K-Member 66-70 Mopar B-Body Stock Steering

The K-Member 66-70 Mopar B-Body Stock Steering from QA1 is an essential chassis component engineered for restorers and performance builders working with 1966–1970 B-body Mopars—including Road Runner, Satellite, and GTX platforms. This fabricated k-member assembly replaces the factory crossmember while maintaining OEM steering geometry and attachment points, making it the go-to choice for drivers who want to preserve original handling characteristics during a full frame-off restoration or modern suspension upgrade. Whether you're sorting a numbers-matching restoration or setting up a restomod, this component provides a solid structural foundation that integrates seamlessly with period-correct steering systems.

QA1's engineering prioritizes dimensional accuracy and robust construction to handle both street and strip duty. The stock steering variant maintains compatibility with the factory pitman arm and drag link setup, eliminating the need for costly aftermarket steering conversion kits if you're preserving authenticity. The assembly weighs 43.3 pounds and measures 21.5 inches wide by 38 inches long, proportions that fit the classic B-body chassis envelope without modification. The structural design incorporates reinforced geometry that accommodates factory-style lower control arm mounts, allowing buyers to pair this k-member with either original suspension arms or modern tubular alternatives depending on their build goals.

Buyers restoring or modifying 1966–1970 Dodge Chargers, Plymouth Road Runners, and GTX models will find this k-member indispensable for sorting chassis rot, correcting suspension geometry, or transitioning to upgraded components without abandoning OEM steering feel. Installation requires unbolting the factory crossmember and positioning this assembly in place; existing motor mounts and frame attachment points align with minimal fabrication. This component is ideal for restoration shops, serious hobbyists, and performance builders who demand precision fitment and the ability to retain or upgrade steering systems without compromising B-body authenticity or handling response.
