The QA1 QAP K‑member for 1968–1970 Mopar B‑Body with torsion bar accommodation replaces the factory crossmember to support upgraded suspension geometry and improved front-end control. Offered in three kit levels, it uses strong, lightweight tubular components, enables shock tunability, and can be built in stages. The K‑member is made in the USA and comes with a best-in-class warranty.
