Torque Boxes 1966-74 A-Body ART-2829 Torque boxes were also known as "hemi boxes" or "double floor plates". Our tests have shown that when combined with our weld-in subframe connectors, the two together provide a 20% decrease in chassis flex, which is also a 20% increase in rigidity. These are not factory-stamped pieces for show car restorations, they are for performance enhancement.

Installation instructions are available here. (Instructions will also be included with shipment.)
