires no modification to the suspension subframe or torsion bar itself—simply remove the worn original, clean the mounting surface, and secure the new assembly using a standard socket. Compatibility spans all A-body (1960–1979), B-body (1962–1981), and E-body (1970–1974) Mopar vehicles with factory torsion bar front suspension, making it an essential inventory item for any serious Mopar restoration project.
