DSE Front Sway Bar Kit - 1-3/8in Diameter (031406DS) - 1973-1977 GM A-Body
Take the wallow out of your classic A-Body and give the front suspension the roll control it needs with the Detroit Speed Front Sway Bar Kit, part number 031406DS. Designed specifically for 1973-1977 GM A-Body applications, this 1-3/8-inch tubular front sway bar addresses the limitations of the smaller factory bar by increasing roll resistance for flatter cornering, improved stability, and a more responsive feel behind the wheel. Detroit Speed's extensive testing showed a dramatic handling improvement on cars with stock suspension and optimized performance when paired with other Detroit Speed suspension components.
The 031406DS is engineered as a complete front sway bar package rather than just a replacement bar. Its tubular construction is complemented by greaseable polyurethane bushings, mounting brackets, end links, frame adapter plates, installation hardware, and grease. With an anti-roll bar rate of 816 pounds per inch, this system provides a substantial handling upgrade for street-driven restorations, restomods, and performance-focused A-Body builds while retaining a straightforward bolt-on approach.
