Adjustable Control Arms Pair Mopar A/B/E Body

The Adjustable Control Arms Pair for Mopar A/B/E Body vehicles is the foundation of any serious suspension upgrade for classic Chrysler, Dodge, and Plymouth muscle cars. Whether you're restoring a 1970 Dodge Charger, building a street-strip B-Body, or fine-tuning an E-Body platform, these SPC Performance arms replace worn factory control arms that accumulate play and bind over decades. Control arm geometry directly impacts wheel alignment, bump steer, and steering response—making quality replacements essential for both handling and safety on modern roads.

SPC Performance has engineered these adjustable control arms with the flexibility to dial in caster and camber settings without requiring additional shimming or welding. The design accommodates aftermarket suspension geometry changes commonly needed when lowering springs, coilovers, or upgraded sway bars are installed. By adjusting ball joint mounting angles, you gain the ability to correct wheel alignment specs—critical when aggressive camber or caster curves demand precision. The pair weighs 23.15 pounds and ships in a compact package (10.5 x 9.75 x 17 inches), making installation straightforward for shops and home builders alike.

Owners of first-generation A-Body (Dart, Duster), B-Body (Charger, Road Runner, Satellite), and E-Body (Barracuda, Challenger) vehicles benefit most from this upgrade when pursuing track duty, street handling improvements, or restoration correctness. Installation requires disconnecting factory arms at both the frame and spindle, then bolting in the adjustable units—a task any competent mechanic can complete in under two hours per side. These arms integrate seamlessly with OEM ball joints and steering linkage while providing the geometry control that modern performance demands, making them an investment that pays dividends in both wheel alignment accuracy and suspension longevity.
