This Stage 4 kit replaces a 1978-1988 G-Body's entire front and rear suspension with adjustable, double-shock-valved componentry built for autocross, road course, and drag strip duty in one package. Tubular a-arms, coilover front springs, adjustable trailing arms, and a 3-way rear sway bar work together to raise spindle height, add caster, and give the car a wider handling window than the factory geometry allows.

• Tubular upper and lower front a-arms with 1/2 in. taller ball joints add 1 in. of spindle height for improved camber gain.
• Adjustable upper a-arms add caster without extra shims for a more precise steering feel.
• Front hybrid coilover springs pair with double adjustable Viking shocks offering 361 valving combinations.
• Rear trailing arms use Poly and Roto-Joints with adjustable uppers for pinion angle and lateral location tuning.
