QA1's Mopar K-Members are direct bolt-on for your 66-70 Mopar B-Body. Engineered for maximized strength, the tubular design allows for greater header and oil pan clearance. The K-Member comes with engine mount attachment points to accept factory and aftermarket engine mounts. If using a sway bar, the 1966-69 B-body K-members only work with a QA1 sway bar and control arms. The E-body and 1970-72 B-body K-members can be used with a factory sway bar and control arms. Made in the USA.
