DSE Tubular Lower Control Arms (031207DS) - 1973-1977 GM A-Body
Upgrade the front suspension of your 1973-1977 GM A-Body with the Detroit Speed 031207DS Tubular Lower Control Arms. Designed as performance replacements for the stock lower control arms, these DSE arms combine rigid tubular construction with revised geometry that adds positive caster while retaining the stock spring-pocket location. The result is a stronger, more precise foundation for improved front suspension performance on street-driven, Pro-Touring, and handling-focused A-Body builds.
Detroit Speed builds the 031207DS lower control arms with a robust tubular structure reinforced by gussets and a cross brace. Delrin bushings are installed in steel housings with crush tubes, while CNC-machined tube ends provide precise component fit. Each arm is TIG welded in a fixture to maintain accurate and repeatable geometry, then protected with a durable black powder-coat finish. Lower ball joints, steering stops, and jounce bumpers are included, giving you a complete pair of lower control arms ready for installation.
